understand the development of the morphology of the strong verbs. At the end of the ten weeks, I knew that my work had only begun. I was intrigued by the idiosyncrasy and many unsolved mysteries of the strong verbs: why were the OED editors so evasive in describing the possible reasons for the preterite of fly to have become flew, a form that is not descended from its original preterite? I wanted to know why the general principle that highly frequent strong verbs tended to be conservative in their morphology and remain strong while infrequent verbs tended to become weak seemed valid, yet there are so many exceptions to that principle. The infrequent freeze is still strong in Present Day English (PDE), yet the frequent help is now weak. The groundwork of my project started with a talk at SHEL, presenting the 1 pilot results of my work thus far and laying out the directions that my future research would take. Two days after my presentation in October 2007, an article appeared in the LA Times reviewing a paper on English irregular past tenses that had just appeared in the high-profile journal Nature, written by mathematicians and biologists with an interest in applying their methodology to language change (Lieberman et al. 2007). It was thus a matter of serendipity that public interest in the history of English past tenses increased just as I was beginning to develop my work into a dissertation project. Lieberman et al. looked at irregular Old English (OE) verbs that are still present in the lexicon of PDE. They gathered frequency data for these verbs, and they found that the lower the frequency of a set of verbs, the higher the percentage of verbs that had been regularized. They calculated the rates at which verbs regularized relative to their frequency. Their goal was to relate the evolution of language to evolution in the hard sciences, such as genetics and nuclear physics. Based on their findings about the verbs, they made predictions about the future of English, such as “wed” being the next verb likely to regularize, and “have” and “be” not being likely to regularize within the lifetime of the English language. The article by Lieberman et al. immediately stirred up a flurry of discussion in both scholarly and popular venues. The media and bloggers responded positively. The author of the only recent book-length study of the English strong verbs, Marcin Krygier, pointed out in a listserv the many philological errors they had made. David Fertig later gave a talk (2009) challenging Lieberman et al.’s emphasis on the regularization of irregular verbs, and their corresponding lack of consideration of the irregularization of regular verbs, as well as challenging the suitability of various individual verbs included in the study. These discussions 2 strengthened my conviction that the topic was not exhausted and that there were serious philological and theoretical issues that were still in need of elucidation. Even prior to the work of Lieberman et al., the past tenses of English verbs fascinated scholars in two fields, psycholinguistics and the history of the English language. Sweet (1900), Jespersen (1931), Long (1944), and Abbott (1957) are a few among the historians of English who have recorded and classified strong verbs at different periods in the language. Psycholinguists have found the strong verbs to be a congenial testing ground for competing models of language change and processing. Psycholinguistic models can be divided into three categories: • Connectionism: all verb preterites are produced analogically (Bybee and Moder 1983; Rumelhart and McClelland 1987; Hare and Elman 1995) • The dual mechanism model: regular verb preterites are produced by rule, and irregular verb preterites are produced through analogy and memorization (Prasada and Pinker 1993; Pinker 1999) • The stochastic rule model: all verb preterites are produced by rules (Albright and Hayes 2003). These three categories of models can be viewed as ranging from purely analogic to purely rule-based. They can also, however, be viewed in terms of the similarity of the two models that attribute all verbs to the same mechanism, in opposition to the model, called the dual mechanism model, that claims regular and irregular verbs are handled fundamentally differently in the grammar. The present dissertation straddles the two emphases, history of English and linguistic processing, that studies of strong verbs have taken. The goal of my work is to account for the diachronic evolution of the strong verbs, and, more 3 specifically, to answer the question of why some verbs have retained their strong inflection while others became weak. I use the findings of theoretical linguistics to propose psycholinguistic motivations for the changes to the strong verbs. I hope that my own findings will add to the data on the history of the strong verbs in a way that is useful to further research on modelling language change. Toward this end, the dissertation brings to the table freshly gathered philological data, evaluates existing hypotheses in light of the data, and develops additional new hypotheses. To provide the reader with an understanding of the existing knowledge on which my study builds, the following two sections introduce the history of the strong verbs in Old, Middle, and Present Day English, and work that has been done on the subject hitherto. Section 1.2 presents the classification of and major changes to the strong verb system in the history of English, Section 1.3 surveys the studies on the shoulders of which my own work stands, and the following sections present an introduction to the structure and methodology of the dissertation. 1.2 History of the Strong Verbs In this section, I survey briefly the received knowledge on English strong verbs. The strong verbs are defined as those that form their past tense by changing the root vowel, such as run ∼ ran, in contradistinction to weak verbs, which form their past tense by the addition of a suffix with a dental stop, such as walk ∼ walked, and to irregular verbs that form their past tense by both or neither means, such as keep ∼ kept or go ∼ went. 4 1.2.1 Present Day English In PDE, the means of marking past tense are • suppletion (go ∼ went) • vowel change (come ∼ came) • addition of a suffix ending in /d/ or /t/ (walk ∼ walked) • no change (put ∼ put) • vowel change plus suffix addition (keep ∼ kept). Huddleston and Pullum (2002: 1600-09) list 90 uncompounded verbs that form their past tense through vowel change alone. Of these, 75 are descended from original strong verbs. Others, such as bleed, acquired present-preterite vowel alternations not through morphological change, but through a series of regular phonological changes that triggered vowel shortening. Thus, despite their different diachronic origins, bleed and come are classified alike synchronically. These verbs are discussed in more detail in Chapter 5, section 1. The classification of irregular verbs in Huddleston and Pullum is along synchronic lines, appropriate to a synchronic grammar. The verbs are grouped according to the behavior of the vowel and the allomorphy of the dental preterite suffix, if any, as well as any irregular consonant changes. This classification leads stand, which was a strong verb in OE, to be classified most closely with make and have, and to be classified more closely to originally weak catch than to the originally strong verbs, such as shake, with which stand patterned in OE. The classification of the present dissertation is along diachronic lines, appropriate to a work on the history of English. Stand is treated as a strong verb, like 5 shake, and original weak verbs like make and have are not included. The exception is weak verbs ending in a dental, which are treated in Chapter 5, as noted, but in the rest of the dissertation they are kept separate from the historically strong verbs. 1.2.2 Old English Hogg and Fulk’s A Grammar of Old English (forthcoming from Wiley-Blackwell, December 8, 2010)1 divides OE verbs into the categories of strong, weak, preteritepresent, and athematic. Strong verbs are further subdivided into seven main classes, according to their four principal parts. The principal parts are the infinitive, 3rd singular preterite indicative, plural preterite indicative, and past participle. Knowing the vocalism of each of these principal parts allows one to conjugate all verbal forms. Table 1.1 shows the principal parts of classes I-VI. Class VII, in Proto-Germanic, formed its preterite by means of reduplication and ablaut. By the time of OE, reduplication had been lost as an active process, though traces remained in some verbs, and the ablaut had been greatly disturbed by various phonological and morphological changes. The result was a veritable grab-bag of ablaut patterns, which scholars still assign to the same class. Table 1.1 shows the principal parts of two subclasses of Class VII, several of whose members have remained in the language to the present day, and which are the subject of much of Chapter 3. Though this system is the one traditionally used to describe OE, it is a better description of Proto-Germanic, because of the phonological changes that by OE had splintered several of the classes into subclasses. Additionally, morphological variation occurred. Several members exhibited forms from different classes, and 6 Table 1.1: OE Strong Verb Classes ’drive’ ’freeze’ ’sing’ ’bear’ ’weave’ ’contend’ ’know’ ’blossom’ Class Class Class Class Class Class Class Class I II III IV V VI VIIa VIIb Infinitive drīfan frēosan singan beran wefan sacan cnāwan blōwan Pret. sg. drāf frēas sang bær wæf sōc cnēow blēow Pret. pl. drifon fruron sungon bǣron wǣfon sōcon cnēowon blēowon Past Participle drifen froren sungen boren wefen sacen cnāwen blōwen some 60 verbs exhibited weak forms, e.g. slēpade and slæpte, which are weak preterites of the strong verb slǣpan. See Appendix I for a full list of OE strong verb variation. 1.2.3 Middle English (1100-1500) Beginning in late OE, the unstressed vowels in the final syllables became reduced toward schwa or a schwa-like vowel. The inflectional endings of the OE strong verb principal parts, namely <-an> for the infinitive, <-on> for the preterite plural, and <-en> for the past participle, came to be written <-en> in ME, which I represent, following Lass (1992: 78) as [-@n]. During ME, these final syllables were lost entirely. In the case of sonorant-final verbal stems, the vowel was instead often syncopated, even as early as OE, as in the adjective <gecorn> ’chosen’, which is syncopated from gecoren. It is the syncopated participle that survives in PDE sonorant-final strong verbs such as torn and sworn. Various other phonological changes affected the ablauting vowel: descriptions of these changes are contained within the dissertation wherever appropriate, especially in section 2 of Chapter 3, 7 and section 1 of Chapter 5. During ME, the preterite singular and plural fell together, such that no strong verb in PDE has more than three principal parts, as in drive ∼ drove ∼ driven. In some cases, the participle also merged with the preterite, as in find ∼ found. During ME, this process was ongoing. For these reasons, there is no separate tradition of classification for ME strong verbs. Generally, the seven-class system of Proto-Germanic and OE is used unchanged, as by Lass in CHEL (1992) and Mossé in The Handbook of Middle English (1968). Fisiak (1968) attempts a classification in the most general terms, according to how many ablaut alternates a verb displayed in a given century, but this can only be an approximate description of ME verbs, as the number of alternates varied not only diachronically but also diatopically. The strong verbs of ME prove impossible to categorize in any specific way. The records abound in not only chronological and dialectal variation, but also free variation within a given text. Nearly every strong verb exhibits both strong and weak past tense forms in ME, according to Welna (1996: 120). He lists all the preterites and past participles he was able to turn up. Of the 157 strong verbs in his databases, he records 17 for which he did not find weak past tenses. Of those, my work with the Middle English Dictionary (MED) has turned up weak past tenses, or mixed past tenses with both a vowel change and a dental suffix, for 5, leaving 12 of the 157 verbs with no attestation of weak inflection during ME. The verbs with no weak forms are bid, bide, bind, come, eat, find, shit, sing, sling, stand, stride, and wind. Some of the 12, such as come, are highly frequent and are exempt from the generalization that ME strong verbs exhibit weak forms, but surprisingly frequent verbs also exhibit weak preterites, such as hōldede and 8 speked. Others that do not exhibit weak preterites are low frequency verbs that have few forms attested. It may be assumed that at least some of these occurred with weak forms in the spoken language that are not recorded because of the paucity of attestation of these verbs. 1.3 1.3.1 Literature Survey Bybee and Colleagues Joan Bybee has written a great deal on the English strong and other irregular or semi-regular verbs. The works used most relevant to the material studied in this dissertation are Hooper (Joan Bybee Hooper 1976), Bybee and Slobin (1982), Bybee and Moder (1983), Bybee and Newman (1995), and Bybee (2001). These works argue for the important role of (1) type frequency, (2) token frequency, (3) cue validity, and (4) product-oriented schemas in the evolution of irregular morphology. It will be convenient to give here a definition of these terms, which are employed often in later chapters. The token frequency of a word or form is the number of instances in which it occurs in the language. For example, in English, come is a verb of relatively high token frequency, and wring is a verb of relatively low token frequency. The role of token frequency in the preservation of irregular morphology was being developed as early as the nineteenth century (Paul 1890). It has achieved a place in the handbooks of historical linguistics as an important explanatory factor in language change (e.g. Mańczak 1980). Work by Bybee and colleagues has supported the token frequency hypothesis, according to which forms that are more frequent are more likely to be conservative in their morphology. Token frequency is thus an 9 important factor in the preservation of strong inflection. The type frequency of a pattern is the number of words that belong to that pattern. For example, the type frequency of the ablaut pattern to which come belongs is low, because only a single verb has [2] in the present and [ei] in the past. In contrast, the type frequency of the pattern to which wring belongs is high, because several verbs have the same ablaut pattern, e.g. sting, sling, cling, fling. Type frequency is found by Bybee and colleagues to be most important in the productivity of inflectional patterns, by which is meant the extension of a pattern to words to which it did not originally apply. For example, the inflection sting ∼ stung has been productive in English in extending to denominal verbs, e.g. string, loanwords, e.g. sling, originally weak verbs, e.g. dig, and nonce words created by researchers for linguistic experiments, e.g. spling, which was used by Albright and Hayes (2003: 42) in an experiment that is described more fully in section 1.3.3. Cue validity is a measure of how well the presence of a feature predicts membership in a category. For example, the feature of possessing wings is a good predictor of being a member of the avian category, but not a perfect predictor, as not all winged objects are birds. Some, for example, are airplanes. Cue validity can be applied to language by considering features such as whether a form ends in a dental stop and categories such as preterite verb, and calculating to what extent the presence of a final dental stop is a good predictor that a word is a preterite verb, as opposed to, say, a noun, or present verb. Bybee defines product-oriented schemas in contrast to generative source-oriented rules. Using the verbs as an example, whereas generative rules specify how a speaker shall alter a present to arrive at a preterite, a product-oriented schema 10 specifies the form a preterite shall take, without reference to the present. (Bybee and Slobin 1982: 103) A source-oriented rule might state that the present of a verb such as grow shall substitute /u/ for the vowel of the present tense, as in example (1) below. A product-oriented schema might state that preterites shall have a word-final /u/. (1) Generating <-ew> preterites V → /u/ / __# A product-oriented schemas relies most crucially on phonological similarity. Phonological similarity is defined by Bybee and Moder (1983) as a measure of the number of features that two forms have in common. For example, sting is phonologically similar to cling, sharing the sequence -ing. Each, however, is more similar to sling than to each other. Cling and sling share the sequence -ling, and sting and sling share -ing as well as an initial s-. The product-oriented schema that produces the preterites for such verbs abstracts the similarities of the preterites stung, slung, clung, and so forth, and specifies that preterites with that preterites ending in -ung are well-formed, especially if they also begin with an s-. 1.3.2 Lieberman et al. 2007 Lieberman et al. gathered a list of 177 irregular OE verbs that are still present in the lexicon of PDE. Of the 177, they classify 98 as still irregular in PDE. Their selection of verbs to study is different than those listed in Huddleston and Pullum (2002), as their study is diachronically rather than synchronically oriented. Even in comparison with other diachronically oriented works, deciding whether to 11 include a verb can involve a judgment call. Sleep and read, for instance, had both strong and weak forms in OE. Lieberman et al. classify sleep as irregular in OE and read as regular, thereby excluding read from their study. In contrast, other studies, e.g. Krygier (1994), exclude sleep from the OE strong verbs on the grounds that it was predominantly weak, but deem that read had sufficiently many strong forms to be included as an OE strong verb. As neither Krygier nor Lieberman et al. relied on an OE corpus, the exact criteria for inclusion cannot be pinned down. Forsake is listed by Lieberman et al. (2007 supp. 12) as irregular in ME and PDE, but regular in OE. My search of the Dictionary of Old English Corpus shows that the preterite singular was exclusively strong, forsacan ∼ forsōc, so I include it as a verb strong in all periods, and moreover one that retained its inherited form. Lieberman et al. used CELEX, a corpus of PDE constructed at the Dutch Centre for Lexical Information (Baayen et al. 1995), to gather frequency data, and organized the verbs into 6 different bins according to the logarithms of their frequencies. They found that the lower the frequency of the bin, the higher the percentage of verbs that had been regularized. They calculated the relative regularization rates of the verbs in each bin, and determined a “half-life” of verbs in different bins. The authors are not linguists, and, as noted above, linguists have made several objections. Among them are those posted to the ANSAX listserv by Krygier. One of his objections is their treatment of have as an irregular OE verb. In OE, habban belonged to the third of the three classes of weak verbs. On the one hand, Class 3 comprised only four members, so in that sense habban may be considered irregular. However, the irregularity that Lieberman et al. are considering is irregularity of the past tense. The past tense of habban added the dental suffix to the root, which 12 is regular for a weak verb. The irregularity of the past tense of have, the loss of the /v/ before the suffix, entered the language in ME. So it is at least disputable whether the preterite of have can be considered irregular throughout the history of English. Krygier also objects to their dismissal of frequency changes between OE and PDE, pointing out that they report large changes in frequency for 10% of their verbs. These changes, he says, are sufficient to warrant further investigation. Fertig (2009) argued that many of the PDE verbs Lieberman et al. claim are descended from OE strong verbs are actually the result of denominalization in ME, or the merger of a strong and a weak verb, making the rate of regularization of verbs less striking than Lieberman et al. report. Walk, which comes in part from OE strong wealcan and in part from weak wealcian, is an example of a strong and a weak verb falling together. The verb yelp, OE gielpan, had the meaning of ’to boast’, and all attested strong forms in ME have that meaning. Weak forms have the meaning ’to utter a sharp and shrill cry’, which is the meaning of the noun yelp, ’a sharp and shrill cry’. His conclusion is therefore that PDE weak yelp comes not from OE strong gielpan, but is a denominal verb. Fertig also objects to the one-sided view that looks only at morphological change in the direction of regularization. He presents a number of regular verbs that have irregularized, such as wear from OE weak werian, and argues that these irregularized verbs are necessary to a balanced understanding of the history of English irregular verbs. Fertig’s findings are covered in more detail in Chapter 5, section 4.1. The article by Lieberman et al. is also limited by looking only at token frequency. They do not consider type frequency, nor phonological similarity, which play a role in morphological development. Similar verbs are likely to be treated similarly, which leads to developments that token frequency would not predict. As 13 other studies have shown, e.g. Hare and Elman (1995: 70), cling has always been of low frequency, but it is less likely to become weak because of the many similar verbs that conjugate alike. 1.3.3 Albright and Hayes 2003 In a path-breaking attempt to model the strong verbs, Albright and Hayes (2003) ran computational implementations of the three models mentioned above. The dual mechanism model attributes the production of regular past tenses to rule and the production of irregular production to analogy (Prasada and Pinker 1993). The connectionist model (Rumelhart and McClelland 1987) attributes the production of all past tenses to analogy. The stochastic rule model attributes the production of all past tenses to rules, with each rule weighted according to the frequency with which it is employed in the verbal system. (Hayes and Albright 2003). A rule that changes the past tense to -ung as in string ∼ strung, is more heavily weighted than one that changes the past tense to -ame, as in come ∼ came. Albright and Hayes compared the results of these models to experiments with nonce words that they conducted on native speakers. In their study, the model employing only stochastic rules yielded predictions that matched the results of their experiments with native speakers more closely than either of the other two models. Another important finding of their experiment was the role of phonological similarity in determining the inflectional pattern of all verbs, including regulars. They refer to the phonological features that correlate with a certain pattern as “islands of reliability”. One example of an island of reliability for the regular weak past tense are verbs that end in voiceless fricatives. All 352 verbs in Albright and Hayes’ study ending in voiceless fricatives, such as miss, laugh, and wish, are weak. 14 Voiced fricatives do not form an island of reliability, as e.g. surprise is weak, while rise is strong. 1.3.4 Hare and Elman 1995 Hare and Elman (1995) implemented a connectionist model and tested it using the English strong and weak verbs. They used 106 OE strong verbs and 327 weak verbs as their input, with token frequencies gathered from a concordance of OE (di Paolo and Venezky 1980). These verbs were put through several iterations of their connectionist learning model, representing generations of speakers learning the language. The analogies made by the learning model were compared to the analogies made by speakers in the actual history of the English strong verbs. What they found was an overall tendency for verbs to regularize, with resistance to regularization coming as a result of high token frequency or membership in a class of high type frequency and phonological similarity. One of the strengths of the paper is the use of multiple explanatory factors such as type and token frequency, and phonological similarity, in contrast to works such as Krygier (1994) and Lieberman et al. (2007), each of which is limited to the examination of a single explanatory factor. Challenges to the article have been raised. As mentioned above, Fertig (2009) disagrees that the tendency toward regularization is as strong as Lieberman et al. and Hare and Elman find. Instead he finds more of a balance between regularization and irregularization. Moreover, Hare and Elman do not consider change in frequency over time to be significant enough to investigate. In contrast, the present dissertation finds that in some cases the changes in frequency between Early Middle English (EME) and PDE are found to be significant. The most notable case 15 is those verbs with preterites ending in <-ew>, covered in Chapter 3, Therefore, I consider it advantageous to use frequencies from corpora of two different periods in the history of English. A more minor objection I have is to their treatments of classes IV and V. The two classes are encoded in their model as having an equal number of members, with the result that they changed members randomly. The authors claim that this exchange of members occurred historically. In fact, Class V had 28 members, while Class IV had 18. Despite this, the ultimate direction of change was for Class V members to enter Class IV and adopt past tenses with -o- rather than -e-. There are no verbs in PDE that inflect according to the Class V pattern. I offer an explanation for this surprising behavior in Chapter 4, based on the prevalence of long -o- throughout the strong verb system. 1.3.5 Krygier 1994 Krygier wrote a monograph entitled The Disintegration of the English Strong Verb System (1994). The author’s goal is to study the strong verbs in OE and Middle English (ME) and determine what factors contributed to the weakening of strong verbs. He breaks down ME into several periods, according to century, and also treats the usage of individual authors such as Chaucer and Malory in separate chapters. The chapters contain the inflectional pattern of each strong verb attested in that period or author. These strong verb patterns are followed by a list of all strong verbs with a weak preterite attested that has turned up in Krygier’s corpus and grammar search. Verbs with a weak preterite are described as having undergone the “shift” from strong to weak. Krygier then categorizes the “shifted” verbs according to their stem-final consonants; whether they end in a sonorant, a dental, a labial, etc. Chi-square tests are used to determine whether any of those 16 features is prominent among shifted verbs in a statistically significant way. If the p-value for a feature is less than .1, he concludes that that feature was a significant factor in the “shift” during that period. Krygier’s work is the first attempt to put the study of the history of the strong verbs on a solid quantitative basis. However, the statistics he carries out ignore tokens and focus only on whether or not a verb has an attested a weak preterite, regardless of whether it is rare or abundant in use. The absence of token frequency from his study is a consequence of a reliance on grammars rather than corpora. Even when Krygier gathered data from an author such as Chaucer, he proceeded without taking token frequency into account. Token frequency has long been understood to be a very important factor in the loss or survival of inflectional patterns, at least as far back as Hermann Paul in 1890. Hooper (1976) had already done a survey of several originally strong verbs in English and found a correlation between the preservation or loss of their strong inflection with their token frequency. Even if token frequency was not meant to be the focus of Krygier’s monograph, its importance was worth acknowledging in some way. Additionally, as is reflected in the use of the word “disintegration” in the title, the premise of the work is that the strong verbs, which had formed a robust and stable system in OE, were “on the path to oblivion” (194) by the end of the 14th century. This premise informs the methodology, according to which Krygier treats any strong verb exhibiting a weak preterite as having undergone the “shift” from strong to weak, as though it were fated to be exclusively weak henceforth. However, as noted, nearly every strong verb acquired a weak preterite in ME, yet many of them are exclusively strong today. This is where the absence of token frequency is a serious shortcoming: a verb with many strong preterites but a few 17 weak preterites in a corpus is indistinguishable from a verb with predominantly weak preterites. Yet we would expect different outcomes for them: the former is more likely to remain strong than the latter. To take an example at random, Thomas Malory uses the preterite growed, so Krygier treats grow as having undergone the “shift” from strong to weak. However, in the standard PDE which is the object of the present dissertation’s study, grew is the only preterite used, thus undermining the idea that grew was on the path to oblivion. For this reason, I prefer to describe the ME strong verb system not in terms of disintegration, but in terms of variability. The only review of Krygier (1994) that I have turned up (Nielsen 1997) deplores Krygier’s lack of access to computerized OE corpora, but concludes that it would not have made a final difference to the work. Nielsen does not find any fault with the treatment of ME verbs as “shifted” rather than “fluctuating”. 1.3.6 Long 1944 Long’s The English Strong Verb from Chaucer to Caxton (1944), the author’s New York University dissertation, is a reference work cataloguing all occurrences of strong verb forms in a fifteenth century corpus that the author searched manually. It is an invaluable resource for determining what forms were attested during that period and in what texts. Its shortcoming lies in the fact that it does not provide token frequency data in full. Instead, it records one instance of each form in each text, with no indication of whether a form occurs many times in a text or only once. As this is primarily intended as a reference, the author makes few analytic claims, consisting mostly of statements about the probable source of one analogy or another. 18 1.3.7 Summary Previous work on the strong verbs comes in various flavors: reference works, learning models, investigation of the factors underlying diachronic change, and synchronic psycholinguistic investigation of the way past tenses are processed. Different factors for the preservation and loss of strong verb inflection have been proposed, the most prominent of which are token frequency, type frequency, and phonological similarity. Certain gaps in the literature exist, and this dissertation seeks to fill some of them. Two of the works discussed above, Krygier (1994) and Lieberman et al. (2007), consider only one explanatory factor each: phonological similarity and token frequency, respectively. The present dissertation emphasizes the importance of considering multiple factors to do justice to the complexity of language. Each of the next four chapters of the dissertation considers a different factor, and the final chapter brings them together into a quantitative model. Much diachronic work on the history of English verbs has been carried out without using the full array of theoretical linguistic tools, e.g. Krygier (1994), Lieberman et al. (2007), Hogg (1988), Welna (1991). The primary interest of much of the current linguistic research on the strong verbs, e.g. Bybee and colleagues, Pinker and colleagues (Prasada and Pinker 1993; Pinker 1999), Rumelhart and McClelland (1987), Albright and Hayes (2003), has been psycholinguistics rather than language change. The present dissertation, like Hare and Elman (1995), seeks to unite studies of the history of the English language with recent findings of theoretical lingustics. It differs from all these works, both synchronically and diachronically oriented, in using multiple corpora from different historical periods, rather than dismissing changes in frequency as insignificant. This allows a more nuanced approach with 19 attention to detail for individual verbs, in keeping with the philological training of the author. 1.4 Methodology and Explanatory Factors In OE, there were approximately 367 strong verbs (Welna 1991: 131). Many of these no longer exist in any form in the language, having undergone lexical loss. The purpose of this dissertation is to study these verbs that remain in the PDE lexicon and identify the factors that contributed to the survival of OE strong inflection in some but not in others. Toward this end, new data are presented. The authors of previous work on the subject have not had as many historical resources available to them, and even those who used historical corpora, used only one corpus. I have used multiple corpora for different purposes, and two corpora from different periods for gathering the frequencies of the entire set of strong verbs. I seek both to test existing hypotheses, such as the token frequency hypothesis, as well as to propose new ideas. The role of vowel quantity as a factor in the history of strong verbs is a new suggestion. The role of phonological similarity as a factor has been established in the literature, but the proposal that the survival of the <-ew> preterites correlates with the phonological similarity of the verbs is innovative. These factors are evaluated qualitatively and also quantitatively in Chapter 6, using a linear regression model. The use of the model allows for statistical evaluation of the significance of the proposed factors. The general prediction for survival or loss of strong inflection, according to the token frequency hypothesis, is that analogical leveling affects low frequency items first, and items of high token frequency are likely to retain irregular inflection. The 20 fact that token frequency has a significant effect on the loss and survival of irregular inflection are well documented, and have been discussed in the literature since the nineteenth century (Paul 1890). The methodology of this dissertation is to consider the development of the strong verbs first in light of the token frequency hypothesis, expanding on previous research by using multiple corpora from different periods, and then to seek to explain exceptions to the general rule. The token frequencies for each of the strong verbs are gathered from CELEX, a corpus of PDE, and the Linguistic Atlas of Early Middle English (LAEME), a corpus of Early Middle English. Both corpora are tagged for part of speech and for lemma, making the counts optimally precise. The verbs are organized into classes and subclasses along the lines of the seven-class OE system discussed in section 1.2.2 of this introduction. Tables are presented for each subclass with the EME and PDE frequency counts, sorted in a way that allows the reader to eyeball whether a greater proportion of the verbs that retained their strong inflection are the more frequent verbs, at the top of the table, or not. Cases where frequency predicts survival of strong inflection are identified, as are exceptions where frequency is not such a good predictor. For example, the high frequency of come correctly predicts the preservation of its strong inflection, while the high frequency of help incorrectly predicts that it should be strong in PDE, when it is weak. Some of the exceptions can be accounted for by word shape and cue validity, which have a statistically significant correlation with the development of strong inflection. Features related to word shape, such as “initial consonant cluster” and “final -ng”, are calculated to see to what extent they predict membership in the class of strong verb preterite. The two major subclasses where a correlation is observed are 1) verbs that end in final nasals and velars, such as sing ∼ sang 21 ∼ sung, and 2) verbs with preterites that end in -ew, such as grow. One of the contributions of this dissertation is the hypothesis that initial consonant clusters are a feature that promoted the preservation of strong inflection. Vowel quantity is another factor argued to have played an important role in the outcome of strong verb preterites, with manifold proposed effects. Verbs that did not have long vowels anywhere in their paradigm were more likely to become weak. This is the explanation proposed for the weak outcome of help. If a strong verb had alternate past tense forms in ME, it was likely to select one that had a long vowel. If multiple past tenses with long vowels for a single verb existed, the one with a long open o, /O:/, was selected in Early Modern English (EMnE). Two explanations of the importance of vowel quantity are presented. One posits that long vowels tended to flourish because they enjoyed a numerical dominance that was both interparadigmatic and intraparadigmatic, so that the spread of long vowels gathered momentum. The other posits that long vowels in strong preterites also offered the listener an inherent perceptual advantage over short vowels. Chapter 5 departs from the strict exclusion of verbs that were not strong in OE by looking at the effects of word shape, type frequency, and token frequency on all dental-final verbs. Two dental preterite allomorphs, the one that underlies PDE -ed, as in thread ∼ threaded and the one that underlies the null suffix, as in hit ∼ hit, have been in competition since OE. The former is now the default, whereas the latter was the default for dental-final weak verbs in OE. Word shape is argued to have begun to shift the scales to a preference for the -ed variant, and its type frequency eventually snowballed into the dominant allomorph. Token frequency is argued to have governed which individual verbs retained a preterite without the extra syllable. 22 All the factors are then combined into a single mathematical model of the strong verbs using linear regression. The dental-final weak verbs are again excluded. The model computes the weights for the different factors, which is innovative in the treatment of the history of strong verbs. It is hoped that future work, by the author and by other scholars, will both refine the model and contribute new factors to be tested. 1.5 Scope The primary thrust of this dissertation is morphological, focusing on the selection of verbal preterites from among competing forms. Morphophonology is taken into account where relevant. Syntax is beyond the scope of the work, and semantics is referred to only when a verb behaves aberrantly in a way that appears to result from following the example of a semantically similar verb. Verbs such as niman ‘take’, which no longer exist in English, are excluded. Some of the remaining verbs are strong in PDE, such as come. Some are weak, such as help. Others have mixed inflections, such as crow, which has the preterites crew and crowed. These strong, weak, and mixed verbs are included as objects of this study. Obtaining a precise count of how many are strong and how many are weak depends on one’s principles of categorization. To count as strong for this dissertation, a verb must have a current strong preterite, which may or may not be in competition with a weak preterite. A strong past participle, e.g. mown, is not sufficient to qualify a verb as strong, if a strong preterite, such as mew, no longer exists. Moreover, a verb that lost its strong inflection, and only some centuries later obtained a strong inflection, with no continuity between the OE 23 strong inflection and the PDE strong inflection, counts as a verb that became weak rather than one that remained strong. An example is shit, whose inherited preterite from OE would have been shote, but this form was lost in favor of a weak preterite. Only in the nineteenth century is shat recorded, by analogy with sat. In contrast, verbs that remained mostly strong throughout their history count as strong, even if their current strong preterite is not a continuation of its OE form. Fly had a preterite fleah in OE, and its PDE preterite flew arose through analogy with blew, knew, etc. Because fly was never predominantly weak, it is classified as retaining strong inflection. Verbs excluded from this study include auxiliaries, originally weak verbs, and most verbs that in PDE employ dual strategies for marking the preterite, using both a dental suffix and a vowel change, such as buy ∼ bought and keep ∼ kept. Only verbs that are descended from OE strong verbs are the focus of this study, except, as noted above, the treatment of dental-final weak verbs in Chapter 5. The dissertation also restricts itself with respect to the dialectal diversity of English strong verbs, both synchronic and diachronic. Wakelin (1977: 122-24) lists a number of patterns that PDE dialects display with respect to strong verb morphology. Many strong verbs that have not become weak in the standard, prestige dialects of English have become weak in other dialects, with preterites and past participles such as drinked, stealed, seed, gived, comed. These verbs also exhibit dually marked forms, with a vowel change and a suffix in the preterite or past participle, e.g. drunked, stoled, wored. The reverse phenomenon is also seen: verbs that have become weak in standard English but remain strong in other dialects, such as crope, holp, and washen. The zero-marked preterite is not limited to dental-final strong verbs such as hit in some dialects, but is also 24 extended to other verbs such as begin, see, and come. Still other verbs retain archaic strong preterites such as spak and gav. Moving backward in time, it was noted in section 1.2.3 that ME exhibited a wide range of variation as well. Nearly every strong verb displayed a weak preterite. In addition, many verbs exhibited a great variety of strong preterites. Some of these are only orthographic variants, while others reflect real differences in the pronunciation. Wash, for example, has 5 weak preterite singular forms listed in the MED, and 32 strong preterite singular forms. This diversity of dialectal forms is too great to encompass in a single work, though a study of dialectal variation would be of interest and a valuable line of research to pursue in further work. The present dissertation, therefore, is focused on the standard prestige dialects of standard American English as exemplified in the American Heritage Dictionary, a dictionary that attempts to be conservative. As such, it considers mainly such ME forms as contributed to the standard American English dialect. On occasion, an explanation of forms outside this purview follows naturally from the arguments being advanced. For example, an explanation of the spread in the northern dialect of the Class III preterite fand follows from the explanation of the spread in the west of the preterite fund. Thus both are given, but no attempt is made at a comprehensive explanation of all northern forms. 1.6 Sources A major contribution of the present work is the use of digitized, searchable historical corpora from all periods, including the Dictionary of Old English Corpus, the York-Toronto-Helsinki Parsed Corpus of Old English Prose, the Linguistic Atlas 25 of Early Middle English, the Penn-Helsinki Parsed Corpora of Middle and Early Modern English, and CELEX. The data obtained therefrom will be of use to other scholars. The Dictionary of Old English Corpus contains every extant text from OE. It is invaluable in that respect. However, it is not tagged for grammatical or lexical information, so homographs make some searches impossible. For example, searching for <æt>, the strong preterite of etan ‘eat’, turns up more than 6,000 hits, the majority of which are the preposition æt ‘at’. The York-Toronto-Helsinki Parsed Corpus of Old English Prose, as its title indicates, is tagged for grammatical information, which reduces some of the confusion among forms, though not all, due to confusion among similar lexical items. However, it includes only a subset of the prose texts of OE, meaning that some of the searches that would yield results in the complete corpus give no hits for the smaller corpus. LAEME, the Linguistic Atlas of Early Middle English, which covers a subset of the extant texts between 1150 and 1325, is the corpus from which most of the historical token frequency data in this work have been taken. It is tagged extensively for both grammatical and lexical information, meaning that searches may be carried out with optimal speed and accuracy. The Penn-Helsinki Parsed Corpora of Middle and Early Modern English contains a selection of texts from 1150 to 1710. They are tagged for grammatical information, but not lexical. CELEX was used for the PDE frequencies. It is tagged for both grammatical and lexical information. Different corpora are therefore suitable for different purposes. LAEME and CELEX are suitable for gathering frequencies for large sets of verbs. The Dictionary of Old English Corpus is useful when one would like the frequencies from the entire extant corpus of OE, and is suitable for gathering frequencies for small 26 sets of verbs without many homographs. The Penn-Helsinki corpora are useful for breaking the Middle and Early Modern periods down into centuries and pinpointing changes with greater chronological precision. Previous works have not had access to all of these corpora. Krygier (1994) relied on grammars rather than corpora, except corpora of single authors or manuscripts—the AB manuscript, the Peterborough chronicle, Chaucer, and Malory. Albright and Hayes (2003), Bybee, and Lieberman et al (2007). studied only PDE. Hare and Elman (1995)used the Old English Concordance (di Paolo Healey and Venezky 1980), which is a concordance of the most frequent words in OE. Long (1944) investigated a sizable corpus, but being compelled to do so by hand, was able to study only a single century. LAEME became available only in 2008, and this dissertation is one of the first works to make use of this invaluable resource for EME. 27 Chapter 2 Frequency 2.1 Introduction This chapter examines the strong verbs in light of the frequency hypothesis. According to the frequency hypothesis, words with higher token frequency are more conservative in their morphology. I draw heavily on the works of Bybee and colleagues2 for approaches to frequency studies, though the importance of frequency is not limited to a single linguistic model. Optimality Theory, for example, has been extended to include constraints that are weighted according to token frequency3 . The model used in the present work can be summarized as follows. High frequency forms are more likely to be conservative in their morphology. They are stored more vividly in speakers’ memories, and can be summoned up more readily. Less frequent members are less likely to be conservative in their morphology, because the inherited form is more likely to be forgotten. If the inherited form is more difficult to retrieve, the form is likely to be generated according to the most prominent and relevant pattern in the grammar. Prominence is the result 28 of type frequency: the number of distinct words that exhibit a certain pattern. A pattern such as come ∼ came has many tokens, but only one type, and is thus not prominent as a pattern. Relevance is the result of phonological similarity to the members of that pattern. The pattern cling ∼ clung has high type frequency and has thus been applied to several verbs, such as dig ∼ dug, a verb that was originally weak, and fling ∼ flung, borrowed from a Norse weak verb. However, if a speaker is having difficulty retrieving the past tense of shrive, the lack of similarity between shrive and the members of the cling ∼ clung pattern means that neither shruv nor shrung is a likely possibility. Bybee and colleagues have focused on the importance of token frequency for survival and type frequency and phonological similarity for productivity. The present work emphasizes in addition the cases where items of low frequency are susceptible to the factors that govern productivity. This is not a new concept, but applications of it in several cases will be new. This chapter presents the token frequency data for the strong verbs, from Early Middle English (EME) and from Present Day English (PDE). The choice of periods was governed partially by theoretical reasons and partly by convenience. Because the purpose of this work is to explain the inflectional outcomes of originally strong verbs in PDE, data from PDE should be included. Because the approach is historical, data from an earlier period or periods should be included. Hare and Elman (1995) found little change in the frequencies of strong verbs between Old English (OE) and Middle English (ME). For this reason, the payoff for including multiple historical periods was judged not to be significant enough to warrant the time and effort that would be required. The minor fluctuations in frequencies between OE and EME, between EME and (Late Middle English) LME, and between LME and 29 EMnE are not usually distinguishable from chance, given the nature of the data. For PDE frequencies, the CELEX corpus was used, and accessed using the online WebCelex site (Baayen et al. 1995). EME was chosen as the source for historical data largely because of the Linguistic Atlas of Early Middle English (LAEME), recently made available online. LAEME greatly facilitates corpus studies by being not only tagged for grammatical information but also lemmatized. The great variability in spelling in ME makes corpora without lemmatization, such as the Penn-Helsinki corpora, less easy to extract frequency data for strong verbs from, though it is an invaluable resource for historical syntax. Using EME makes sense for linguistic reasons as well. The OE corpus exhibits some variation in strong verb inflection, both in the interchange of members among strong verb classes, and in the occasional weak form of a strong verb. The full list of strong verbs with weak forms is given in Appendix 1. In ME, nearly every strong verb acquired a weak preterite in addition to its strong preterites (Welna 1996: 120), and the variation in strong preterites increased with the passing of time. Reduction of the distinction between the 1st and 3rd preterite singular and the plural and 2nd singular preterite was also ongoing. All preterites were the process of being collapsed under a single principal part during ME. Significant changes in semantics and confusion among verbs also emerged, particularly in the falling together of strong and weak parallels. EME is the period most chronologically removed from PDE that still exhibits much of the variety in which we are interested. In this chapter, the verbs are organized according to the standard seven OE classes. No real organization for ME strong verbs exists, due to the extent of 30 the inflectional variation, yet there are clear cases where PDE verbs are conservative because of the existence of many other similar verbs with the same pattern throughout their history. The OE system, being straightforward, provides a starting point for analyzing the behavior of strong verbs that act in families. In cases where the ME verbs have departed from any possibility of being organized along OE lines, the ease of presentation is still valuable, and the differences between OE and ME are discussed as they arise. This chapter identifies cases where the frequency hypothesis holds, and cases where it does not. The latter are the cases where further explanation is needed. They are the subject of the rest of the dissertation. The frequencies given, unless otherwise specified, represent the total number of verbal forms in the corpus. For the LAEME corpus, the total was obtained by searching for all tags beginning with <v>. In the CELEX corpus, the total was obtained by searching for verbs for which the value in the the column “Class” is <V>. In all cases, prefixed forms are included on the assumption that, for example, forgot contributes to the survival of got, and vice versa. In two cases, only a prefixed form survives in PDE: begin and forsake, for the original roots gin and sake are no longer independent verbs. In the appendix, the frequencies of verbs are broken down into present, preterite, and participle. 2.2 Class I verbs 31 Table 2.1: Class I Token Frequencies PDE outcome S S W S S S S S W W W W W S S W S/W S/W W Verb rise write bide drive ride smite shrive shine bite glide gripe spew slide strike stride writhe cleave shit whine LAEME frequency 357 242 228 185 128 127 84 61 50 48 34 26 22 13 7 7 7 1 0 PDE outcome S S S S S S W W S W W W W S/W S W W W S 32 Verb write rise drive strike shine ride slide bite stride writhe glide whine bide cleave smite shit spew gripe shrive CELEX frequency 8412 4574 3908 1999 1625 1072 637 494 236 130 116 116 97 75 58 42 41 12 6 For the present discussion, shit and cleave are omitted. Shit permits the preterites shit, shitted, and shat, and cleave permits the preterites cleaved, cleft, and clove. Shit is treated as weak in this dissertation, because the original strong preterite, shote, was lost from the language. It is not possible to connect this loss directly with the low attestation of the verb from the written corpora, however. One assumes a priori that the written attestation does not adequately reflect the spoken attestation, because of the taboo nature of shit. Inadequate written attestation may be the case among many verbs, but shit is one case where it can safely be assumed. The preterites shat and shitted are treated in further detail in the discussion of dental-final verbs in Chapter 5. Cleave is a philologically complicated verb, representing the confusion of three OE verbs: Class I strong verb clīfan ‘adhere’, Class 2 weak verb clifian/clēofian ‘adhere’, and Class II strong verb clēofan ‘split’. Leaving aside those two verbs, then, there are 9 verbs with strong outcomes: drive, ride, rise, shine, shrive, smite, stride, strike, and write, and 8 verbs with weak outcomes: bide, bite, glide, gripe, slide, spew, whine, and writhe. Of the verbs that became weak, bite and slide later underwent the regular operation of phonological changes, giving them past tenses that are synchronically strong in PDE. See Chapter 5 for discussion of vowel shortening in weak preterites and the effects on dental-final verbs. They are here treated as weak, in order to test the hypothesis about morphology, viz. that verbs of sufficiently low frequency lost their strong preterites in favor of weak preterites. Later phonological changes are a separate problem. The frequency hypothesis says that the 9 verbs at the top of the frequency chart should have come out strong and the 8 verbs at the bottom of the chart 33 should have come out weak. In the LAEME data, the exceptions are bide, strike, and stride. Bide is the third most frequent of the verbs in Table 2.1, with an absolute frequency of 228, so it is expected to be strong, yet it is weak in PDE. In contrast, strike appears near the bottom of the LAEME verbs in the table, with a frequency of only 13, so it is expected to be weak. Stride has a frequency of 7 in LAEME, yet it too is strong in PDE. In the CELEX data, bide and strike conform to expectations, suggesting that a change in frequency was responsible for the weakening of bide, with an absolute frequency of 97, and the preservation of the strong preterite of strike, with an absolute frequency of 1999. Stride more or less conforms to expectations in the CELEX data, given that no verb above it is synchronically weak in PDE. Slide and bite, historically weak, have become of sufficiently high frequency that their preterites slid and bit have not been replaced with slided and bited. Thus, the list of CELEX verbs from write, at the top, down to stride, consists entirely of synchronically strong verbs of relatively high frequency. Another crux faces us with strike, which has as its preterite not the expected stroke, but struck. The form struck comes from analogy with Class III verbs such as string ∼ strung. The Class III verbs are discussed in more detail in Chapter 3. Bybee and Moder (1983) treat them in terms of family resemblances. According to the theory of family resemblances, there exists a set of features pertaining to the class. It is not necessary for a verb in the class to have all the features, but it must share at least some features with other members of the class. The relevant features found by Bybee and Moder for Class III include an initial /s/, an initial consonant cluster, a nasal in the coda, and a velar in the coda. Strike shares all of these features except the nasal, and thus it was a good potential 34 candidate for joining this class. Hogg (1988) wrote on struck and concluded much the same, using different terminology. In the process he rejected, correctly, the ad hoc phonological explanation of Ekwall (1975) according to which /stro:k/ became /stru:k/, which then shortened and lowered to /str2k/. See Hogg for the difficulties of that explanation. I am not, however, in agreement with his idea that avoidance of homophony with stroke is a plausible factor. The preterites of drive, ride, rise, and write are homophonous with the nouns drove, road, rose, and rote. Contrary to his explanation of avoidance of homophony in this class, the OED suggests that homophony with the noun abode may have been partially responsible for the survival of the preterite abode into the nineteenth century, after the loss of the preterite bode. There is no need to postulate avoidance of homophony in the case of strike, because it fits so well the criteria for membership in Class III, and is the only verb of Class I to do so. The frequency hypothesis predicts that shrive and smite, which are the strong verbs of the lowest frequency in CELEX, are expected to be among the next to become weak. Their formerly high frequencies account for the fact that they have not yet entirely become weak. They originally had high frequencies—respectively 84 and 127 in LAEME. Therefore, ME speakers had less difficulty retrieving shrove and smote than with the preterites of verbs that were less frequent at the time. They thus produced shrived and smited less often than they would have, if shrive and smite had been less frequent. Shrove and smote were therefore relatively salient as preterites in recent history, and they remained at least somewhat accessible to speakers longer than verbs of lower frequency. Overall, the verbs of Class I support the frequency hypothesis, especially when both EME and PDE frequencies are taken into account. 35 2.3 Class II verbs The Class II strong verbs of OE that did not undergo lexical loss and that survive into PDE are bid, brew, brook, bow, choose, chew, cleave, creep, dive, flee, fly, sneeze, freeze, lie4 , reek, rue, shoot, shove, seethe, sprout, sup. The form sneeze arose following the disappearance of fnēosan from the spoken language in favor of neeze. According to the OED, the form sneeze with initial /s/ may have been a result of the misinterpretation of <nese> in the written language, if <> was incorrectly taken as <f>. Since sneeze is descended directly from fnēosan, it is included in this list, though its history is very unusual and borders on calling for exclusion due to lexical loss. However, Craig Melchert, in an email communication, suggested to me an alternative explanation: the influence of other verbs with snthat refer to noises made by humans with the nose as well as the mouth: snore, snarl, sniff, snuff(le). Table 2.2 shows the LAEME frequences of Class II verbs and their preterites. 36 Table 2.2: Class II Token Frequencies PDE outcome W S W W S/W S W W?

Similarly bid, which represents the confusion of Class II bēodan and Class V biddan. Dive results from a fusion of Class II dūfan and weak difian, and it became weak. From the nineteenth century, dive also acquired the strong preterite dove by analogy with Class I verbs such as drive, and both strong and weak preterites are prominent in PDE. Nineteen verbs are left, of which only three or four are strong. The verb of dubitable outcome is shoot. According to the OED (s.v. shoot), the preterite shot may derive from the weak verb scotian, or it may have been influenced by the strong past participle shotten. It may also derive, via vowel-shortening before a dental, from the ME preterite shōte, which may derive from the strong preterite scēat. In fact, as the OED states, all of these may have contributed to the PDE form shot. Omitting shoot, eighteen verbs are left, of which three are strong. This represents a survival rate of one in six verbs, or 17%. Compare the 50% survival rate of Class I verbs. This state of affairs can be explained partly by the lower frequency of the Class II verbs as well as by their lower phonological coherence. The average frequency of all the Class I verbs is 1244, and the average frequency of all the Class II verbs is 498, somewhat less than half. The higher absolute frequency of the Class I verbs contributed to their conservative behavior. Turning to phonological coherence, we see that nearly all the Class I verbs had /i:/ in the present and a coda that was resistent to phonological change. In contrast, the Class II verbs exhibited more variety already in OE, and the variety was exacerbated by ME sound laws. In OE, the vowel of the present might be <ēo> /eo/ or <ū> /u:/. The reasons for the difference are unrecoverable, but some analogy with Class I verbs may be responsible (Hogg 1988: 153). ME diphthongizations affected all verbs that had 38 ended in /g/ or /w/, resulting in changes to the present and preterite of bow, brew, chew, flee, fly, lie, and rue. Moreover, though the regular outcome of OE /eo/ was /e:/, an alternate outcome /O:/ was also found. The former is represented in freeze and the latter in choose. Thus, of the three Class II verbs that remain fully strong, no two are alike. Freeze and choose have the inherited preterite but dissimilar presents, and fly acquired its preterite flew by analogy with Class VII verbs such as grow. See Chapter 3 for further discussion of fly, as well as of the related verb flee. The correlation of the low survival rate of the Class II verbs with their low phonological coherence suggests that phonological coherence is important for survival. Bybee and colleagues focus on the role of token frequency in survival and on phonological coherence for productivity, but the disintegration of Class II provides one of several cases in the present work that indicates the overlap of survival and productivity. Aside from bide, the verbs from LAEME the top of Table I consistently remained strong down to a frequency of 61. Verbs of significantly higher frequency in Table 2.2, such as flee, bow, lie, and rue, are weak. Another interesting observation on relative frequency and survival is that choose, fly, and flee, the verbs that remain strong, are scattered throughout the LAEME column, but concentrated near the top of the CELEX column. The implication is that either the texts in LAEME reflect poorly the actual frequencies of fly and especially freeze, or that the frequencies increased early enough for the strong preterites to be preserved. 39 2.4 Class III Verbs The Class III strong verbs can be divided into three sub-classes. The first subclass, here called Class IIIa, following Krygier, includes verbs that ended in a nasal followed by another consonant. The verbs of that subclass that did not undergo lexical loss and that survive into PDE are bind, burn, climb, cling, drink, find, fling, (be)gin, grind, run, shrink, sink, sing, slink, sling, spin, spring, stink, sting, swim, swing, wind, win, wring. The second sub-class, here called Class IIIb, includes verbs that ended in a liquid followed by another consonant. The verbs of that subclass that did not undergo lexical loss and that survive into PDE are bark, carve, delve, yield, yelp, help, melt, mourn, smart, spurn, starve, swallow, swell, swerve, warp. The third sub-class, here called Class IIIc, includes verbs that originally belonged to Class V, but transferred to Class III after a dental element was added to the end (Wright 1954: 269). The verbs of that subclass that did not undergo lexical loss and that survive into PDE are burst, braid, fight, and thresh/thrash. Burn and run are the results of mergers of two verbs each, with each verb subject to metathesis. Burn results from Class III strong brinnan and weak bærnan. Run results from Class III rinnan and ME rinnen/rennen from ON rinna/renna. For a more detailed history of the metathesized forms and the development of burn and run, see the OED. Also subject to metathesis were burst and thresh/thrash. Tables 2.3 through 2.5 show the LAEME and CELEX frequencies for Class III verbs. 40 Table 2.3: Class IIIa Token Frequencies PDE outcome S S S S W S S S S S S S S S S S W S S S S S S S Verb (be)gin find sing bind burn run win drink stink spring sting wind wring grind sink swim climb cling sling swing shrink spin slink fling LAEME frequency 938 806 393 285 2615 225 211 183 106 104 56 46 31 28 23 22 18 11 5 3 2 2 0 0 PDE outcome S S S S S W W S S S S S S S S S S S S S S S S S 41 Verb find (be)gin run win drink climb burn sing swing sink swim spring grind cling spin fling shrink wind bind sting wring stink slink sling CELEX frequency 19525 12254 7970 2762 2321 1643 1577 1407 1001 894 837 603 491 489 458 425 364 323 321 151 120 72 30 30 Table 2.4: Class IIIb Token Frequencies PDE outcome W W W W W W W W W W W W W W W Verb LAEME frequency help 300 yield 223 warp 214 swallow 53 mourn 47 carve 36 starve 34 melt 31 yelp 30 delve 27 smart 22 swell 17 bark 9 spurn 2 swerve 0 PDE outcome W W W W W W W W W W W W W W W Verb CELEX frequency help 6956 swallow 594 melt 436 starve 364 carve 350 yield 329 swell 270 bark 181 mourn 110 swerve 73 warp 57 spurn 44 smart 30 delve 28 yelp 21 Table 2.5: Class IIIc Token Frequencies PDE outcome S W W W Verb fight burst braid thresh/thrash LAEME frequency 146 57 57 8 PDE outcome S W W W Verb fight burst thresh/thrash braid CELEX frequency 2554 682 180 60 Members of Class IIIa almost universally retained their strong inflection, members of Class IIIb lost their strong inflection, and members of Class IIIc retained or lost strong inflection in accordance with token frequency. Behaving according to token frequency is the exception for Class III. For Class IIIa, it is apparent that class size and phonological similarity among members was crucial for survival, just as it was for the extension of the pattern to other verbs. The phonological 42 similarity of Class IIIa verbs is treated at greater length in Chapter 3. When the preterite of a low frequency verb such as shrink was produced, the inherited form was difficult or impossible to retrieve. Because shrink fit a common ablaut pattern, its inherited preterite was generated in cases where it might not have been frequent enough to summon from memory. Had it not belonged to such a common pattern, we can expect that its inherited preterite might have been lost. It is worth noting that the two weak verbs, burn and climb, are the most dissimilar to the others. Climb underwent lengthening of the vowel in the present, causing it to resemble verbs such as bind, but the final stop was lost in the reduction of /mb/ clusters, causing climb to resemble neither sing nor bind. When the Elizabethans attempted to generate an archaic strong preterite for climb, they did not use the Class III verbs as their model, indicating that they did not find it similar enough to be a member. In keeping with the argument that productivity and survival are related, part of the reason clamb/clomb did not survive was lack of support from other members. Fusion with a weak counterpart played a role in the weakening of burn, but other verbs fused with weak counterparts and retained strong preterites. One such verb seen above was cleave, which retains clove as one of its preterite variants. Subsequent to the metathesis of vowel and liquid, burn had a coda ending in a liquid + consonant, which no longer resembled Class IIIa verbs. Moreover, burn came to resemble Class IIIb verbs, which, like Class IIIa verbs, do not conform to the frequency hypothesis. In this case, they all became weak, irrespective of frequency. Chapter 4 deals in further detail with the verbs ending in liquid + consonant clusters and proposes a hypothesis based on vowel quantity for the loss of the strong preterites. 43 2.5 Class IV and V Most verbs in classes IV and V had identical ablaut except for the past participle, where Class IV had /o/ and Class V had /e/. In OE and ME, members of one class freely adopted the participial vowel of the other. In EME, Class IV won, spreading the o-vowel not only to the participle of the Class V verbs, but also to the preterites of both classes. For this reason, I treat the two classes as one. Several verbs, especially the high frequency ones, underwent various idiosyncratic or limited changes relative to the rest of the class. Sometimes these were triggered by the Proto-Germanic morphology, such as when *bed- added the suffix -jan and became biddan, likewise for licgan and sittan. Others were purely phonological, such as the breaking of /e/ to /ie/ following /g/, as in giefan and gietan. The latter two verbs I include in the table, though the quality of the first consonant in PDE give and get comes not from the OE, which would have yielded /j/, but from Old Norse (ON). Despite the ON origin of these verbs, which existed alongside their inherited variants yeve and yet throughout ME, their continued strong inflection is a result of the fact that their token frequency was always high. The strong inflection of stick comes from Class III, and the verb itself is the result of a merger between weak stician and Class V stecan. Table 2.6 presents the token frequency data from LAEME and CELEX for Class IV and V verbs. 44 Table 2.6: Classes IV and V Token Frequencies PDE outcome S S S S S S S S S S S W S S W S W W S W S W Verb come see give speak biddan bear licgan sit get gitan break eat wreak steal tear mete stecan shear reap tread knead weave weigh LAEME frequency 3477 1916 1250 1006 819 682 522 418 134 276 331 248 88 82 34 21 21 21 19 18 3 3 2 45 PDE outcome S S S S S S S S S Verb come get see give sit speak licgan eat break CELEX frequency 50327 45811 37213 23508 8978 6665 5796 5194 4102 S S S S W S S S W W W W W bear stecan tear steal weigh biddan weave tread reap shear knead wreak mete 1934 1683 1101 941 632 389 262 217 78 71 52 24 0 In all of the corpora searched, through all of the time periods from OE through PDE, come emerges consistently as the single most frequent strong verb. Classes IV and V include other high frequency verbs, such as see and give, that retained strong inflections of low or unique type frequency. In general, the CELEX data do a somewhat better job of predicting strong and weak outcome. Only for weigh is the outcome incorrectly predicted: predicted to be strong when it is in fact weak. We saw in Class II that OE verbs with /g/ in the codas, like wegan, underwent phonological changes in EME that caused them to lose resemblance to the other verbs of their class. The weak outcome of weigh may be attributed in part to this, as well as in part to confusion with the weak verb wecgan. Wreak and mete are examples of verbs that declined in frequency over time and lost their strong inflection. Not all verbs that declined in frequency did so: Class I smite, for example, declined significantly from ME and is hardly in use in PDE, but Merriam-Webster records only a strong preterite smote and strong participles smitten and smote. 2.6 Class VI Verbs The Class VI strong verbs of OE that did not undergo lexical loss and that survive into PDE are ache, bake, drag/draw, fare, flay, gnaw, grave6 , heave, lade, laugh, (for)sake, shake, shave, slay, stand, step, swear, wade, wake, and wash. The philological difficulties with these verbs are as follows. Drag is either from ON, or, if from OE dragan, a special dialectal development. The regular development in the south is draw. Wake involves a fusion of a weak verb wacian and a Class VI strong verb that occurs only in the preterite, unless one assigns an attested wæcnan 46 to the present. In any case, the PDE strong preterite woke, if from OE wōc, should have come out so as to rhyme with shook. Wash exhibited many variant forms in OE and ME, which causes overlap in search results with wax. Fortunately, LAEME and CELEX are both lemmatized, though the other corpora are not, so frequency counts from other periods reflect a certain amount of confusion between wash and wax. The verbs that retain the regular strong Class VI inflection are (for)sake, shake, and stand. The ON Class VI verb taka entered the language in ME and has likewise retained its inflection as take. The verbs that have become weak are ache, bake, drag (if from dragan), fare, flay, gnaw, grave, heave, lade7 , laugh, shave, step, wade, and wash. Some verbs that are weak in the preterite retain strong participles or participial adjectives, such as graven and laden. The verbs that remain strong but entered other classes are draw, slay, wake, and rarely, heave, when the preterite hove is used. The token frequency data from LAEME and CELEX are presented in Table 2.7. 47 Table 2.7: Class VI Token Frequencies PDE outcome S W S S S S S S W W W S W W W W W W W W W Verb stand fare take draw slay swear (for)sake8 wake wash heave laugh shake wade ache flay step gnaw grave bake shave lade LAEME frequency 1161 520 515 473 334 207 153 109 81 72 42 30 20 19 12 12 10 7 4 2 2 PDE outcome S S S W S W S W S W W W W W W S W W S W W Verb CELEX frequency take 35196 stand 13850 draw 4638 laugh 3058 shake 2359 wash 1768 wake 1325 step 1065 swear 585 bake 423 shave 249 heave 242 ache 221 wade 149 grave 89 slay 79 gnaw 79 fare 51 (for)sake 40 flay 26 lade 0 It is interesting to observe that the LAEME data do a better job of predicting the outcomes than the CELEX data. Slay provides another example of a verb that declined in frequency over time but retained strong inflection. In this respect it resembles smite and is unlike wreak and mete. In the case of slay, it retained a strong inflection that was not its inherited form, but rather was generated by analogy with Class VII verbs. Slay and Class VII verbs are discussed in section 2.7 of this chapter and at even greater length in Chapter 3. The two forms incorrectly predicted by LAEME token frequencies are fare and shake. Shake increased in frequency over time, and it resembles sake, take, and 48 wake. In PDE, the situation of shake and sake is reversed: it is now (for)sake that is of low frequency and dependent upon phonological similarity to retain its strong inflection. Bake and ache were not of sufficient frequency for even the phonological similarity with the other Class VI verbs to make their strong preterites salient. It is probable that bake was more frequent in the spoken language, being a homely activity, than in the written corpus. Even so, it is weak in PDE, and I have no explanation to offer other than low frequency. The pattern of Class VI verbs was somewhat productive in ME. Like take, quake also acquired a preterite from this class, although quook, used by Chaucer9 (MED s.v. quāken), has not survived. As for fare, it was of very high frequency in EME and is now of very low frequency in PDE. This alone might suffice to account for its weak outcome, but a further complicating factor contributed. The EME paradigm of fare was similar to the go ∼ went paradigm. Originally the preterite of wend, the highly frequent form went became disassociated from the paradigm of wend, which was infrequent in the present to the point of dying out. Having become detached from wend, went then attached itself to go. The result was a suppletive paradigm go ∼ went. Similarly, the highly frequent form ferde, originally the preterite of weak feran, became disassociated from the paradigm of that verb, whose present was already obsolescent in ME. Having become detached from feran, ferde attached itself to faran, which was properly a strong verb. The result was an irregular paradigm faran ∼ ferde. The irregularity was leveled out to fare ∼ fared by the 16th century (OED). The distribution of preterite and non-preterite forms of the strong and weak verbs in the LAEME corpus is shown in Table 2.8. The 490 non-preterite forms of faran and the 201 preterite forms of feran thus formed what would have been a suppletive paradigm were the roots of the two 49 Table 2.8: LAEME faran vs. feran Frequency faran (strong) feran (weak) # preterite forms 30 201 # non-preterite forms 490 0 verbs not ultimately the same. Already in OE, the preterite was weighted in favor of the weak verb. It is impossible to carry out an accurate search on the untagged complete OE corpus for the preterite singular, because of the fact that the preterite singular of strong faran, fōr, is homographic with the preposition for. However, a search of the preterite plurals fōron and ferdon, and a search of the preterite singulars fōr and ferde in the York-Toronto-Helsinki Parsed Corpus of OE Prose, reveal the imbalance. The distribution of preterite singular and plural forms of the strong and weak verbs in the tagged OE corpus is shown in Table 2.9. Table 2.9: Old English faran vs. feran Preterite Frequencies faran (strong) feran (weak) # preterite forms 694 1493 # non-preterite forms 201 499 In OE, as in EME, the preterite of the weak verb outnumbers the preterite of the strong verb. This distribution led to the pseudo-suppletive paradigm fare ∼ ferde in EME, which led to the weak paradigm fare ∼ fared in PDE. 50 2.7 Class VII Verbs Class VII verbs are divided into 7 subclasses by Krygier. For present purposes, however, it is most convenient to group VIIa-VIId together and call the result VIIa, and to group VIIe-VIIf as VIIb. Neither of the verbs from VIIg survives. Of VIIa, the verbs that did not undergo lexical loss and that survive into PDE are ban, beat, fall, fold, hang, hew, hold, leap, salt, shed, walk, wax. Salt may be from the strong verb sealtan, but may also have been from or influenced by the noun salt. Similarly, aFertig (2009) notes that ban may be from the OE strong verb bannan, the ON weak verb banna, and/or the noun ban. If the nouns played a role in their development, they would be a factor in making these verbs lose their strong preterites. Of VIIb, the verbs that did not undergo lexical loss and that survive into PDE are blow, crow, dread, flow, grow, know, let, low, mow, row, read, sow, sleep, throw. For details on the exclusion of claw from this list, see Chapter 3. Dread, read, and sleep had begun to develop weak forms already in OE. Read is synchronically strong in PDE, due to a regular phonological rule of vowel shortening. Let is synchronically a no-change verb, an inflection that is made possible by the final dental, but unlike most such verbs, is not from a shortened weak preterite. The OE ablaut was lǣtan ∼ lēt ∼ lēton ∼ lǣten. In ME, /æ:/ raised to /E:/. If normal phonology had applied, both would have undergone the Great Vowel Shift to /i:/, but a shortening of obscure origin applied first, resulting in /E/ for both present and preterite. See Welna (1996: 139) for a summary of accounts of the phonology, and the OED for possible parallels. Tables 2.10 and 2.11 present the token frequency data from LAEME and CELEX for Class VII verbs. 51 Table 2.10: Class VIIa Token Frequencies PDE outcome S S S W W W W W W W W W Verb hold fall hang wax beat leap shed walk fold hew ban salt LAEME frequency 1495 666 231 158 106 84 82 48 43 21 14 5 PDE outcome S W S S W W W W W W W W 52 Verb hold walk fall hang beat fold leap ban shed salt hew wax CELEX frequency 8644 5557 5341 2611 1553 847 549 362 274 72 18 0 Table 2.11: Class VIIb Token Frequencies PDE outcome S S W W W S W W S W S W W W S/W Verb LAEME frequency let 1139 know 328 dread 308 read 197 sleep 128 blow 84 sow 84 flow 44 grow 31 mow 26 throw 21 low 11 row 9 glow 9 crow 3 PDE outcome S S W S S W S W W W W W S/W W W Verb CELEX frequency know 38013 let 7728 read 6719 grow 6189 throw 2940 sleep 2317 blow 1509 glow 298 sow 225 flow 701 dread 154 mow 84 crow 54 row 57 low 0 Using the data from LAEME, the Class VIIa verbs behave in perfect accordance with the frequency hypothesis. Hold, fall, and hang, the three most frequent verbs, are strong, and the others are weak. Hang acquired hung by analogy with Class III verbs such as clung. The frequency of walk is much higher in CELEX than in LAEME, but its frequency did not increase early enough for the strong preterite to be preserved. Morever, it ends in a liquid + consonant cluster, like all the verbs of Class IIIb, which all became weak. As such, walk is treated further in Chapter 4. The verbs in Table 10 behave perfectly according to token frequency lines, with respect to each other. The high frequency of wax in LAEME might lead us to expect it to have retained its strong inflection, but in the first place, it has little phonological similarity to other verbs. Furthermore, wax declined in frequency as grow began to replace it in meaning, which no doubt contributed to 53 its decline. See section 2.8 below for changes in frequency over time. In contrast, the verbs of subclass VIIb do not behave according to token frequency. Read and dread are omitted, because they were partially weak already in OE, and weak forms dominated in ME. Neither has any strong preterites in the LAEME corpus, despite a high overall token frequency (see Appendix 2). Sleep is similar to read and dread in acquiring weak preterites in OE, but its strong preterite was more robust than theirs in ME. The OED admits the possibility that beside strong slǣpan there was an unattested weak causative *slǣpan, identical in infinitive, to which the weak preterites were formed. Furthermore, the form slept was reinforced by such preterites as crept, wept, kept, swept, and leapt, which no doubt contributed to its dominance over the strong preterite. The verbs that end in -ow, e.g. know, grow, sow, underwent a great deal of change in frequency between EME and PDE, as Table 11 shows. Grow and throw increased substantially in frequency, and sow and mow decreased. The frequency data from CELEX correlate better with the inflectional outcomes than the frequency data from LAEME, but the match is still not good. These verbs warrant a separate treatment, which is given in Chapter 3. 2.8 Longitudinal Studies The relative frequencies of most strong verbs did not change significantly between EME and PDE. Some verbs, however, underwent an identifiable change in frequency. For verbs that changed in frequency, there are four possible categories into which they could fall, combining the two factors of strong or weak outcome and increase or decrease of frequency. This section traces the frequencies of one 54 verb in each category over time, using counts gathered from the historical corpora. Smite is used as the example of a verb that declined in frequency over time, yet remains strong.10 Wax is used as the example of a verb that declined in frequency over time and lost its strong inflection. Walk is used as the example of a verb that increased in frequency over time, yet failed to preserve its strong inflection. Grow is used as the example of a verb that increased in frequency over time and remains strong. The development of the frequencies of these verbs are depicted numerically in Tables 12 through 15, and graphically in Table 16. Because of the difficulty in obtaining all possible verbal forms for corpora other than LAEME and CELEX, the numbers represent the combined number of hits for the four principal parts: infinitive, preterite singular, preterite plural, and past participle. In later periods, the second and third fall together. The final row is calculated by dividing the frequency for wax by the size of the corpus and multiplying by 100 to obtain a percentage. The OE counts are taken from the Dictionary of Old English Corpus, which contains all extant OE texts. The EME counts are taken from the LAEME corpus. The LME counts are taken from the Penn-Helsinki Parsed Corpus of Middle English, combining the two periods called M3 and M4 by the creators of the corpus. The EMnE counts are taken from the Penn-Helsinki Parsed Corpus of Early Modern English, combining the three periods called E1, E2, and E3. The PDE counts are taken from the CELEX corpus. Some of the fluctuations between adjacent periods are no doubt due to chance. The frequency hypothesis suggests that low frequency verbs that increased their frequency earlier would be more likely to retain their strong inflection than low frequency verbs that increased their frequency later. Similarly, high frequency verbs that declined in frequency earlier would be more likely to lose their strong 55 inflection that high frequency verbs that declined in frequency later. Thus, we would expect to see earlier changes in wax and grow than in smite and walk. What we find is a climb in frequency for smite during the ME period, and then a gradual decline. Wax indeed declined earlier, and dropped nearly out of existence in EMnE. The later decline in frequency of smite accords well with the fact that it preserved its inflection. In contrast, walk and grow both emerge from obscurity in the middle of the ME period, and increase notably in EMnE. One preserves its strong inflection, and the other does not. The sample longitudinal studies in changes of frequency support the notion that while token frequency is important, more factors than token frequency are at work. Verbs whose change in frequency parallel each other have opposite inflectional outcomes. In both cases, the conservative verbs, smite and grow, have support from sizable families including verbs such as write and blow, whereas the verbs that lost their inflection, wax and walk, are more morphologically isolated. These results provide further support for the idea that a complete, in-depth study of the frequencies of each verb in each historical period would not gain us further explanatory power. 56 Table 2.12: Frequency of smite OE smite Corpus ratio * 100 EME 1150-1325 115 99 3,000,000 650,000 .004 .015 LME 1350-1500 131 727877 .018 EMnE 1500-1710 11 821647 .001 PDE 58 18,000,000 .0003 Table 2.13: Frequency of wax OE wax Corpus ratio * 100 EME 1150-1325 259 94 3,000,000 650,000 .009 .014 LME 1350-1500 23 727877 .003 EMnE 1500-1710 12 821647 .001 PDE 0 18,000,000 0 Table 2.14: Frequency of walk OE walk Corpus ratio * 100 EME 1150-1325 9 14 3,000,000 650,000 .0003 .002 LME 1350-1500 24 727877 .003 57 EMnE 1500-1710 127 821647 .015 PDE 5557 18,000,000 .031 Table 2.15: Frequency of grow OE grow Corpus ratio * 100 EME 1150-1325 28 19 3,000,000 650,000 .001 .003 LME 1350-1500 32 727877 .004 EMnE 1500-1710 120 821647 .015 Table 2.16: Longitudinal Frequencies 58 PDE 6189 18,000,000 .034 2.9 Conclusions In this chapter, the frequency hypothesis was tested, to determine whether verbs of higher frequency were more likely to remain strong than verbs of lower frequency. Cases where the frequency hypothesis does not predict the behavior of the verbs were identified as areas for the rest of the dissertation to explore. Class I verbs are predictable according to the frequency hypothesis and have a 50% rate of preservation of strong inflection. Class II verbs are less predictable and have a preservation rate of only 17%. The low rate of survival is attributed to the low phonological coherence among verbs, which bore little resemblance to each other in comparison with Class I verbs. Moreover, three verbs, bid, cleave, and dive, became confused with other verbs of similar semantics and phonology, resulting in variation in the morphology that persists into PDE. Class II verbs illustrate the importance of phonological similarity for preservation of strong inflection. Class IIIa verbs, the sing ∼ sang ∼ sung and cling ∼ clung type, also illustrated the importance of phonological similarity for preservation. Every verb that bore a resemblance to the others—all, in other words, besides burn and climb—remained strong, while burn and climb became weak. Class IIIa verbs are addressed in Chapter 3. Class IIIb verbs, which end in a liquid + consonant cluster, present a crux. All verbs of this subclass, even ones of high frequency, such as help, became weak. A solution for this crux is offered in Chapter 4. Class IIIc verbs, namely fight, braid, and thresh, behave according to the frequency hypothesis. Class IV and V verbs behave largely according to the frequency hypothesis, if CELEX frequencies rather than LAEME frequencies are used. In contrast, Class VI verbs are better predicted according to the LAEME frequencies. Class VIIa verbs are entirely predictable by LAEME frequencies, and except for walk, by CELEX fre- 59 quencies. Class VIIb verbs, especially those with preterites ending in <=ew>, are predictable by CELEX frequencies and remarkably unpredictable by LAEME frequencies. Chapter 3 addresses the importance of phonological similarity for the verbs with <-ew> preterites, especially in earlier stages of English, but with continuing effects even in PDE. For the overall effectiveness of token frequency and class membership, Chapter 6 contains the quantitative analyses of the results obtained in the dissertation. It is there demonstrated that the frequency hypothesis, while not explaining all of the data, is the single factor with the most explanatory power for the inflectional outcomes of the strong verbs. 60 Chapter 3 Cue Validity 3.1 Introduction When we consider the impact of some phonological feature on the morphological outcome of a verb, there are two ways in which this feature may be important. There may be some inherent property of this feature that favors a strong or weak outcome, in which case we give a functional account. Or the feature may have become associated with a particular inflection through an accident of the language, in which case we give a distributional account. In most cases, both make themselves felt to different degrees. This chapter concentrates on distributional accounts, with functional accounts playing a secondary role. The following chapter contains examples of functional accounts where distributional phonological features play a secondary role. Distributional accounts of linguistic phenomena can be derived from more basic facts about cognitive processes. Building on Wittgenstein’s (1953) theory of categories, Beach (1964) and Rosch and Mervis (1975) developed the concept of 61 cue validity to describe the relationship between features and categories. The idea behind cue validity is that members of a category, such as a strong verb class, need not all share identical features, nor need the features that they share be unique to that category. Not all birds have wings, nor are all winged objects birds. The greater the probability that a feature does belong to a category, the more quickly the presence of that feature will lead to identification of that category. For example, the presence of wings will more quickly lead to the identification of an object as a bird than the presence of eyes will. Rosch and Mervis (1975: 575) define cue validity as a measure of the probability of feature X occurring in category Y, calculated using the equation in (1). (1) Cue validity formula #X ∈ Y #X In our example of birds and wings, the cue validity of wings for identifying birds is the number of winged birds divided by the number of winged objects. As a hypothetical example, imagine that all dental-final words in English were preterites. The cue validity of the feature “dental-final” for the category “preterite” would be 1, the maximum possible. If a speaker heard a word ending in a dental, s/he would immediately know the word was a weak preterite. Identification of the word as preterite would proceed much faster than if the word ended in some consonant not exclusive to the preterite. As it is, not all dental-final words in English are weak preterites, but a word that ends in a dental stop stands a good chance of being a dental preterite.11 In this chapter, two sets of verbs are studied in terms of cue validity. First, the verbs from Old English (OE) Class III that ended in nasal or a nasal plus a velar. This class is the source of Present Day English (PDE) verbs such as sing 62 and swim. Second, the verbs that take a preterite that ends in <-ew>, such as know and grow. The presence or absence of an initial consonant cluster is a feature relevant to both categories, and the presence or absence of final nasals, velars, and the sequence <-ung>, are relevant to the Class III verbs. 3.2 Velar- and Nasal-Final Verbs The set of Class III verbs ending in nasals and velars, such as sing ∼ sang ∼ sung, has been well studied. An important work is Bybee and Moder (1983), which draws on the concepts, discussed above, of natural categories, developed by Wittgenstein, Beach, and Rosch and Mervis. They describe Class III verbs in terms of natural categories. In a theory of natural categories, there are several characteristic features shared among the verbs, so that each verb has at least one characteristic feature in common with at least one other member of the set, and many verbs share multiple features with other verbs. For example, all members of this class end in either a nasal or a velar, and many verbs end in a velar nasal, e.g. sing, or a nasal followed a velar stop, e.g. shrink. A member that has most or all of the features is a prototypical member. Other members may be fuzzier and share fewer similarities. The approach using natural categories is in contrast to an approach that seeks to define a class by means of defining features whose presence is mandatory for all members. 3.2.1 History of Velar- and Nasal-Final Verbs Here follows a description of the philological history of these verbs. In OE, they conjugated according to the ablaut pattern shown in Table 3.1. In OE, Class 63 III verbs stems could be described as ending in any nasal + consonant sequence, including a geminate nasal. Following Homorganic Cluster Lengthening in Middle English (ME), Class III split in two, with -nd verbs forming a subclass distinct from the rest. Also in Early Middle English (EME), degemination applied to the geminate nasals. Of the verbs ending in nasals plus labial stops, there were four in OE. Two, cimban ‘join’ and hrimpan ‘frown’, did not survive into ME. A third, climban ‘climb’, also underwent HCL. That left hlimpan (ME limpen) ‘befall’ as the sole member of this class with a final labial stop. It underwent lexical loss in the fifteenth century. The verb stems could then be described as ending in a nasal or a nasal + velar, with the single exception of limpen. In Early Modern English (EMnE), the phonemicization of the velar nasal took place. This development had the potential to result in a class described as exclusively nasalfinal, but the sing pattern was extended to verbs, such as dig, that ended in a velar stop, with no nasal. Since EMnE, members of the class have ended in a nasal, or a velar, and most often a velar nasal. Bybee and Moder (1983: 143) emphasize the important role of the phonological similarities in making this a highly productive class, in contrast to classes where verbs of a greater variety of final consonants were admitted, e.g. speak, weave, tear. Table 3.1: Old English Class III Inflection sing Infinitive Pret. Sg singan sang Pret. Pl. sungon Past. Part. sungen During ME, speakers began to employ the vocalism of the past participle and preterite plural in the preterite singular for many strong verbs, with the result that the original vocalism of the preterite was lost for approximately half of the sing-cling verbs, leaving an ablaut pattern with only two grades. Table 3.2 shows 64 the inflection of the verbs according to the American Heritage Dictionary (AHD), with column 1 containing verbs for which the dictionary records a preterite in /a/, and column 3 those verbs for only a preterite in /2/ is given. The former are referred to as tri-alternate, and the latter as bi-alternate. Columns 2 and 4 show the earliest century of attestation for a preterite in /2/ for each verb.12 The dates of attestation are taken from the Oxford English Dictionary (OED) and Middle English Dictionary (MED). For many readers, the classification of verbs into bi-alternate and tri-alternate will differ from that given in Table 3.2, for the reduction of grades is still an ongoing process. For example, there are speakers for whom the only possible past tense of spring is sprung, etc. Krygier (1994) presents a comprehensive picture of the strong verbs in OE and each century of ME, indicating which verbs are attested in what period, and how their present tense was formed. In a search of Krygier (255-67), I found only two verbs ending in nasals and velars that are attested throughout ME but were subject to lexical loss before PDE. These verbs are swinken ’work, strive’ and thringen ’press, crowd’. Unfortunately, due to the great variation in vocalism of all verbs, it is difficult to speak of a bi-alternate or tri-alternate “outcome” in the PDE standard dialect. Even the verbs classified as tri-alternate in the dictionaries, as listed in Table 3.2, have a long history of u-grade preterite singulars, many of which are the only possible preterites in the dialects of Present Day speakers. Therefore, it is impossible to define an outcome for swink and thring without PDE attestations, and they cannot be used in Tables 3.2 and 3.3 for calculations of bi-alternate and tri-alternate categories. In addition to the verbs in Table 3.2, which inherited the inflectional pattern of OE Class III, there exist also verbs that obtained this pattern by analogical 65 Table 3.2: Bi-alternate and Tri-alternate Tri-alternate begin ∼ began ∼ begun drink ∼ drank ∼ drunk run ∼ ran ∼ run shrink ∼ shrank ∼ shrunk sink ∼ sank ∼ sunk sing ∼ sang ∼ sung spring ∼ sprang ∼ sprung stink ∼ stank ∼ stunk swim ∼ swam ∼ swum Date of p.sg. <ung> attestation 16th 16th none 17th 17th 16th 16th 17th none Bi-alternate cling ∼ clung sling ∼ slung slink ∼ slunk spin ∼ spun sting ∼ stung swing ∼ swung wring ∼ wrung win ∼ won13 Date of p.sg. <ung> attestation 16th 17th 17th none 16th 18th 14th none extension. Table 3.3 presents the data for such verbs as are listed in the AHD. Some verbs, such as drag, have the Class III inflection only in nonstandard use and have not yet made it to the dictionary. See the Dictionary of American Regional English and Bybee and Moder (1983) for other examples. Column 2 lists the etymological source of each verb. Column 3 lists the earliest dates of attestation for an <-a-> or <-o-> preterite, if any. In every case but ring, the preterite in /a/ never caught on, and the PDE preterite is thus homophonous with the past participle in /2/. Columns 4 and 5 list the earliest dates of attestation for the <-u-> preterite and past participle. Dates of attestation are taken from the OED and MED. Two aspects of the verbs with Class III inflection require explanation. First, which verbs reduced such that the dictionaries no longer list a past tense with an a-grade? Second, why did verbs reduce in favor of the u-grade rather than the a-grade (cf. Bybee and Slobin 1982: 117)? 66 Table 3.3: Analogically Extended Verbs Verb Source <a, o> preterite dig ∼ dug fling ∼ flung hang ∼ hung15 OF diguer ON 14th Class VII hōn weak hangian ON hengian ring ∼ rang ∼ rung denominal 13th stick ∼ stuck weak stician Class V stecan strike ∼ struck Class I strı̄can string ∼ strung denominal <u> preterite <u> past participle 18th 16th ∼15th14 17th 15th 15th 15th 16th 13th 16th 17th 17th 16th 17th The answer to the first question follows the predictions of the frequency hypothesis. Low-frequency verbs were more likely to lose their a-grade preterite. Verbs that bore a strong phonological resemblance to these low-frequency verbs were also likely to reduce. Table 3.4 shows the EME token frequency of the trialternate verbs that did not reduce in the standard dialect. Column 2 records the number of hits for the preterite first and third singular, where the a-grade is expected. Column 3 records the number of hits for the preterite plural and second singular, and the past participle, where the u-grade is expected. Table 3.5 shows the same data for the alternate verbs that did reduce to bi-alternate and that have only two grades recorded in the AHD. The frequencies are taken from the Linguistic Atlas of Early Middle English (LAEME). The frequency hypothesis predicts that the bi-alternate verbs should be, on average, less frequent than the tri-alternate verbs. Tables 3.4 and 3.5 support this hypothesis. The intuitive appraisal of the difference in the relative frequencies 67 Table 3.4: Tri-alternate LAEME Frequencies Tri-alternate verbs (be)gin ∼ (be)gan ∼ (be)gun drink ∼ drank ∼ drunk run ∼ ran ∼ run shrink ∼ shrank ∼ shrunk sink ∼ sank ∼ sunk sing ∼ sang ∼ sung spring ∼ sprang ∼ sprung stink ∼ stank ∼ stunk swim ∼ swam ∼ swum Total (without (be)gin) Average (without (be)gin) 1st, 3rd Pret. sg.

The re-randomization tests the hypothesis that the distribution of the frequencies over the two groups, bi-alternate and tri-alternate, is not random. It does this by redistributing the frequencies at random 10,000 times, creating 10,000 different samples to compare the observed data to. For the hypothesis that the distribution of Tables 3.4 and 3.5 is non-random, and the high frequency verbs are indeed more likely to be bi-alternate, the re-randomization test gives a p-value of less than 0.0001. The statistical analysis supports the hypothesis that the more frequent verbs were more conservative in their morphology. In terms of phonological features, the bi-alternate verbs are rather coherent, as noted by Bybee and Moder (1983) for PDE. All the verbs of the bi-alternate set, with the exception of win, are alike in having an initial consonant cluster. Of the 68 Table 3.5: Bi-alternate LAEME Frequencies Bi-alternate cling ∼ clung sling ∼ slung slink ∼ slunk spin ∼ spun sting ∼ stung swing ∼ swung wring ∼ wrung win ∼ won Total Average Expected a-grade 0 0 0 0 5 2 15 38 60 Expected u-grade Total 3 3 2 2 0 0 1 1 19 24 0 2 4 19 34 72 63 123 13.7 8 verbs, 5 end in <-ng>, whereas only 2 tri-alternate verbs end in <-ng>. In the tri-alternate set, only one verb, spring, has both the initial cluster and the <ng>, and its frequency of 43 nearly equals the combined frequency of the 5 bi-alternate verbs ending in <-ng>—cling, sling, sting, swing, wring—which total 50. In other words, the high token frequency of spring overrode its phonological similarity to the other verbs, thus causing it to remain conservatively tri-alternate. Spin is bi-alternate in American English, with span absent from the American Heritage Dictionary, but tri-alternate in British English, with span present in the Oxford Advanced Learner’s Dictionary. Welna records span as a form lasting in American English until the 19th century. I conclude that the low token frequency of spin is what caused it to reduce eventually, but its failure to end in a velar is what caused it to be conservative so long. The high frequency of win, combined with its lack of initial cluster and its lack of a final velar, leaves its reduction completely unexpected. The answer is perhaps to be sought in a sporadic rounding and raising effect of the initial /w/, such as 69 occurred in its homophone one, which ought to rhyme with alone (OED s.v. one). The remaining bi-alternate verb to be explained is slink. It resembles shrink closely in phonological structure as well as in its LAEME frequency, which leads one to wonder why its only possible preterite is slunk, while shrink retains shrank alongside innovative shrunk. Both slink and shrink are unattested in the LAEME corpus; however, it is likely that they were not equally infrequent, but that this apparent similarity in frequency is an accident of the generally low attestation of these verbs in LAEME. For PDE, the CELEX corpus (Baayen et al. 1995) gives a noticeably higher frequency for shrink (364) than for slink (30). A search of Early English Books Online gives a similar disparity: 4340 hits for shrink and only 181 for slink. It is therefore to be concluded that in ME and EMnE shrink was more frequent than slink, as is the case in PDE. The frequency difference explains the PDE outcome shrank—which, nevertheless many PDE speakers do not use; cf. “Honey I Shrunk the Kids”—alongside slunk. In addition, Bybee and Moder (1983: 134) find that one feature of this class in PDE is that the first consonant of the cluster is /s/ in nine of their eighteen verbs. It may be the case, seeing that /s/ is the first consonant of the cluster in 5 of the 8 bi-alternate verbs in Table 3.5, that not beginning with /s/ was another factor that weighed against shrink. The fact that wring appears from Table 3.3 to have begun reducing earlier than the rest, when it has the highest frequency of the bi-alternate verbs, is contrary to what we expect and to a general tendency observed here: that verbs of higher frequency are more conservative in their inflection than those of lower frequency. Furthermore, most of the verbs in Table 3.5, which became bi-alternate, are completely unattested in the preterite in the LAEME corpus. These two facts lead me to believe that behind the scenes, outside of the extant written corpus, several 70 of the other verbs began reducing before wring, and it was their influence that helped contribute to the reduction of the higher frequency wring. In other words, because wrung as a past tense is first attested in the 14th century, slung, clung, thrung, stung, swung were probably in the spoken language prior to that, despite their absence from the written record until the 16th and 17th centuries. Of the verbs that were added to this class subsequent to OE, Bybee and Moder (1983: 141-42) note that only one, ring, is tri-alternate in PDE. Table 3.3 shows that it was also the earliest of the verbs to be added to this class, being present in the language by the 13th century. The inflection of ring shows that at this early date, even if reduction had already begun, the tri-alternate inflection was still productive. In addition, fling, though bi-alternate in PDE, illustrates the productivity of the tri-alternate inflection in ME. Having joined the Class III verbs, it behaved like other low-frequency verbs beginning with a consonant cluster and ending in <-ng> by becoming bi-alternate. Verbs such as string, strike, dig, and stick, which did not join this class until later, after ring and fling, received bi-alternate inflections from the start. They began to appear in EMnE, around the same time that bi-alternate inflections began to appear in the written record, having, according to my supposition, been in the spoken language since the first half of ME. 3.2.2 Loss of -ang Having examined the distribution of verbs according to whether they are bialternate or tri-alternate in PDE, and having seen that most of their outcomes were determined by a combination of token frequency and phonological similarity, we can now turn our attention to the question of why, when the reduction took 71 place, it was in favor of the u-grade rather than the a-grade. One consideration may have been that the u-grade occurred in both the preterite plural and the past participle—in other words, in half of the four principal parts. One could posit that it was less disruptive to the paradigm to change one principal part as opposed to two. This phenomenon would be a form of intra-paradigmatic leveling. However, other strong verbs show that even if the number of principal parts was a factor, it could not have been the whole story. OE Class IV strong verbs inflected according to the pattern in Table 3.6. Like many sing-cling verbs, they lost the vowel of their preterite in favor of the vowel of the past participle, arriving at the paradigm shown in the table. Table 3.6: Class IV Strong Verbs OE PDE Infinitive Pret. sg. beran bær bear bore Pret. pl. bǣron bore Participle boren born(e) The preterites of these classes had vowels of the same quality, namely /æ/, in the singular and plural. Yet instead of extending the /æ/ of these two principal parts to the participle, the participial vowel /O:/ was extended to both principal parts of the preterite, in spite of the greater paradigmatic changes required. If type frequency, in terms of number of principal parts with a given vowel, is not the answer, the next logical place to turn is token frequency. The first hypothesis to test whether the u-grade forms simply outnumbered the a-grade forms, and the a-grade forms began to die out. The token frequencies from Table 3.7 show why this hypothesis cannot hold the explanation either. It is true that there is a difference between the percentage of u-grade forms of tri-alternate verbs and those of bi-alternate verbs. However, whether or not we 72 Table 3.7: Bi-alternate vs. Tri-alternate Frequency a-forms u-forms 602 274 113 94 Tri-alternate Tri-alternate (without (be)gan) Bi-alternate 60 63 % u-forms 31% 45% 51% take the unusually frequent (be)gan into consideration, the 51% ratio of u-grade forms to a-grade forms for the verbs that reduced is certainly not enough to explain why the original preterite vocalism was lost. If type frequency and token frequency are not sufficient to explain why cling ∼ clang ∼ clung reduced to cling ∼ clung ∼ clung rather than cling ∼ clang ∼ clang, we must turn elsewhere. In discussing the reasons for the productivity of the singcling class relative to other strong verb patterns, such as classes I and II, Bybee and Moder (1983) propose cue validity as one possible factor. They point to the paucity of PDE words ending in /ung/ or /unk/ outside of Class III verbs, which means that the features word-final /ung/ and word-final /unk/ correlate well with the category of past tense. If this cue validity contributed to the productivity of these verbs, then it may well also have contributed to the survival of clung. I quantify their hypothesis by comparing the distribution of the word-final sequences in ME. The orthographic sequences <ung>, <ang>, <unk>, and <ank> were gathered from LAEME. Instances of the sequence <ong> were added to the count for <ung> when tongue and young were spelled with <o>; likewise for <onk> in monk. In principle, because the sequence <on> may represent a pronunciation /un/, instances of <ong> and <onk> in the preterite singular of strong verbs may represent an analogical extension of <ung>/<unk> from the 73 preterite plural and past participle. I do not include them, because while <an> and <on> are both used for the preterite singular in LAEME, <un> is never used. It is unlikely, though not impossible, that if the spelling <un> was used to represent /un/ in the preterite plural and past participle, it was never used in the preterite singular if /un/ was indeed the pronunciation. Free variation between <un> and <on> would be expected. It is more likely that <on> in the preterite singular always represents [On]—the allophone of /an/—and never /un/ in the LAEME corpus. Instances of <on> in strong preterite singulars are therefore not included. The goal is to compute whether /ung/ in ME had higher a cue validity for preterites than /ang/ did. Using LAEME, the number of ung-final words is compared to the number of ang-final words. Because of the great confusion in spelling and allophony between /an/ and /on/, the search for ang-final forms was conducted on lemmas ending in <-ang> and <-ong> and forms ending in <-ang>. A total of 112 hits was obtained. The search for ung-final forms was conducted on forms ending in <-ung>, and a total of 78 hits was obtained. In all cases, forms with more than one syllable have been ignored. The number of preterites was obtained by searching for all strong preterite first and third singular forms of verbs with -ng- in the lemma. A total of 90 hits was obtained. If all 90 preterites were ang-final, the cue validity of /ang/ for strong preterites would be 90/(90+112) = 44.5%. If all 90 preterites were ung-final, the cue validity of /ung/ for strong preterites would be 90/(90+78) = 54%. The same searches were carried out for /ank/ and /unk/ words, obtaining 5 ank-final words, 1 unk-final word, and 28 preterite first and third singulars for verbs ending in -nk. The figures are presented in Table 3.8. 74 Table 3.8: LAEME Cue Validity an(g/k)-final Non-preterites 112 (-ang) 5 (-ank) Potential Preterites 90 (-ang) 28 (-ank) Total 235 Cue validity 50.00% un(g/k)-final 78 (-ung) 1 (-unk) 90 (-ung) 28 (-unk) 197 60.00% A one-tailed z-test for two sample proportions is appropriate, because it was anticipated that the proportion in the third column would be greater than the proportion of the second column. The z-value obtained is 2.09, which gives a p-value of less than .02. These calculations support Bybee’s hypothesis that at the time the verbs began to reduce their inflection in favor of /ung/ throughout, the feature /ung/ and /unk/ had a higher potential cue validity for the category strong past tense than /ang/ and /ank/. When an /ung/ or /unk/ preterite was heard, it was less likely to be confused with an adjective, noun, present tense verb, or other category. As use of /ung/ and /unk/ preterites increased, the greater recognizability of these forms as past tenses facilitated communication among speakers. The sing-cling class of verbs have presented cases where the frequency hypothesis makes the correct predictions and cases where it does not. In cases where the frequency hypothesis was inadequate to explain the data, the behavior was attributed to the effects of word structure, namely the presence of an initial consonant cluster, the presence of an initial /s/, and the presence of a final sequence in -ung, -ang, -unk, or -ank. Verbs similar in phonological structure tended to 75 behave similarly. The effects were twofold. Low frequency verbs, such as slink, retained their strong inflection beyond what the frequency hypothesis would predict. Higher frequency verbs that ended in -ng were more likely to reduce from three principal parts to two, if they were phonologically similar to the low frequency verbs that reduced, most of which ended in -ng, and began with a cluster, especially one beginning with /s/. These structural similarities account for the reduction in verbs such as wring and sting, when the frequency hypothesis alone would predict that they remain tri-alternate. Phonological structure is also argued to have played a role in the selection of -ung over -ang as the past tense for sing-cling verbs. Preterites that ended in -ung and -unk were more distinctly recognizable as preterites, for they had higher cue validity. The higher cue validity results from the interaction of frequency and word structure. These phenomena in the sing-cling class are used as supporting evidence for the hypotheses about the behavior of the <-ew> verbs in section 3.3. 3.3 The <-ew> Verbs In OE, verbs with preterites in <-ēow> belonged to Class VII (Krygier 1994), divided approximately evenly between verbs with infinitives in <-āwan> and those with infinitives in <-ōwan>, in addition to an isolated verb hēawan ‘hew’. Table 3.9 shows the OE ablaut patterns. Table 3.9: Class VII <-ēow> Preterites know bloom hew Infinitive cnāwan blōwan hēawan Pret. Sg cnēow blēow hēow 76 Pret. Pl. cnēowon blēowon hēowon Past. Part. cnāwen blōwen hēawen Like cnāwan were conjugated blāwan ‘blow’, clāwan ‘claw’, crāwan ‘crow’, māwan ‘mow’, rāwan ‘divide’, sāwan ‘sow’, ðrāwan ‘throw, curl’, wāwan ‘blow’. Like blōwan were conjugated flōwan ‘flow’, glōwan ‘glow’, grōwan ‘grow’, hlōwan ‘bellow’, rōwan ‘row’, snōwan ‘hasten’, spōwan ‘succeed’. The following phonological changes, chronologically ordered, affected the verbs of this type. • (1) /o:w/ and /a:w/ > /Ou/ • (2) /eow/ <ēow> > /eu/, • (3) /æaw/ <ēaw> > /Eu/. • (4) /eu/ > /iu/ • (5) /iu/ and /Eu/ > /ju/ Changes 1-3 occurred by about 1250, except in the north (Lass 1992: 50-51). Change 4 occurred in later ME (ibid.), and change 5 occurred in the 16th (Welna 1996: 196) or 17th century (Lass 1999: 98-102). The morphological result of these changes is that cnāwan ‘know’ and blōwan ‘blow’ conjugated identically from ME on, except in the north, where the two classes remained distinct. Outside of the north, the only verb to retain a conjugation distinct from the others was hēawan ‘hew’. Table 3.3 shows the ME ablaut patterns circa 1300. As in other instances in this study, I eliminate the following verbs from consideration: rāwan ‘divide’, wāwan ‘blow’, and spōwan ‘succeed’, which are not attested after OE, according to the OED, MED, and Krygier (266-267); and clāwan, because the OED finds it doubtful that the PDE verb claw is descended directly 77 Table 3.10: ME Principal parts Infinitive know knOu@n blow blOu@n hew hEu@n Pret. sg. kneu bleu heu Pret. pl. kneu@n bleu@n heu@n Participle knOu@n blOu@n hEu@n from the OE strong verb. Were clāwen the source of PDE claw, the expected infinitive would be the unattested clow*. It is more likely that weak clawian is the source, and that the strong preterite clew, found in the 14th and 15th centuries, was an analogy that failed to catch on, rather than a direct reflex of clēow. As we shall see later, <-ew> preterites were analogically extended to several verbs during the 14th and 15th centuries. Some of these analogous <-ew> preterites were retained into PDE, while others fell out of use. Additionally, analogical clew has continued to arise independently in various dialects, even after ME, according to the OED. The remaining verbs to be considered are thus blow, crow, flow, glow, grow, hew, low, mow, row, sow, and throw. 3.3.1 Token Frequency Previous works on the strong verbs, including Hooper (1976), Hare and Elman (1995), Lieberman et al. (2007), have treated the relative frequencies of English verbs as constant over time. The implication is that any sufficiently large corpus from any period during the history of English can be used to gather the frequency data for a study of the history of English verbs. For most verbs, my own research has confirmed this overall stability of frequencies. However, tables 3.11 through 3.13 show that the relative frequencies of the <-ew> verbs changed significantly 78 over time. Table 3.11 presents the verbs sorted by the token frequency of their preterite singular, their preterite, and the sum of their four principal parts. The frequency searches were carried out on the Dictionary of Old English Corpus, which contains the entire extant OE corpus. Due to the untagged nature of the corpus, it was not practical to search for all possible inflected forms in which a verb could occur, and to disambiguate all possible homographic forms manually. For this reason, the four principal parts were used as search queries. Table 3.12 presents the frequencies from LAEME, with searches carried out both for all preterite forms, and for all instances of the verb. Table 3.13 presents the PDE frequencies taken from the CELEX database. Here, the total for all instances of the verbs is given. The total is given for PDE verbs, whereas the total plus individual parts are given for earlier stages, because the earlier stages present such a poor fit between outcome and frequency. Without the breakdown into parts, it could be argued that it is not the frequency of the verb as a whole that matters, but the frequency of the preterite. Including these data allows us to see that the frequency of the preterite at early stages does not do an adequate job of predicting outcome either. From Tables 3.11 and 3.12, it can be seen that OE and EME frequencies do a poor job of predicting PDE outcome. Grow, crow, and throw have remarkably low frequencies given their strong outcome, and flow and sow have remarkably high frequencies given their weak outcome. The PDE frequencies in Table 3.13 correlate with inflectional outcome much more closely, leaving only the retention of a strong crew16 unexplained. The increase in frequency of grow and throw as they began to acquire the semantics of wax and warp respectively, no doubt played a role in the survival of 79 Table 3.11: OE Frequencies Preterite sg.

However, not only must the survival of crew be accounted for, so must the fact that grow and throw did not lose their strong inflection when they were still relatively infrequent. To develop an explanation for the unexpected survival of strong inflection, the following section considers cases of analogical extension of the <-ew> preterite. The following section shows how these analogical extensions are parallel to some of the cases of unexpected survival. 3.3.2 Spread of <-ew> Preterites In the 14th century, <-ew> preterites began to spread to other verbs, both weak verbs and strong verbs of other classes. The vowel of the present tense was not a criterion for the analogy, for <-ew> preterites were formed both to presents with /Ou/ and to presents with other vowels, such as slay. The latter type is 80 Table 3.12: EME Frequencies LAEME pret. sg. know 23 know blow 14 sow sow 9 blow grow 6 grow flow 5 flow hew 3 hew throw 3 throw low 1 mow crow 0 low glow 0 row mow 0 glow row 0 crow LAEME pret. 47 26 23 9 7 7 3 2 1 1 0 0 LAEME total know 349 blow 86 sow 85 flow 45 grow 31 mow 26 throw 21 hew 20 low 11 row 10 glow 9 crow 3 explained by Bybee and Slobin (1982: 103) with reference to a product-oriented schema, a concept developed by Bybee and explained in detail in the introduction. This particular schema specifies a past tense with an initial consonant cluster, an <-ew> nucleus, and no coda. PDE, as noted by Bybee and Slobin, retains the product-oriented schema in the diversity of presents with <-ew> preterites: blow, fly, slay, draw. The criteria for membership, explained by Bybee and Slobin as a productoriented schema, can be fit into a source-oriented rule as well, specifying that the vowel of a verb beginning with a consonant cluster is changed to <-ew> in the preterite, if the vowel lies at the word boundary. The morphological rule is given in (2). (2) Generating <-ew> preterites V → ew / CC__# 81 Table 3.13: PDE Frequencies CELEX know grow throw blow flow glow sow mow row crow low hew total 38013 6112 2858 1507 616 298 225 84 74 54 51 18 One such verb that acquired an <-ew> preterite in the 14th century was snouen, which was formed from the noun snou and came to replace the inherited OE verb snīwan. The editors of the OED and MED agree that it acquired a preterite snew by analogy with the original <-ew> verbs from Class VII. It was the presence of the initial consonant cluster, according to my hypothesis, that qualified it for membership among the <-ew> preterites. The strong preterite is attested sporadically until the 19th century, but eventually lost out to the competing preterite snowed. Also in the 14th century, draw acquired the past tense drew by analogy with the Class VII verbs (Welna 1996: 135-6). The first point to notice is that it too has an initial consonant cluster. The second point to notice is that the vowel of the infinitive drauen, /au/, does not match the vowel of blouen, /Ou/. For this reason, the OED says that the analogy took place in the north. In the north, as stated in section 3.3, the sound changes that resulted in the ME diphthongal 82 system did not take place. The verbs that in OE had a stem in /a:w/ did not shift to /Ou/ and merge with the verbs that originally had a stem in /o:w/, as they did in the south, but remained distinct. Instead, /a:w/ became /au/. In the north, therefore, the diphthongs of the infinitives drauen and blauen would have been identical, allowing for the following analogy: blauen : bleu :: drauen : dreu.17 The same analogy occurred in gnaw, which was still pronounced with an initial /gn/ in ME. Gnaw, like draw, qualified for an <-ew> preterite by reason of its initial consonant cluster. This form gnew was current during the 14th through 16th centuries, although it eventually lost in favor of the weak gnawed, with which it was already competing in the 14th century (OED). Similarly, in the 14th and 15th centuries, clew is attested as a preterite for claw, which derives from the OE weak verb clawian (OED). In the south of England, after the merger of /a:w/ and /o:w/, all verbs with <-ew> preterites had the same vowel in the infinitive–and thereby in the present tense as well. After drew and gnew were borrowed from the north, though, this situation no longer obtained. Most verbs had /Ou/, but some had /au/. This situation seems to have led to what can be described as a generalizing of the environment in which the rule applied, or a creation of a product-oriented schema, in which the vowel of the present was irrelevant. Other verbs that joined this class in the 14th century exhibited a variety of present tense vowels, which have survived to the present day. An uncontroversial example is slay, which in the 14th century began to replace its inherited preterite slōg with slew. Welna (1996: 137-8) attributes the replacement to analogy with knew, threw, grew, etc. The fact that slay possesses all the necessary attributes for joining this class—the initial consonant cluster and the 83 absence of a coda—means that the mechanism by which the analogy proceeded is well-defined. The same applies to flay, which in the 14th century acquired a preterite flew, although that form eventually lost out to the weak preterite. More controversial is why fly has the preterite flew. The explanation the OED proffers is “confusion with flow (OE pa. tense fléow), with which this vb. had in the 15th c. come to coincide in the pa. pple; cf. however the somewhat similar phenomenon in the verb slay, pa. tense slew, for which no parallel explanation can be given.” However, according to the OED itself,the past tense flew of flow did not survive so long. “The wk. pa. tense and pa. pple appear in early ME.; the original str. pa. tense appears not to have survived into the 14th century” (OED s.v. flow). Nor does the MED provide any examples of flew as a preterite of flow after the 13th century. It is therefore difficult to see how an analogy between fly and flow could have proceeded in the 15th century, and I cannot accept this explanation. Other scholars, such as Long (1944: 46), following Luick (1921: §§419, 427), explain flew via dissimilation, whereby flōw became flūw and was from there dissimilated to fliu <flew>. While there is no direct evidence against this account, there is no apparent motivation for it either. The explanation given by Horn (1911: 36) and Price (1910: §46) is analogy with the Class VII verbs knew, threw, grew, etc. Given that fly has an initial consonant cluster and lacks a coda, flew fits the criteria for membership in the class of <-ew> verbs. Furthermore, by the 15th century, the type frequency of this class had been increased by the addition of snow, draw, gnaw, and slay, so we can see that it was both a sizable and a productive class when fly entered it. I therefore see no reason to explain fly ∼ flew any differently than flay ∼ flew, likewise first attested in the 15th century, was explained above. Both can be explained the same way as snow, draw, gnaw, 84 and slay a century earlier, and thanks to the number of its predecessors leading to a high type frequency for this class, flew is even less surprising as an analogical preterite than they were. The fact that fly ∼ flew survived into PDE and flay became weak is accounted for by token frequency. The LAEME corpus contains 120 instances of the lexeme fly and only 12 of flay. The fact that fly ∼ flew won out over the competing strong preterites fleih/fleiZ and flow, I attribute to the high type frequency of the <-ew> preterite. These are all the relevant instances of the spread of the <-ew> preterite I have been able to find: snow, draw, gnaw, claw, slay, flay, and fly. Instances of the spread in verbs that lack an initial cluster, such as saw and daw ’dawn’, are limited to Scots English, where they spread to the north of England, but not the south. Scots constitutes a separate dialect, in which the cluster was apparently not a sine qua non for entrance into the class of <-ew> verbs. A separate study involving frequencies and dates of attestation in Scots would be called for to explain the behavior of this class in this dialect. One might investigate whether the Class VII members that lacked a cluster, such as mow, sow, row, low, lost their strong preterites later than in England. Perhaps these verbs were more frequent in Scotland, which prevented the <-ew> preterite from losing its association with cluster-less verbs, as happened elsewhere. In any case, the different linguistic situation that obtained in Scots does not impact on the East Midlands dialect that most influenced standard Present Day British and American English. Even more anomalous is laugh, which fails utterly to fit the schema for <-ew> preterites, as it both lacks an initial consonant cluster and possesses a coda, yet the MED lists leu3(e, leuh, leu as preterites. According to the MED, “Past forms in -eu-, -ei- may be due in part to anal. with the forms of verbs like knouen, 85 sēn, etc.” While leu itself at least partly fits the schema in lacking a coda, it is a secondary form that can be derived from the others through loss of [Z]. The forms with a coda are primary. Because they fail to fit the schema, we should seek outside Class VII for an explanation of the <-eu> preterites of laugh. There are other unexpected preterites listed in the MED, such as leigh and leie, and the behavior of laugh is peculiar enough to warrant further study of its own. In Albright and Hayes (2003), the authors present the results of an experiment testing native speakers’ judgments of the acceptability of various preterites for nonce words. One verb form of interest was the form frew, which some speakers accepted as a possible past tense for fro (40). Unfortunately, no verbs without clusters, such as fo, are included for comparison, as the authors were testing a different hypothesis altogether. Based on the instances of verbs that acquired an <-ew> preterite in the 14th and 15th centuries, I conclude that the presence of an initial cluster is an important feature in describing this class. The following section relates these instances of the spread of <-ew> preterites to new members, to the patterns of survival of the <-ew> preterites in original OE Class VII verbs. 3.3.3 Word Structure and the Survival of <-ew> Preterites The principles behind the survival of infrequent verbs belonging to a given ablaut pattern overlap with the principles behind the spread of that ablaut pattern. For highly frequent verbs, an irregular preterite is easy to recall, because of the many exemplars stored in the memory. For verbs of lower frequency, recall is more difficult. This is where type frequency and phonological similarity come into play. To take an example from the sing-cling verbs discussed in the first half of this 86 chapter, it is not reasonable to suppose that clung survived in accordance with the frequency hypothesis. In all corpora I have examined in all periods, its token frequency is low. It is more reasonable to suppose that clung survived because when exemplars of its preterite were too few to be accessed in a speaker’s memory, the speaker was able to generate a preterite based on the large and robust class to which cling belonged. In much the same way, when no exemplars of the preterite of string could be accessed when it was first created as a denominal verb, because no preterite had yet been uttered in the history of English, the preterite strung was generated based on its phonological similarity to an existing class with high type frequency. In the case of <-ew> preterites, I argue that neither token frequency nor word structure alone can explain the patterns of survival, but that they interacted and reinforced each other. I repeat here the list of verbs whose survival is to be explained: blow, crow, flow, glow, grow, know, low, mow, row, sow, and throw. Table 3.13 in section 3.3.1 showed that the token frequencies of these verbs in PDE correlated well with their morphological outcomes, whereas their token frequencies in OE and ME correlated badly. Because it was in ME that the competition between weak and strong forms led to the loss of strong forms, with strong forms of eventual weak verbs such as mow tending to be last attested in the 14th and 15th centuries, we must still explain the outcomes of verbs with reference to the token frequencies of ME. While it might be the case that the 20th century outcomes can be explained through token frequency changes over time, the fifteenth century outcomes were much the same as they are today, but the frequencies were very different. There are two options. One may assume that for these particular strong verbs–but not for most of the others–the ME corpora do an 87 especially poor job of reflecting the actual frequencies in the spoken language, and we should assume that the PDE frequency distribution held in ME as well. Or one may look to the state of the language preserved in ME records for an explanation based on both frequency and word structure. For low frequency verbs, the principles behind survival overlap with these principles of productivity. In the case of crow, the token frequency was never high at any stage in the language. I therefore treat its case as comparable to clung. When the strong preterite crew could otherwise have been expected to disappear from lack of sufficiently exemplars, phonological similarity to a class of similar verbs saved it. Crew survives today, especially in British English (Welna 1996: 194) and in usage with animals as opposed to humans (OED), contrary to the predictions of the frequency hypothesis. In contrast, the verb low, row and mow, which have always been of relatively low frequency, lost their strong preterites and never recovered them through the means of phonological similarity. Similarly, when the originally high frequency verb sow declined in frequency between EME and PDE, it failed to keep its strong preterite, because of its lack of cluster. When verbs of originally low frequency increased in frequency, they created the illusion in PDE that token frequencies are sufficient to explain inflectional outcome, such that throw and grow are in PDE strong verbs of high frequency. However, it is necessary to explain why the strong preterites threw and grew survived until their frequency picked up. Such was not the case for all verbs that increased in frequency, such as walk. Walk never had a robust inflectional class to fit into, so it became weak, even though its token frequency in PDE is very high. In the case of throw and grow, they had the consonant cluster that, like crow, permitted their strong preterites to overcome the effects of low frequency. Blow is easy to explain, 88 with both an initial consonant cluster and relatively high token frequency. Know possessed a consonant cluster, as its spelling indicates, until EMnE. Its token frequency is sufficiently high that we should expect it to remain strong despite its subsequent loss of the cluster. The contingency table in 3.14 shows the correlation between preterite and cluster for the 12 inherited strong verbs under consideration. Table 3.14: Cluster ∼ Outcome Correlation Cluster No Cluster Strong know, grow, throw, blow, crow Weak glow, flow sow, hew, mow, low, row Such an arrangement requires the use of the ME data, for in OE low, hlōwan, had a cluster, and beginning in EME, know had no cluster. The fact that it is precisely the ME data that exhibit the best fit for presence and absence of clusters is encouraging for this hypothesis. It is precisely in ME that the cluster was demonstrably important for productivity, and it is in ME that strong verbs without the cluster began to become predominantly weak. I thus argue that the presence or absence of a consonant cluster, in company with token frequency, governed the survival of strong inflection in the <-ew> verbs, just as it governed the attraction of new verbs into the class. Two exceptions remain: flow and glow, which became weak despite the presence of a cluster, and in the case of flow, despite relatively high token frequency. The following section offers an idiosyncratic explanation for each of these verbs. 89 3.3.4 Exceptions to the Word Structure Hypothesis Flow In order to understand why flew did not survive as the preterite of flow, the form should be considered in the context of four similar-sounding strong verbs, fly, flee, flay and flow. All four were strong verbs in OE, and conjugated with the pattern shown in table 3.15. Fly and flee were so similar that the MED categorizes forms as belonging to one or the other headword according to semantics rather than according to form, and even then the distinctions may be fuzzy. Table 3.15: Fly, flee, flow, flay Infinitive ‘flow’ flōwan ‘fly’ flēogan ‘flee’ flēon ‘flay’ flēan Pret. Sg flēow flēah flēah flōg Pret. Pl. flēowon flugon flugon flōgon Past. Part. flōwen flogen flogen flagen At one time or another, all exhibited the preterite flew. Flow, originally a Class VII verb, inherited flew. According to the OED, it disappeared by the 13th century. Flay, it was seen in section 3.3.2, acquired the preterite flew in the 14th century. Fly, as has also been stated, acquired flew in the 15th century. At the same time as, and probably not independently from, fly, flee also acquired flew. The confusion of forms and meanings is so great that I hesitate to claim flee as a separate instance of a verb acquiring flew. This rather confusing state of affairs is presented graphically in Table 3.16. In PDE, fly and flee have largely differentiated their semantics, and the preterite of the former is flew and of the latter is fled. The fact that a weak preterite won out over all of the several strong preterites of flee, is attributed by the MED (s.v. 90 Table 3.16: Attestations of flew 13th cent. ‘flow’ X ‘flay’ ‘flee’ ‘fly’ 14th cent. 15th cent. X X X X flēn) attributes to the desire to differentiate flee and fly. In other words, avoidance of homophony is at work here. I submit that if, in the 13th centuries and following, flee was being differentiated from fly through the introduction of a weak preterite, the same thing might have been happening to flow. It was in the 13th century that the past participles came to coincide, the <og> of flogen ‘flown (fly)’ and the /o:w/ of flowen ’flowed’ merging in /Ou/ (Lass 1992: 50-52). Additionally, we have seen that flee, hand-in-hand with fly and flay, acquired a strong preterite flew by analogy with the verbs of Class VII, which includes flow. The evidence suggests that all four verbs were intertwined, with flee and fly the most similar, flow somewhat less so, and flay still more distant. Given all the confusion among four verbs, and the fact that fly and flee fell together in various dialects of English and other Germanic languages, the triumph of both weak preterites fled and flowed may be explained by avoidance of homophony. Glow Glow has always been a low frequency verb, so it is not altogether surprising that it should be weak in PDE. However, the same holds true for crow, which has retained its strong preterite to a surprising degree, though it is on the decline, and it is a safe prediction that crew will be the next preterite of this class to disap- 91 pear. The hypothesis that the word structure, in the form of a consonant cluster, played a role in preserving strong inflection does not account for the loss of glew. The OED, independently of any hypothesis about consonant clusters, proposes that the word may not be descended from OE glōwan, but from a Scandinavian borrowing. Their reasoning is that the word is weak in all Germanic languages except English, and in English after OE. If the word were descended from the OE strong verb, a strong outcome would be expected. A sizable number of verbs, including give and get, were borrowed from Scandinavian and came to replace the existing inherited cognate, and glow might be one of these. The OED’s claim that glow is “weak after OE” is not entirely accurate, as attestations of glew exist in the 15th century, though weak preterites are attested earlier, in the 14th century. Such late attestations, however, can be explained in the same way as the unoriginal preterites snew, drew, etc. In the cases of verbs with consonant clusters that inherited <-ew> preterites, strong preterites are attested at least as early as weak preterites in ME. In the case of glow, its ME attestations resemble a verb that began as a weak verb and later acquired strong <-ew> preterites by analogy, like claw. The explanation is admittedly ad hoc, but it was proposed by the editors of the OED presumably without any thought of the consonant cluster hypothesis, it is consonant with the Germanic data, and it explains a weak outcome even more surprising in light of the consonant cluster in glow. 3.3.5 Motivations Having claimed that an initial consonant cluster helps many strong verbs to survive, I now offer and evaluate possible explanations for why the cluster should be 92 of such importance. It is especially surprising that the onset should be so prominent, as it is usually the coda that is salient in such cases. The unexpectedness of the role of the onset is discussed in Bybee and Moder (1983: 141). In their case, they had found the cluster to be one of the features, though not a sine qua non, that correlates with membership in the sing-cling verb class. For supporting evidence, they pointed to a study by Zubin and Koepcke (1981) on German nouns, which found a correlation between masculine gender and the presence of a consonant cluster. To these examples, I add the case of English verbs with <-ew> preterites. I divide possible psycholinguistic motivations for preferring strong preterites with an initial consonant cluster into two categories, distributional and functional. I define a distributional account as one where the correlation between a feature and a category developed as an accident of the language, from the particular combination of the frequencies of phonemes, sequences, and words in the language. Cue validity is an example of a distributional account. If we argue that preterites in -ung are favored because few English nouns and adjectives end in -ung, we are making a prediction that in a different English, one in which that nouns ending in -ung abounded while those ending in -ang were rare, preterites in -ang would be preferred. In contrast, I define a functional account as one that proposes that a feature has some inherent property that affects its behavior. For example, an argument that long vowels are preferred to short vowels in some contexts because their greater duration allows them to be better heard by the listener is a functional account. It is an inherent property of long vowels that they are longer than short vowels, independent of the structure of the language. In the following two 93 subsections, I present and evaluate both functional and distributional accounts for the importance of the initial consonant cluster in <-ew> verbs. Functional Here I present two possible functional explanations for the relevance of the initial consonant cluster that have been proposed. The evidence weighs against the first, but the second possibility remains, according to current knowledge, open. Bybee and Slobin (1982) conducted an experiment in which they found that the less a verb’s preterite resembled its present, the more difficult it was for children to produce the preterite when given the present. Children had the greatest difficulty with suppletive and very irregular preterites such as went and made, and more difficulty with words that lack codas, such as blow, know, and see, than with words that have codas, such as break, sing, and bite. Bybee and Slobin concluded that the more consonantal structure a verb has, the more irregularity it tolerates, because “a greater phonological distance makes the accessing task more difficult” (113). If this should be the case, then it would be reasonable to extrapolate that speakers can be sensitive to even finer distinctions, such as that between the single shared consonant of sow and sew, and the two shared consonants of grow and grew. However, doubt is cast on such a hypothesis by Rumelhart and McClelland (1987). They constructed a connectionist model which simulated the learning of English past tenses, and their learner similarly had the greatest difficulty with suppletive and very irregular preterites. However, because their model was always given the present and preterite together, the difficulty was not with connecting the two. As a result, they interpreted these results differently. They conclude that it is not that the degree of difference between preterite and present regulates 94 the difficulty of the accessing task, but that irregular preterites have low type frequency. This low type frequency is what makes them more difficult to learn. Subsequently, Bybee and Newman (1995) addressed the question of whether stem changes are inherently more difficult to master than affixation processes. In a connectionist model, both are handled by the same mechanism. Bybee and Newman, therefore, investigated why stem changes often do turn out to be more difficult to learn than affixes, and as a result of their experiments, they concluded that it is the lower type frequency of the stem changes that are to blame. Therefore, the evidence is weak that mow, sow, low, and row became weak because the lack of an initial consonant cluster made it more difficult for speakers to access the preterite, given the present. If the strength of the phonological connection between the preterite and present, however, is of dubious relevance, the connection between preterite and preterite may still be important. In a connectionist framework, using product-oriented schemas, preterites such as drew and slew are generated because of their similarity to existing preterites. The stronger the phonological similarities, the more likely the new preterite is to be generated. It is an inherent property of consonant clusters that they create the possibility of longer identical sequences. A verb with the shape C1 ew can have consonants in common only with homophones of itself. A verb C1 C2 ew, however, can have the sequence C2 ew in common with many verbs. Thus drew shared the sequence /reu/ with several verbs, such as threw, grew, and crew. It is thus more phonologically reinforced than a verb with a more limited structure, such as bow, could ever be. In a rule-based framework such as that of Albright and Hayes (2003), the advantage of the cluster could be encapsulated by positing that speakers arrive at two rules, one general rule that generates <-ew> 95 preterites, and another rule that generates them in a context following /r/. Two rules are better than one. The consonant cluster provides an inherent potential functional advantage, the possibility of more similar verbs, which is realized by the distributional facts of the language, namely the existence of such verbs. Distributional Parallel to the argument that cue validity played a role in the favoring of -ung preterites over ang preterites, this section argues that cue validity played a role in favoring <-ew> preterites with a cluster over those without. The evidence supports the hypothesis that in ME, the distributional facts of English were such that the structure CCew correlated well with preterites, while the structure Cew did not. I obtained the distributional facts by searching the MED for word-final instances of the orthographic sequences <eu>, <eue>, <eugh>, <eu3>, <euh>, <eouh>, <eoue>, <iu>, <iue>, <ew>, <ewe>, <eowe>, <eowæ>, <eou>, these being the spellings that the MED lists for the preterite of knouen ‘know’. I used know because its token frequency is the highest of the verbs with <ew> preterites, and therefore it includes the greatest variety of spellings in its preterites. I reduced the list to the words that were pronounced with /eu/ rather than /iu/ or /Eu/. Table 3.17 presents the number of lexemes in the MED that had a form in CCew or Cew, according to whether they were strong preterites or not. Table 3.18 presents the number of hits of CCew and Cew forms when searches were carried out in LAEME on the words represented in Table 3.17. The percentages in the third row reflect a measure of cue validity. In this case, the cue is the word structure CCew or Cew, and the category is the set of strong preterites. CCew was a better predictor of the category preterite than Cew, 96 Table 3.17: MED CCew Types vs. Cew Types CCew Strong Preterite 141 Other 123 % Strong Preterite 54% Cew 62 184 25% Table 3.18: LAEME CCew Tokens vs. Cew Tokens Preterite Other % Preterite CCew 62 170 27% Cew 15 192 7% because if an EME speaker heard a form with the structure CCew, there was a 27% chance that it was a strong preterite, whereas there was only a 7% chance that the Cew corresponded to a strong preterite. A z-test shows that the difference is statistically significant, with a confidence level approaching 100%. The numbers of types in Table 3.17 are too small to support high confidence levels, but I include the figures, because some of these types represent forms that do not appear in English until after the period covered by LAEME, or do not appear due to low token frequency. The data may be of interest to other scholars. 3.4 Conclusions Two sets of English strong verbs have been presented, which behave in similar ways. In both sets, token frequency alone is inadequate to predict fully which verbs retained their strong inflection and which have become weak. Though the PDE frequencies for the <-ew> verbs give the illusion of near perfect prediction, 97 they conceal several changes in relative frequency. Frequencies at earlier stages of the language fail to explain the behavior of the verbs at earlier stages of the language. For an account with more predictive power, the structure of the words must be taken into account. In some cases of very high or low frequency, such as know and low, outcome correlates perfectly with token frequency at all stages of the language. In other cases, the word structure reinforced the preterite of a low-frequency verb. Of these, some, such as grow, increased their frequency over time, whereas others, such as crow, did not. In both sets of strong verbs, the presence of an initial consonant cluster was found to be relevant, in support of increasing evidence that the rime is not the only part of the word relevant for inflectional morphology. Bybee and Moder (1983) studied the sing-cling verbs, and they concluded that English exhibits a sort of “whole-word morphology”, gestalt-like, in which morphological information is not concentrated at the end of the word, but spread out over the entire word. My research on the <-ew> verbs supports this view of English morphology. The favored structure for preterites was expressed in terms of the entire word, CCew, which encapsulates the initial consonant cluster, the nucleus, and the lack of coda. It may be the case that the onset became all the more important because of the lack of any coda. These are the aspects of the methodology that I wish to place particular emphasis on, for they fill gaps in the previous literature. First, the importance of looking for any possible frequency changes over time, a practice that has been carried out neither by theoretical linguists nor by scholars of the history of English. Second, the importance of taking into account both frequency and phonological similarity, something that has been carried out better by in the field of linguistics 98 than in the history of English. Third, the similarity of the operative principles governing survival and productivity of strong inflection. The effects of word structure on productivity of irregular inflection and its interaction with frequency have been well studied by Bybee, but less thoroughly for its effects on survival. 99 Chapter 4 Vowel Quantity 4.1 Introduction This chapter addresses the role of vowel quantity in the history of strong verbs: in determining the PDE status of a verb as strong or weak; in generating a slew of competing strong preterites for many Middle English (ME) verbs; and in making the eventual selection of one of those strong preterites for most verbs that remain strong in the standard dialect. The first section presents a history of phonological changes to the quantity of vowels and illustrates how these changes affected verbal inflection. There follows a description of various forms that arose through morphological changes, and of the resulting state of affairs, where most verbs exhibited a variety of vocalisms in their preterites and past participles. I explain the dialectal origin of some of these changes, and how they spread beyond their original borders. In section 4.5, I argue that the rise of some of these forms, and the eventual reduction of the free variation to only one possible preterite, makes sense if long vowels were preferred 100 in strong verb preterites. In some cases, the preference for long vowels arose primarily for distributional reasons, when forms were under pressure to be more like other strong verb forms. In other cases, long vowels were preferred primarily because of their greater perceptual salience. The motivations for the effects of vowel quantity are treated in section 4.6. Under consideration are the verbs that conform to the general patterns of classes I-V. I adduce evidence from Class VI verbs to help explain the behavior of classes I-V, but the behavior of Class VI verbs themselves is treated in Chapter 2. For similar reasons, I disregard very high frequency verbs such as see, sit, lie, and come, which, although they were members of these classes, exhibited various phonological and morphological anomalies, and which probably neither influenced nor were influenced by the rest of the verbs in their classes. 4.2 Phonological Changes In ME, a series of phonological changes, listed below, applied to the vowels, causing much disruption to the ablaut patterns of the strong verbs. These changes are listed below in chronological order and then described. • Homorganic Cluster Lengthening • Pre-Cluster Shortening • Monophthongization of OE diphthongs • /a:/ > /O:/ • Middle English Open Syllable Lengthening 101 The simplest of these changes is the unconditioned shift of /a:/ to /O:/. Monophthongization of Old English (OE) diphthongs took place in the south18 in the 11th century, turning <ēo> /ea/ into /e:/, <ēa> /æa/ into /E:/ and <ea> /ĕo/ into /E/. Vowels were lengthened, and lowered slightly, in an environment traditionally described as an open syllable, a change the textbooks style Middle English Open Syllable Lengthening (MEOSL). Minkova (1982) argues that a restriction of the environment is necessary, but for the nonce, “open syllable” makes an adequate first approximation of the environment, though it will be necessary to refine the rule later. Similar is Homorganic Cluster Lengthening (HCL). Because this is primarily a morphological work, the phonological imprecision of the name HCL and its traditional description need not be treated in detail. It is sufficient to list the changes that affected the strong verbs. For further discussion of the rule from a phonological perspective, see Stockwell and Minkova (1992). All vowels were subject to lengthening before /–ld/, though not without sporadic exceptions19 . High vowels lengthened before /nd/. Lengthening of at least some vowels, as evidenced by spellings such as <soong>, took place before /ng/, but then shortened again. Low vowels did not undergo lengthening. It is unclear exactly what happened before <mb>, although it is certain that the infinitive of climb underwent lengthening. Before other clusters, short vowels remained short, and long vowels shortened. 4.2.1 Class I Class I verbs had /O:/ in the preterite singular after the application of [4], and a long vowel in the infinitive and by implication, in the present, after the application 102 of MEOSL [5]. Because MEOSL failed to apply consistently to high vowels, the past participles of ME exhibited variation. Even as late as Caxton are found the lengthened variants with /e:/, such as wrēten, alongside unlengthened variants such as written (Lass 1992: 131). Table 4.1 shows the vocalisms of OE and the new vocalisms of ME, including the uncertainty of quantity in the ME preterite plural and past participle. Table 4.1: Class I drive infinitive preterite singular OE dri:van dra:f ME dri:v@n drO:f 4.2.2 preterite plural drivon driv@n (dre:v@n) past participle driven driv@n(dre:v@n) Class II Class II verbs, after the monophthongization of OE diphthongs [3], had [e:] in the infinitive and present, and [E:] in the preterite singular. MEOSL [5] applied in the past participle, leading to /O:/. Lengthening from MEOSL is expected in the preterite plural, although it ends up mostly obscured due to a tendency to level the vowel of either the past participle or the preterite singular into the preterite plural. The Middle English Dictionary (MED) records some early forms such as <curen> and <cusen>, but <chōsen>, with /O:/ from the participle, predominates. The hypothetically lengthened and lowered version is therefore asterisked. Table 4.2 compares the ablaut patterns of OE and ME. Note also the consonantal leveling of Verner’s Law, extending the /z/ throughout the paradigm. The original /r/ remains in isolated forms such as lovelorn. 103 Table 4.2: Class II freeze infinitive preterite singular OE freozan fræas ME fre:z@n frE:s 4.2.3 preterite plural fruron *frO:z@n past participle froren frO:z@n Class III Class III verbs ultimately splintered as a result of Homorganic Cluster Lengthening. At first, the infinitive, preterite plural, and past participle of verbs ending in /nd/ and /ŋg/ lengthened. The long vowels before /ŋg/ then shortened. Ultimately, due to this shortening, the two stem types ended up with different patterns. The preterite singular vowel /a/ did not lengthen, being a low vowel and therefore not subject to HCL. An allophone of /a/ before nasals did exist, dating back to Mercian in OE, and continuing in the West Midlands dialect of ME (Wright 1925: 42). This allophone was [O]. There is evidence from spellings such as <foond> and <soong> that this /O/ allophone was subject to HCL, but /O/ before a nasal eventually lost out to its competitor /a/, such that the variants man and land were selected over the variants mon and lond. The one environment in which /O/ persisted was before /ŋg/, such that the variants long and strong were selected over lang and strang. However, in the preterite singular of class III verbs, the /a/ variant won out even before /ŋg/, such that the variant sprang was selected over the variant sprong20 . Tables 4.3 and 4.4 show the development of ablaut in Class III verbs subject to HCL. Wright (1923: 38-39) asserts that the lengthening was undone by the middle of the fourteenth century. The use of digraphs in later 104 authors, such as Chaucer21 , may therefore reflect conservative orthography, or a sporadic lengthening in this environment. Table 4.3: Class IIIa sing OE ME pre-1350 ME post-1350 infinitive siŋgan si:ŋgen sI:ŋgen preterite singular saŋg saŋg, sO:ŋg saŋg preterite plural suŋgon su:ŋgen suŋgen past participle suŋgen su:ŋgen suŋgen Table 4.4: Class IIIb bind OE ME infinitive preterite singular bindan band bi:nden band, bO:nd preterite plural bundon bu:nden past participle bunden bu:nden In the set of Class III strong verbs where the final cluster was not homorganic, HCL never applied. Furthermore, had there ever been any long vowels there, they would have been shortened through the application of [2], pre-cluster shortening. Table 4.5 shows the essential continuity of the ablaut pattern. Table 4.5: Class IIIc help OE ME 4.2.4 infinitive preterite singular helpan hælp help@n halp preterite plural hulpon hulp@n past participle holpen holp@n Classes IV and V As noted in the introduction, Classes IV and V in OE differed only in the past participle, where Class IV had /o/ and Class V had /e/. Elsewhere they were identical. This overlap in paradigms led to some interchange between the classes, where verbs that properly belonged to Class IV exhibit some occurrences of /e/ 105 in their participles, and vice versa. The ME phonological change that affected the verbs of these classes is MEOSL, which lengthened the vowels of the infinitive and past participle, but not of the preterite singular. The preterite plural had /æ:/ in OE, which was raised in ME to /E:/, but its quantity was left untouched by ME lengthenings and shortenings. Tables 4.6 and 4.7 show the OE and ME ablaut. Table 4.6: Class IV break infinitive preterite singular OE brekan bræk ME brE:k@n brak preterite plural bræ:kon brE:k@n past participle broken brO:k@n Table 4.7: Class V weave OE ME 4.2.5 infinitive preterite singular wevan wæf wE:v@n waf preterite plural wæ:von wE:v@n past participle weven wE:v@n ClassVI MEOSL also lengthened the vowels of the infinitive and past participle in Class VI. The preterite was already long in the singular and plural, and it remained so. Table 4.8 shows the OE and ME ablaut. Table 4.8: Class V (for)sake infinitive preterite singular OE sakan so:k ME sa:k@n so:k preterite plural so:kon so:k@n past participle saken sa:k@n Such are the expected outcomes of the ME strong verb classes I-VI after the application of sound changes. These phonologically regular patterns, though, were 106 subject to extensive morphological change. In addition to acquiring weak forms, these verbs acquired multiple vocalisms in the strong preterites and past participles. By the end of ME, most verbs exhibited a bewildering array of forms, detailed in the following section. 4.3 Analogical Changes Analogical changes to the ablaut patterns in the strong verbs were present already in OE. ME saw an upswing in the number of possible variants for a given element in the paradigm. This is no doubt partly because of an increase in the size of the attested corpus, which allowed the written record to capture more of the variety of the spoken language, including variants particular to different dialects. It is also partly because further analogies applied during ME, leaving fifteenth-century speakers with more options for the preterites of many verbs than twelfth-speakers had. The current section of this chapter details the new variants that arose for analogical reasons and were added to the phonologically regular forms. For Early Middle English (EME), the data are taken from the Linguistic Atlas of Early Middle English (LAEME), and for the end of ME, the results of Long (1944) are used. Long (1944) is a reference work containing all of the strong verb forms found by the author in a fifteenth-century corpus. The disadvantage of its methodology is that token frequencies are not given, only the number of texts in which a form occurs. However, since the present work is interested primarily in which analogies took place, and only secondarily in the relative frequency of variants, the usefulness of Long (1944) was deemed sufficient to outweigh the time and effort required to replicate the research. 107 4.3.1 General Remarks In ME, there was a general tendency for the 2nd person preterite singular to be leveled under the vowel of the 1st and 3rd preterite singular, so that there was a single form of the stem for the preterite singular.22 The vocalism of the 1st and 3rd preterite singular won out over the vocalism of the 2nd singular. Presumably the greater token frequency of these slots in the paradigm, as seen in Table 4.9, played a role. Table 4.9: 2nd sg. vs. 1st and 3rd sg. Class Class Class Class Class Class Class Total I: rise II: flee III: (be)gin IV: come V: see VI: stand VII: let 1st & 3rd singular preterite 99 33 269 1027 418 259 163 2268 2nd singular preterite 1 0 1 26 36 8 8 80 However, the nature of the written records means that the frequency of the 2nd singular in the spoken language is underrepresented in the corpus. In spite of the inadequacy of the written records, we may point to a general linguistic tendency for the 3rd singular to serve as the basis for analogy. Watkins (1969: 90) writes, “It is the 3 sg. which will tend to impose its form on the rest of the paradigm, irrespective of the form of the 2 sg. or any other person, owing to the peculiar functional position of the 3 sg. as ’la personne zéro’, ’la non-personne’, as Benveniste has put it.” See further in Watkins (91ff) for an account of the nature of the 3 sg. Subsequent to the leveling of the preterite singular, the tendency was for the 108 preterite singular and plural to be leveled under a single form, which led to the reduction of the strong verb system from four principal parts in OE to three in Present Day English (PDE). Because the preterite plural was less frequent than the preterite singular, the resulting uniform preterite usually had the vowel of the preterite singular rather than that of the preterite plural. Cases where the preterite singular appears to have acquired the vowel of the preterite plural are rare and require special explanation. 4.3.2 Class I Of the classes under consideration in this chapter, Class I was the most stable. For the most part, the preterite singular and the past participle were conservative. In keeping with the general tendency to level the preterite singular and plural into a single preterite form, the preterite plural acquired the vowel of the preterite singular. Thus, PDE has “he rose” and “they rose” instead of the phonologically regular outcome “he rose” and “they ris”. The fifteenth century data in Long (1944) show the existence of some limited analogies that are not found in LAEME. In rare cases, the vowel of the preterite has been extended to the past participle, as in droven, and vice versa, as in smit. Table 4.10 shows the occurrences of analogical extensions vs. forms with conservative ablaut in LAEME and Long. The numbers in the columns for LAEME represent token frequency counts for the verbs bide, drive, glide, gripe, ride, rise, shine, slide, stride, write, and writhe. Unfortunately, as noted above, the numbers from Long do not represent token frequencies, but the number of texts in which a form occurs. If a single text contains both inherited and analogically extended forms for a single principal part, that text is counted twice. This is not an ideal method 109 of representing the data, but it follows from the methodology of Long23 . Table 4.10: Class I analogy Conservative vowel LAEME Pret. Sg. 249 100% Pret. Pl. 49 88% Past Part. 200 100% Conservative vowel Long (1944) 188 90% 49 40% 213 98% Analogically extended vowel LAEME 0 0% 7 12% 0 0% Analogically extended vowel Long (1944) 211 10% 75 60% 4 2% From the numbers in Table 10, we can characterize the data in the following manner: analogical extensions are more common at the end of ME than in Early Middle English (EME), but they remain exceptional outside the leveling of the preterite plural under the vowel of the preterite singular. In all cases where the /i/ of the past participle has been extended to the preterite singular1, the root ends in a dental. Thus writ is a possible preterite, but driv is not. The variation in Class I verbs by the end of ME is shown in Table 4.11, using write as the exemplum. Table 4.11: Class I Variation Pret. Sg. write wrO:t, writ 4.3.3 Pret. Pl. writ@n, wrO:t@n Past Part. writ@n, wrE:t@n, wrO:t@n Class II Class II was rather less conservative than Class I. In addition to the leveling of the preterite plural under the vowel of the preterite singular, several other analogical extensions were made during the course of ME. Spreading of vowels from the 110 preterite to the past participle and vice versa were found, as well as spreading of vowels from Class IV and V verbs. The former is an intra-paradigmatic analogy and the latter inter-paradigmatic. Table 12 illustrates the distribution of conservative and analogically spread vowels in the LAEME corpus and the fifteenth century corpus of Long (1944). The verbs used for the LAEME searches are bid (bēodan), brook, choose, cleave (clēofan), creep, freeze, reek, shoot, shove, and seethe. Verbs with stems ending originally in /w/ and /g/ are excluded because of the diphthongizations that took place in EME. When the shape of the root was changed, the verbs no longer resembled the other Class II verbs and no longer behaved as members of the class. Table 4.12: Class II analogy Conservative LAEME Pret. Sg. 67 Pret. Pl. 13 Past Part. 130 Intra Long LAEME 40 4 0 13 151 3 Inter Long LAEME 27 4 42 0 5 0 Long 27 2 0 Class II displays the same trend as Class I, an increase in analogical extension. The increase is not only in the percentage of forms that are the result of analogies, for which Long’s data are not numerically reliable, but also in the variety of analogical changes. In Long’s corpus, there were no instances of the inherited preterite plural; rather, there were three analogically produced forms: the /e:/ of the preterite singular, the /O:/ of the past participle, and the /a:/ borrowed from the preterite plural of Class IV and V verbs (see section 3.5 below). The first two are instances of intra-paradigmatic analogy, and the third inter-paradigmatic. The inter-paradigmatic analogy is not found at all in LAEME, having not arisen or not become frequent until a later period. 111 In the LAEME corpus, there are no instances where the /O:/ has been spread to the preterite singular. Such preterites, e.g. froze and chose, are attested later in ME, alongside forms such as chese24 . In Early Modern English (EMnE), forms with /O:/ dominate. The only preterite of choose in the King James Version is chose. Only rarely was the /e:/ of the preterite singular extended to the past participle in any period. There are no instances of chesen or ceren in LAEME. In Long’s corpus (1944: 276), there are 5 texts with instances of Class II participles with /e:/, out of 193 total texts with Class II participles. In addition to the intraparadigmatic extension of the /O:/ from the Class II past participle to the preterite singular, the inter-paradigmatic /a:/ of the Class IV and V preterite singular (see section 3.5 below) was also extended to the Class II preterite singular. In the preterite singular, the short counterparts of all three vowels, /a/, /e/, and /O/, are found. These arose phonologically, through a sporadic shortening of vowels in monosyllabic words ending in a single consonant. This proliferation of analogical extensions led to the variation of forms given in Table 4.13. The exemplum given is freeze, which was the most morphologically and phonologically conservative member of Class II, though its token frequency is so low that most forms listed are hypothetical, not necessarily representing real attestations. Forms not found in Long, LAEME, or the MED are asterisked. Of the distribution of forms, both phonologically regular and morphologically extended, Long (1944: 39) writes, “As the preterite singular forms with the stem vowels a, e, o, both long and short are widely spread and intermingle in the same texts, no conclusions can be drawn regarding dialectal distribution from these examples.” 112 Table 4.13: Class II Variation Pret. Sg. Pret. Pl. Past Part. freeze frE:z, *fra:z, *frO:z, *frE:z@n, *fra:z@n, *frE:z@n, frO:z@n *frEz, *fraz, *frOz *frO:z@n 4.3.4 Class III /nd/ verbs In Class III verbs ending in /nd/, we can easily identify a dialectal distribution for the direction in which analogy spread through the paradigm. The tendency in the north was to extend the /a/ of the preterite singular to the preterite plural. The tendency in the south, especially the west, was to extend the /u:/ of the past participle to the preterite (Lass 1992: 132). The preterite singular, descended from OE /and/, had multiple outcomes in ME. The rounded allophone of /a/ that occurred before a nasal has been referenced in section 2.3, /O/. This produced a qualitative alternation of fand /fand/ vs. fond /fOnd/. Homorganic Cluster Lengthening of /O/ produced a quantitative alternation, for there is evidence that both /fOnd/ and /fO:nd/ occurred. The frequent spelling <oond>, referred to in 4.2.3, points to the existence of forms with a long vowel. Though the Class III preterites ending in <ond> are listed exclusively by the MED with a macron, indicating a long vowel, it is possible to argue indirectly that short vowel variants existed. Preterites of /-nd/ verbs often rhyme with nouns in -and/ond25 , such as hand/hond, band/bond and land/lond. Though the MED entries for these also are given only with macrons, they must have had short vowel variants, as the PDE outcomes are hand, band, and land, with short vowels. The editors of the MED are probably making too much of the <oond> spellings by assuming 113 that all <ond> spellings also represented long vowels. Moreover, preterites ending in /and/, which existed only with a short vowel, probably outnumbered preterites with /O(:)/ throughout England. It was not possible to get frequency counts for the preterites, but LALME shows that even in the west, instances of /a/ outumbered instances of /O/ in man/mon. We can also argue from the PDE outcome of nouns like man, hand, band, and land, where /a/ won out over /O/, presumably for reasons of frequency. To conclude, the preterite singular of Class III /-nd/ had a short vowel always in the north, where HCL did not apply in this environment, and more often than not in the south. It is this inherited short vowel that eventually loses to the long vowel of the past participle in the south, resulting in PDE find ∼ found rather than find ∼ fand. Both the northern and the western preterite are exhibited already in LAEME. Table 4.14 shows the distribution of inherited and analogical preterites for the verbs bind, find, grind, and wind in LAEME and Long (1944). Table 4.14: Class III analogy Conservative vowel LAEME Pret. Sg. 116 Pret. Pl. 114 Past Part. 172 Conservative vowel Long (1944) 64 31 240 Analogically extended vowel LAEME 28 13 0 Analogically extended vowel Long (1944) 12 13 1 At no point is the /a/ of the preterite extended into the past participle. There is one instance in Long’s corpus of a past participle <boond>, which appears to have its source in the preterite singular. It is also conceivable, though not likely, that it represents the regular /u:/, because /u/ is often orthographically 114 represented as <o> before <n>. It is interesting, as Long notes (1944: 74), that even by the fifteenth century, the preterite has not yet been leveled under a single form. One might ask whether the preterites had been leveled differently in the north and the west, and whether the conflation of the two dialects into a single corpus is what leads to the appearance that leveling had not yet taken place; yet this is not so. In fifteenth-century western texts, the spelling <oond> is frequent in the preterite singular, reflecting a phonologically regular long vowel resulting from HCL. This frequent form has not yet been fully replaced by the /u:/ from the past participle. The set of possible forms, with find as the exemplum, is presented in Table 4.15. Table 4.15: Class III variation find 4.3.5 Pret. Sg. fand26 , fOnd, fO:nd, fu:nd Pret. Pl. fand@n27 , fOnd@n, fO:nd@n, fu:nd@n Past Part. fu:nden fO:nd@n28 Other Class III Verbs Most Class III verbs ending in a liquid + consonant cluster became weak early in ME. Even the highest frequency verbs, such as help, are weak in PDE, outside of certain dialects, such as Appalachian, which is a conservative area preserving features of Early Modern British English (Dictionary of American Regional English). Because of the strong preterite’s low number of attestations, it has less opportunity to show as much variation in the vowel as in other verb classes. The /O/ of the past participle sometimes spread to the preterite, as in holp. A dialectal reflex of the inherited preterite singular sometimes appears in texts from the southwest 115 of England, resulting in help rather than halp. Class III verbs ending in nasals and nasal + velar sequences, such as swim and swing, are treated in Chapter 3. They still form the largest and most productive class of strong verbs, as defined by experimental tests and analogical extensions to other verbs. Tables for the variation in these two sets of class III verbs have been deemed of limited use and are not included. 4.3.6 Classes IV and V 4.2.4 Class IV and V verbs are treated as a unit, because the first three of their four principal parts were the same, and there was much interchange between the two in the fourth. These verbs underwent even more analogies than the Class II verbs, and the result in the fifteenth century is a bewildering array of variation. Before figures for these can be computed, the difficulties in determining what orthography represents the inherited vowel and what represents an analogical extension must be addressed. In the preterite singular, the OE vowel was /æ/, whose ME outcome was /a/. Thus forms with <æ> and <a> are both treated as having preserved the inherited vowel. However, the <e> spelling is also common in LAEME, and as noted by Fisiak (1968: 18), <e> often represents /a/, which was a front vowel. With the previous data in this chapter suggesting that the preterite singular forms in LAEME have undergone relatively few analogies, I treat forms with <e> as conservative. However, there are a handful of examples with <e> and <a> that have an <e> at the end of the word, indicating the stem vowel is long. These vowels are treated as analogical, in quantity if not necessarily in quality. Along similar lines, in the preterite plural, the expected outcome of OE /æ:/ is /E:/, which is usually spelled with <e>, but in early texts is also spelled with 116 <a> in the South-East Midlands (Fisiak 1968: 38). Later in ME, however, the preterite plural was subject to the usual leveling under a single preterite form, and /a:/ is often the vowel used for the preterite singular and plural. Thus, in EMnE, the King James Bible has “he spake” and “they spake”. Therefore in LAEME, I treat the /a:/ in the preterite plural as conservative, and in Long, I treat /a:/ as analogical. The relative distribution of analogical and inherited forms, computed using these criteria for the verbs bear, break, mete, shear, speak, steal, tear, tread, weave, and wreak, are presented in Table 4.16. Table 4.16: Classes IV and V Analogy Conservative vowel LAEME Pret. Sg. 432 Pret. Pl. 155 Past Part. 194 Conservative vowel Long (1944) 50 9 202 Analogically extended vowel LAEME 9 11 15 Analogically extended vowel Long (1944) 79 57 55 The table indicates that relatively few analogies had applied to the forms in the LAEME corpus. Only a handful of examples of /O:/ spreading to the preterite or a Class V participle are to be found, and other variations in vowel quality have been treated as orthographic. The increase of analogical forms by the fifteenth century cannot be computed precisely using the data from Long, both because of the lack of token frequencies and because our methodology treats all cases of preterite plural /a:/ as analogical when some may conceivably be orthographic. However, the existence of the increase is indisputable. The /O:/ is frequent in the preterites and participles of all verbs in Long’s corpus, including verbs where /E:/ and its frequency continued to rise after ME until it replaced all other variants. The /a:/, analogical in both the preterite singular and the preterite plural, rose 117 in frequency. Barely to be found in LAEME, at least in the preterite singular, the preterite with /a:/ in the King James Bible constitutes the only possible past tense for “speak”. The origin of the /a:/ is not clear, but it is most likely a simple lengthening of the inherited /a/ in the preterite singular, motivated by the long vowels elsewhere in the paradigm. Spreading a vowel from the preterite singular to the preterite plural is a frequent occurrence, as has been seen, and that would account for the /a:/ in the preterite plural. Forms of disputed origin with /E:/ in the preterite singular arose sometime between the end of the period covered by LAEME and the fifteenth century, which means the fourteenth century. Long attributes the /E:/ to the influence of the preterite plural, but this is unlikely due to the low frequency of preterite plurals. In no other case did the preterite plural influence the preterite singular, except where the vowel of the preterite plural was identical to that of the much more frequent past participle. Morever, even without token frequencies in her data, it seems that the original /E:/ of the past participle was on the wane already. I therefore consider it more likely that in cases where the /E:/ is found in the preterite singular of Class V verbs, it spread there from the past participle, and in cases where it is found in the preterite singular of Class IV verbs, it spread there from Class V. We have already seen that there was much interchange between classes IV and V as early as OE. Table 4.17: Classes IV and V Variation Pret. Sg.

It has long been recognized (Wyld, Long, Welna, Lass) that the tendency in the north was for the preterite singular to spread to the preterite plural. Wyld’s terminology for a preterite plural with the vowel of the preterite singular is the “northern preterite.” The northern preterite is shown in Table 4.18. Table 4.18: Northern Preterite Class Class Class Class I II IV V Infinitive ri:den bind@n brE:k@n bidd@n Pret Sg. ra:d band bræk bæd Preterite Plural ra:de band bræk bæd Past participle riden bund@n brO:k@n bEd@n In the south, the ablaut patterns were more conservative, but there existed a leveling tendency, found mostly in the west, to spread the past participle to the preterite (Wyld 1927: 268-269). Wyld’s terminology for a preterite with the vowel of the participle is the “western preterite.” The western preterite is illustrated in Table 4.19. Table 4.19: Western Preterite Infinitive Class III wring@n Class III bi:nd@n Class IV brE:k@n Pret Sg. wrung bu:nd brO:k Preterite Plural wrung bu:nd brO:k Past participle wrung@n bu:nd@n brO:k@n In the case of /brO:k/, the participial vowel spread first to the preterite plural, and then to the preterite singular, as indicated by the dates given in Welna (1996: 131). 119 By the end of ME, however, the western and the northern preterites had spread to the south and joined the other morphological and phonological changes, such that Long (1944: 139) reports that a single author may exhibit free variation from among several possible vocalisms, both in quality and in quantity. Then, during EMnE, this abundance of forms was reduced such that most verbs have only one preterite29 . This state of affairs calls for a morphological account of what factors favored the variants that won out. 4.5 Vowel Quantity I argue that vowel quantity has played a critical role in the history of the strong verbs. In the south, Open Syllable Lengthening and Homorganic Cluster Lengthening created long vowels in verb paradigms. At this point, several morphological extensions, discussed in Section 4.3, resulted in ahistorical long vowels. In all cases, if a verb preterite existed in competing variants with long and short vowels, one of the long vowels won, with the exception of a few verbs ending in dentals, for which see Chapter 5. If there was more than one long vowel, one of which was /O:/, the /O:/ was eventually selected. If there were no long vowels anywhere in the paradigm, one of two situations obtained: the verb tended to become weak, as in Class IIIc verbs such as help ∼ helped, or it belonged to the very robust pattern sing ∼ sang ∼ sung (Class IIIa). In Class I, the long vowel, /O:/, of the preterite singular arose by phonological rule, and the paradigm was subject to relatively little disruption compared to other classes. Some leveling of the participle into the preterite did occur, resulting in forms such as writ30 . Such forms with a short vowel arose only before dentals, 120 and they can be explained in terms of an analogy with weak verbs, such as feed ∼ fed, that form their past tense with a short vowel before the dental. See Chapter 5 for a fuller treatment of verbs with dental-final stems. In Class II, all principal parts had long vowels by phonological rule. In addition, the preterite acquired two long vowels morphologically: /a:/ from the preterite singular of classes IV and V, and /O:/ from the past participle. These three long vowels were all sporadically shortened, possibly as a result of being in a closed syllable in the first and third singular. The fact that the morphology resulted exclusively in long vowels, whereas short vowels arose only by phonology, reinforces my hypothesis that long vowels were associated with the morphology of the strong preterite. As noted above, if the /O:/ occurred in one of the variants, that variant won. In Class II, the result is freeze ∼ froze. In Class IIIa, all vowels were apparently originally lengthened, but later shortened again. The robust survival of Class IIIa presents the only systematic exception to my hypothesis, an exception that can be explained by the very robustness of this class. See Chapter 3. In Class IIIb, the two possibilities for the preterite of bind were 1) band, representing the original preterite singular vocalism, and 2) bound, representing the vocalism of the past participle. The version with the long vowel31 won. The variant /bO:nd/, which contained a long vowel, was too badly outnumbered by band to survive, judging by man vs. mon in LALME. See the discussion in section 3.3. In the other class III verbs, preterites such as song were not numerous enough to survive, and lost out to sang. In Class IIIc, no long vowels arose in the paradigm through any means, phonological or morphological. In the 13th and 14th century, Krygier finds a statistically 121 significant correlation between verbs ending in a liquid + consonant (LC) cluster, and verbs that acquired weak preterites. Verbs ending in LC comprise Class IIIc and fold, hold, salt, walk, well, wealtan of Class VII. I argue in this chapter that the two facts are connected: the short vowels reduced the survival odds of these verbs. In Classes IV and V, the competing preterites were bar/spak, representing the original preterite singular vocalism; ba:r/spa:k, with said vowel lengthened by analogy with the other principal parts; bE:r/spE:k, which Long explains as borrowed from the preterite plural (1944: 117); and bO:r/spO:k, from the vocalism of the Class IV past participle. That any extension from the preterite plural should take place is very surprising. It is invariably the least frequent of the principal parts in all periods from OE on, and Wyld writes, “As Bülbring points out (Abl. d. starken Zeitw., pp.116-17), the Pret. Pl. type is the least permanent of the various forms of the Strong Verbs, and never survives in Mod. Engl. unless it be the type also of the Past Participle” (1927: 269). His observation is supported by the frequency data in Appendix 2. If, therefore, Long is correct in attributing the /bE:r/ of the preterite singular to the /bE:r@n/ of the preterite plural, then the best explanation is that the long vowel was a desideratum in the preterite singular. Alternatively, the source of the Class IV /E:/ was the class V preterite, whither the vowel spread from the Class V past participle. The Class IV preterite plural may then have served to reinforce it in the Class IV preterite singular. Compare Wyld’s observation that the extension of /fu:nd/ to the Class III preterite singular may have been reinforced by the preterite plural, but was probably not the main source of the vowel. Here the true account is less certain, as Class IV /E:/ comes either from an unlikely spot within the Class IV paradigm itself, the preterite 122 plural, or, more plausibly, from the Class V participle via the Class V preterite. It is unlikely that the /E:/ comes from the Class V participle via the Class IV participle, as Long reports only 3 Class IV participles with /E:/, out of a total of 204 Class IV participles. In either case, a long vowel has been spread analogically to a form that had originally a short vowel. Classes IV and V contain the only exceptional example of a morphologically extended short vowel: brak extended from the preterite singular to the preterite plural. I dispense with it on the following grounds: it is so infrequent as not to be recorded in the MED, and Welna (1996: 131) gives it as a northern form, where extension of the preterite singular to the preterite plural was the norm. In classes IV and V, the two variants /a:/ and /O:/ outlasted the others. Shakespeare has both bare and bore. In the end, in the standard dialect, /O:/ won. I conclude that in the preceding sets of verbs, we can observe the following survival patterns: • Verbs with long vowel preterites retained their strong inflection. Exception: -ang/-ung. • The preterite variant with /O:/, where it existed, won out. Exception: certain dental-final verbs. 4.6 Linguistic Motivation In no way am I arguing that the desire to have a long vowel in the preterite was behind the origin of each of the various dialectal levelings. It may be the origin of some of them, but the northern preterite, exemplified in binden ∼ band 123 ∼ band ∼ bunden, shows a clear counterexample. I suggest that the northern preterite represents simply a leveling of the preterite under the vocalism of the most common form: the first and third preterite singular. In this case, where there are no long vowels in the paradigm, frequency unhindered drives the analogy. However, I do argue that in the case of some other dialectal levelings, vowel quantity was one of the factors. Most important, though, vowel quantity played an important role in the ultimate selection in EMnE from among competing forms, regardless of their origin. As seen in the quote above from Long (1944), competing forms often coexisted in free variation within the work of a single author. While some competition among forms still exists today, it is more restricted and does not include forms that were once very common, such as spake. A priori, two possible reasons present themselves for the importance of long vowels in the history of strong verbs. One is distributional, and the other is functional. A distributional account would claim that due to the phonological changes, long vowels numerically dominated short vowels in the paradigms of strong verbs, and the remaining preterites with short vowels were made to conform to this long vowel-strong verb pattern by acquiring long vowels or by becoming weak. A functional account would claim that long vowels were more perceptually salient than short vowels; therefore they carried grammatical information better, and therefore long vowels were robustly preferred in strong preterites. These two possibilities are examined in the next two sections. 4.6.1 Distributional Account Lengthenings occured most prominently in the participles of classes II, IIIb, IV, V, and VI and in the infinitives of classes IIIb, IV, V, and VI. Classes I, II, and 124 VI had already long vowels in the preterite singular. These changes created the distribution of long vowels seen in Table 4.20. Table 4.20: EME Distribution of Long Vowels Class I II IIIa IIIb IIIc IV V VI infinitive preterite singular L L L L L L preterite plural L/S (L) L L past participle L/S L L L L L L L L L L L L L There are two ways of conceiving of the distributional relationship between long vowels and strong verb preterites. A preterite could have faced pressure to conform to other preterites, resulting in inter-paradigmatic analogy, following the arrangement of Table 4.20. There could also have been pressure to conform with other members of an individual verb’s paradigm, resulting in intra-paradigmatic analogy. At the time when long vowels were arising morphologically in strong principal parts, the creation of some of the variants was possibly driven by the particular desire to have a long vowel in the preterite. This motivation is especially probable if brE:k was formed on the basis of the preterite plural, because it provides a reason why the preterite plural, which was otherwise in the process of dying out, acted as the source for analogy in the much more frequent preterite singular. If brE:k was formed instead on the basis of the Class V preterite, itself formed on the basis of the Class V participle, the motivation may or may not have been the preference for a long vowel. Many complex reasons underlie the ablaut flux in strong verbs. 125 In any case, other candidates for extensions motivated by the preference for a long vowel exist in ba:r and fu:nd. At the time when such forms were being created, long vowels were found in the preterite singulars of only Class I, II, and VI verbs, and possibly of Class IIIa verbs ending in /ng/. Using Krygier (1994: 255-267), I count 300 ME strong verbs, of which 171, or 57%, had long vowels in the preterite singulars. A one-sample proportion z-test confirms that long vowels outnumber short vowels with a p-value of .0078, but 57% is hardly an overwhelming majority. It appears unlikely that the long vowels dominated the short vowels in preterites to such an extent as to drive out short vowel preterites in ME and make them weak. In other words, I do not believe there is evidence that inter-paradigmatic analogy was operative in eliminating the strong preterites of Class III verbs ending in LC. In section 6.2, I provide an account relying on perceptual salience to explain why these forms with short vowels before LC clusters made poor strong preterites. Intra-paradigmatic analogy, in contrast, was able to play a role at all periods after the phonological lengthenings. With the exception of verbs ending in clusters that did not permit long vowels, all verb classes had long vowels in at least three principal parts, including the infinitive/present, which served as the base. On the one hand, the method of conveying grammatical distinctions by means of ablaut requires some differences to exist between the vowels of the present and the preterite32 . On the other hand, the principle of paradigm uniformity favors similarity between members of a paradigm. The lengthening of vowels in strong verb preterites resembles a phenomenon in Swiss German presented by Kiparsky (1982). In the Kesswil dialect of Swiss German, the difference between the singular and plural of certain nouns was originally signaled by a difference in both the backness and the height of the vowels. Paradigm leveling applied such that the 126 difference was still signaled, but now only by the backness. Table 4.21 shows the vowel alternations in the paradigm before and after the leveling took place. Table 4.21: Swiss German Leveling, Kesswil Dialect Before leveling After leveling Singular bOd@ bOd@ Plural böd@ bÖd@ A similar drive to make the vowels of the preterite and present similar, but not identical, may have been at work in, e.g., lengthening the vowel of ba:r. Compare Table 4.22. This phenomenon is the opposite of that found in the past-tense marking of verbs such as bleed ∼ bled, prior to the Great Vowel Shift. The quality of the present and preterite vowels of bleed and bled were originally the same, and the quantity was changed in the preterite. The prevalence of this type of pasttense marking led to a productive pattern whereby the past tense was created by making the vowel of the preterite differ from that of the present in quantity, and remain the same in quality. This applies only to verbs ending in dentals and is discussed in further detail in Chapter 5. In the case of bra:k, the method of past-tense marking is to make the vowel of the preterite differ from that of the present in quality, and remain the same in quantity. Table 4.22: Middle English Leveling Before leveling After leveling Present Preterite brE:k@ brak brE:k@ bra:k I argue that inter-paradigmatic analogy was at work in the selection of the variant with /O:/. In Classes I, II, IV, and V this vowel arose through two separate phonological changes: the unconditioned shift of OE /a:/ to ME /O:/ in the Class 127 I preterite singular, and the open-syllable lengthening of /o/ in the participle of classes II, IV, and V. When the participial /O:/ was spread to the preterites of these latter classes, /O:/ was found in the preterites of 28 of 101 verbs examined by Long. It became an effective marker of past tense. Neither of the other two long vowels that were possible in Class IV and V preterites, namely /E:/ and /a:/, had so broad a distribution as /O:/. The former was not found in Class I preterites, and it would have led to homophonous presents and preterites in verbs without final dentals. The latter was found neither in Class I or II, except where extended on occasion by analogy with Class IV and V verbs. Selecting the variant with /O:/ in many verbs created a set of preterites with high type frequency, which reinforced their salience as strong verbs. According to Krygier (1994: 248-49), LC verbs were statistically favored to acquire weak past tenses in the 13th and 14th centuries, based on the following figures. 18 out of 30 LC strong verbs, or 60%, exhibited weak past tenses in the 13th century, compared to 81 out of 223 strong verbs of all other types, or 36%. In the 14th century, 27 of 28 LC strong verbs, or 96%, exhibited weak past tenses, compared to 132 out of 202, or 65%, of all other strong verbs. Chi-square tests show that the proportion of LC strong verbs with weak past tenses is statistically significant at the 90% confidence level. If my hypothesis is correct, and the lack of robustness of their strong inflection has less to do with vowel length, then this early date means a distributional account of LC weakening can be excluded. In the 13th century, most of the phonological lengthenings had only recently applied or were still ongoing, and the morphological lengthenings were only beginning to apply. Inter-paradigmatic pressure on verbs to have a long vowel in the strong preterite or become weak is not likely to have 128 been the driving factor, given that the proportion of preterites with long vowels is only 57%, hardly enough to drive out the 43% with short vowels. The LC verbs lead to the next section, a functional account of vowel length in strong verb preterites. 4.6.2 Functional Account The nature of strong verbs is to convey tense through a change in the stem vowel. It is in the interest of the listener, therefore, to be able to perceive well the difference between the vowel of the present tense and the vowel of the past tense. Research by Löfstedt (2010), Flemming (2004), and Steriade (2001) indicates there may exist contrasts between phonemes that are sufficient to convey lexical information, i.e. to create minimal pairs, but insufficient to convey grammatical information. For example, in Swedish, the non-neuter definite article, affixed to the noun, has two allomorphs, [en] and [n]. Löfstedt argues that there are instances in which the allomorph is selected according to its perceptual salience, rather than simply by phonotactics. For instance, the definite form of [søm:] ‘seam’ is [søm:en] rather than *[søm:n], even though [søm:n] is a phonotactically well-formed word in the language, meaning ‘sleep’. Therefore, phonotactics is not what is at work here. Neither is it mere sporadic avoidance of homophony, as the [en] allomorph surfaces systematically for all words ending in nasals, even those without potentially homophonous words elsewhere in the lexicon. In other words, the contrast [m] ∼ [m:n] is sufficient to make a lexical contrast between the nouns [søm:] ‘seam’ and [søm:n] ‘sleep’, but not perceptually salient enough to meet the higher standards for making grammatical contrast between the indefinite [søm:] ‘seam’ and definite [søm:n] ‘the seam’. 129 A similar phenomenon, wherein two vowels were sufficiently distinguishable to contrast lexical items but not sufficient to contrast different tenses of the same verb, may account for the tendency of verbs ending in liquid + consonant clusters to acquire weak preterites. The 13th century verbs that Krygier bases his conclusion on are the following: belZen ‘get angry’, berZen ‘defend’, bernen ‘burn’, bersten ‘burst’, delven ‘delve’, derven ‘labor’, ernen ‘run’, Zelden ‘yield’, helpen ‘help’, melken ‘milk’, murnen ‘mourn’, salten ‘salt’, spurnen ‘spurn’, swelZen ‘seam’, swelten ‘die’, walken ‘walk’, wherven ‘turn’, wurthen ‘become’. Of these 18 verbs, only 1 contains a cluster that triggers lengthening: Zelden. In the others, the vowel of the past tense is likely to have been of short duration, even relative to short vowels in other environments. There is evidence from phonetic studies showing that in most cases, the greater the number of tautosyllabic consonants in a syllable coda, the shorter the vowel is (Bell 1849, Elert 1964, Peterson and Lehiste 1960, Lindblom, Lyberg, and Holmgren 1981, Munhall et al. 1992). It is often assumed that the vowel is produced in an abbreviated fashion in order to keep the length of the syllables in e.g. car and carve roughly similar. Munhall et al. (1992) conducted a study to test this hypothesis. They compared the production of /E/ and /æ/ before complex codas and singletons. Because /æ/ is a low vowel, it involves greater jaw movement than /E/, so they tested whether the jaw opening was decreased before a complex coda relative to the aperture before a singleton. They found no difference, and they concluded that the shortening before consonant clusters is perceptual only, and the production remains the same. The perceptual shortening results from greater coarticulation between the end of the vowel and the beginning of the coda. The /r/ in carve is begun sooner than the /r/ of car. The gestural overlap of vowel and 130 coda consonant is what leads listeners to perceive the vowel as shorter in carve. In addition to an abundance of phonetic evidence from PDE for perceptual shortening of vowels before complex codas, we have indirect evidence for this phenomenon from earlier periods of English as well. Consider the ME rule of pre-cluster shortening, number [2] in section 4.2, which shows that shortening was present specifically in English. The exceptions to such shortening are obviously the specific clusters that combined with specific vowels to trigger what is traditionally called Homorganic Cluster Lengthening. In these 17 preterites—barn, barst, dalf, darf, arn, halp, malk, marn, salt, sparn, swalt, walk, wharf, and warth—however, the coda clusters are such that do not in Modern English permit, and perhaps never in the history of English have permitted, contrastive vowel length. (Stockwell and Minkova 1992: 198). Similarly, thanks to the rules of pre-cluster shortening and of open-syllable lengthening, we know that the vowel of the present and infinitive of LC-final verbs was shorter than the vowel of verbs in open syllables: hElpen vs. bE:ren. Hence, even though there was a phonemic difference between the vowels of 1st person sg. present tense /hElp(@)/ and of 1st person sg. preterite /halp/, the phonetic difference would have been much slighter than the phonetic differences of /bE:r(@)/ and of /bar/. It is impossible to carry out phonetic lab measurements on ME speakers, but we know that both vowels /E/ and /a/ were front, and one was low and one low mid. We know that speakers would have had very little time, due to the short duration of the vowel in the environment before a cluster, to perceive the difference between the two. The past-tenseness of /halp/ would therefore have been signaled much less robustly than that of any other strong verb. ME /E/ and /a/ present a case similar to Löfstedt’s (2010) findings in Swedish. 131 Here the two vowels were sufficiently distinct to carry lexical information, but the limited perceptual length before complex codas rendered them too similar to carry grammatical information. In other environments, they were able to carry grammatical information. Because the preterite /halp/ so strongly resembled the present /hElp(@)/, it had the potential to be misinterpreted by listeners as a weak preterite33 . Under the very conditions where /E/ sounded most like /a/, e.g. in fast speech or speech with background noise, a dental suffix would be the most difficult to perceive. A listener who heard /halp/ but perceived the vowel as /E/, might well interpret the form as /hElpt/, with the assumption that the dental, which had never in fact been pronounced, had been lost in transmission. The third consonant in the coda would be subject to gestural overlap with the preceding consonants, and would not be easily discernible under less than optimal conditions. If learners interpreted the underlying form as /hElpt/, they would begin to produce it themselves. This reanalysis would be aided by the fact that in ME, most strong verbs did have both strong and weak preterites. In some cases, the weak forms did not catch on, but in cases where the strong preterite could be interpreted as weak, the weak preterites would be more likely to catch on in higher frequency verbs, than in cases where the two variants were more distinct. By implication, short vowels in verbs such as sing ∼ sang ∼ sung would also have contributed to a decreased salience of strong preterites. There, the decreased salience was compensated for by close resemblance to many other such strong verbs. This class of verbs was robust enough in type frequency and phonological similarity that it was not in danger of suffering the same fate as help and the other verb ending in LC clusters. Furthermore, beginning in the 15th century, a phonological change occurred 132 that shifted /Er/ to /ar/. At this point, for 6 of these 17 verbs, namely berZen, bernen, bersten derven, ernen, and wherven, there would have been no difference whatsoever between the stem of the present and of the past. One must concede that English does permit inflections of this sort, as in cut ∼ cut. However, the only verbs that are invariant between the present and past are those that end in dentals, and they represent a different phenomenon: the fact that a final dental marks past tense, even if it is also the dental of the stem and is found in the present tense. This phenomenon is explored in greater detail in Chapter 5. Any remaining strong forms of these verbs, then, were even more likely than before to be interpreted as weak. 4.7 Conclusion ME lengthenings and shortenings of vowels paved the way for a substantial increase of the morphological disruption to the ablaut system that had begun in OE. The quantity changes created an imbalance within verbal paradigms, where the preterite was often the only member with a short vowel. Where possible, this situation was repaired by analogy, either by the lengthening of the vowel native to the preterite, or by the extension of a long vowel, different in quality from the preterite, from elsewhere in the paradigm. Where no long vowel existed in the paradigm, as in verbs ending in –LC clusters, no repair due to paradigm leveling was necessary, because all members had short vowels, nor was lengthening even possible in that pre-cluster environment. However, in these verbs, the vowel was phonetically even shorter than short vowels in other verbs, due to the tautosyllabic cluster in the coda. The duration of the vowel was insufficient for speakers 133 to hear clearly the quality of the vowel, and strong preterites had the potential of being misperceived as weak. Hence, verbs ending in –LC clusters were especially prone to becoming weak, beginning in the 13th and 14th centuries. Of the LC-final verbs, not one survives in the standard dialect as strong, although the highly frequent help retains some strong forms in other dialects, especially holp and holpen. At the end of ME, these phonological and morphological changes had resulted in a situation where most verbs exhibited a whole host of vocalisms in their paradigms. This state of free variation was reduced significantly in EMnE, and I consider it no accident that the dominant variants contained long vowels. Long vowels were preferred both for distributional—intra-paradigmatic and inter-paradigmatic—reasons, and for perceptual reasons. Eventually, what free variation still remained in the latter part of EME, such as bare/bore, was everywhere reduced in favor of /O:/, because of the great variety of verb classes that ended up with this vowel somewhere in their paradigm: classes I, II, IV, and V. 134 Chapter 5 Dental Stems 5.1 Introduction The classification of Present Day English (PDE) verbs is, as discussed in the introductory chapter, fraught with complexity. Verbs such as run ∼ ran are clearly strong, while verbs such as walk ∼ walked are clearly weak. Verbs that both change the vowel and add a suffix, such as keep ∼ kept, or that do neither, such as shut ∼ shut, are harder to classify. The present chapter deals with irregular verbs that end in dental stops, primarily the development of verbs such as shut ∼ shut. Keep ∼ kept, meet ∼ met, and shut ∼ shut all arose through the addition of the dental preterite suffix. Long vowels shortened before the cluster of the preterite, resulting in the vowel difference between present and preterite in keep and meet. In Middle English (ME) the final vowel of the preterite suffix was lost, and because English does not tolerate final geminates, the verbs with dental-final stems retain no trace of the preterite suffix. These steps are summarized in Table 5.1. The reason for focusing the present chapter on class (c) is that they introduced 135 Table 5.1: Dental-Final Developments Infin. (a) ke:pan ke:pan Vowel shortening Final ke:p syllable loss Degemination ke:p Pret. ke:pte kepte Infin. (b) me:tan me:tan Pret. me:tte mette Infin. (c) Suttan Suttan Pret. Sutte Sutte kept me:t mett Sutt Sutt kept me:t met Sut Sut a new means of marking the past tense, namely the zero allomorph. The vowel changes of (a) and (b), though not original to these verbs, was always present as a means of marking past tense in English. The chapter begins with a study of the development of the two competing mechanisms for marking a weak past tense: the variant with a “buffer” vowel between the dental of the stem and the dental of the preterite, and the variant without a buffer vowel. The latter changed in form from an overt suffix -te/-de to a zero allomorph, but as a class it remains distinct from the walk ∼ walked type. The question section 5.2 seeks to explain are twofold. First, the default preterite suffix for dental-final verbs in Old English (OE) had no buffer vowel. The default preterite suffix in PDE for such verbs, such as threaded, lauded, started, etc., has a buffer vowel. What caused this change? Second, what accounts for the specific verbs in PDE that irregularly mark their past tense with the zero allomorph? Section 5.3 treats the most productive classes of dental-final strong verbs: those like meet ∼ met that form their past tense by shortening the vowel of the present, and those that form their past tense with the vowel /æ/, as in spit ∼ spat. The final section deals with the origin of the widespread ME weakening of strong verbs, 136 and how dental-final verbs, a sort of intermediate class by their very nature, may have played a role. 5.2 5.2.1 Dental-Final Weak Verbs Proto-Germanic and Old English Proto-Germanic contained two weak preterite suffixes that are relevant to the development of the dental-final weak verbs. The first was -ede, traditionally classified as Class 1, and the second -ōde, traditionally classified as Class 2. Prior to OE, these two suffixes underwent vowel reduction. The long /-o:-/ of Class 2 was shortened. The short /-e-/ of Class 1 was syncopated in various environments, including following a dental suffix. Following syncopation, the dental stop of the suffix assimilated in voicing to the dental stop of the stem. Subsequent to the vowel reduction, weak suffixes appeared with two shapes: those with a vowel between the stem and the dental of the suffix, the “buffer” vowel, and the syncopated forms without such a buffer vowel. In Late Old English and Early Middle English (EME), further vowel reduction applied, such that the unstressed vowels of the suffixes began to be pronounced less distinctly, as indicated by the confusion in spelling. The outcome of this vowel reduction is represented as a schwa in Table 5.2. Table 5.3 shows the distribution of the two preterite suffix forms for verbs ending in dentals. The figures were gathered by searching the York-Toronto-Helsinki Parsed Corpus of Old English Prose for the orthographic sequences <dde>, <tte>, <d/tede>, <d/tode>, and <d/tade>34 . Because the corpus uses <+d> and <+t> to represent the eth and thorn characters, words where the initial <d> or 137 Table 5.2: Weak Preterites PGmc Early OE V Reduction Late OE V Reduction Class 1 non-dental *swerede ‘swore’ swerede Class 1 dental *hredede ‘saved’ hredde Class 2 non-dental *lufōde ‘loved’ lufode Class 2 dental *bodōde ‘announced’ bodode swer@d@ hredd@ luf@d@ bod@d@ <t> in the search string was preceded by <+> were removed from the lists. The figures for <dde> and <tte> were summed and placed in column 2, and the other six figures, representing preterites with a buffer vowel between the dentals, were summed and placed in column 3. This purely mechanical search by orthographical strings is not able to distinguish between sende, the past tense of sendan ‘send’, and lǣnde, the past tense of lǣnan35 ‘lend’. The form sende arises from *sendde, the syncopated form of *send-ede. Degemination applies after a consonant, geminates not being permitted in that environment. As a result, all preterites belonging to verbs ending in a consonant plus a dental are omitted from this search. It is therefore the case that the number of preterite allomorphs without the buffer vowel is somewhat higher than the number given in Table 5.3. Table 5.3: OE Preterite Allomorph Distribution Token frequency Percentage <-te>/<-de> (no buffer vowel) 2425 78% <-tVde>/<-dVde> (buffer vowel) 669 22% Given that the actual number of preterites in the corpus without the buffer 138 vowel is higher than 2425, something like 80% or even more of the verbs ending in dentals take the allomorph without a buffer vowel. This situation is in sharp contrast to PDE, where preterites such as knitted and threaded are the default. This chapter traces the development of the preterite allomorphy of the dentalfinal weak verbs. 5.2.2 Origins of Syncope First, it is necessary to ask why syncope took place after dental-final stems, when its usual environment was after a heavy stem. Wright (1954: 276-277) says merely that analogy with the heavy stems was responsible, without specifying further. Minkova’s account describes the effects in Late Old English of the syncope that took place in pre-Old English—the effect being the reanalysis of the boundary between stem and suffix—but not the causes of the pre-Old English syncope. Following the reanalysis, there is no syncope synchronically: the underlying form of the Late Old English preterite suffix is /de/. Syncope of the weak preterite vowel took place in several environments (Welna 1996: 52-59), and some of them are more difficult to explain than others. What concerns us here is the syncope after a dental-final stem, and that is simple to explain. There is ample evidence that the sequence TVTV, where T is a dental stop and V is a vowel, is dispreferred in languages. Menn and MacWhinney (1984) cite a plethora of examples in which a word, built according to the regular morphology of a language, would duplicate or give the appearance of duplicating an affix, and the word is therefore not produced. Speakers employ a variety of strategies in order to keep from producing such words. For instance, English speakers use haplology—the non-addition or deletion of an 139 affix—in the plural series instead of serieses*, and an avoidance strategy in the case of friendlily*. German speakers employ suppletion in choosing to add a diminutive -chen instead of -lein to words that end in /l/. Furthermore, children are later in producing such forms as pasted and kisses, which give the appearance of affix duplication, than in producing forms that do not give the appearance of affix duplication (Berko 1958; Bybee and Slobin 1982). Both morphological and phonological reasons have been proposed for why it is dispreferred, and the underlying factors are less easy to explain. Phonologically, the sequence TVTV has been interpreted as a violation of what is called the Obligatory Contour Principle (OCP). The OCP is a prosodic constraint that disprefers identical adjacent elements of any sort, whether syllables, tones, phonemes, or the like. Developed first by Leben (1973) to explain the avoidance of identical adjacent tones, it was extended by McCarthy (1986) to include such phenomena as the avoidance of C1 VC1 VC2 sequences in Semitic. Since then, much work has been done on developing the OCP, which is a universal yet violable constraint. Menn and MacWhinney (1984) take a morphological approach to the reluctance to produce such forms as friendlily*. Because the reluctance indubitably exists, yet is so frequently violated, Menn and MacWhinney refer to it as a weak universal. They assign it the name “repeated morph constraint” and give the formal definition that follows (529): “*XY, where X and Y are adjacent surface strings such that both could be interpreted as manifesting the same underlying morpheme through regular phonological rules, and where either (a) X and Y are both affixes, or 140 (b) either X or Y is an affix, and the other is a (proper subpart of a) stem.” Furthermore, while languages often avoid repetition of a morpheme36 , they also often deliberately generate repetition, in the process known as reduplication. For example, Ancient Greek verbs form their perfect by reduplication, e.g. present stem /lu:/ ‘loose’, perfect stem /lelu:/ ‘have loosed’. Yet in the very same language, /apoina/ ‘ransom’ is the result of haplologizing /apo + poina/ ‘from’ + ‘recompense’ (Liddell, Scott, and Jones s.v. apoina). Menn and MacWhinney conclude that the universal tendency is to avoid specifically accidental duplication, but not to interfere with deliberate reduplication as a grammatical marker. In the traditional classification of OE verbs into Class I and Class II verbs, it is Class I verbs that undergo syncope, while Class II verbs continue to violate the OCP and Repeated Morph Constraint. In pre-Old English, the syncope pattern can be explained by vowel quantity. The Class II preterite suffix *-ōd(Wright 1954: 277) would not have been subject to syncope, if we order syncope chronologically before shortening of unstressed vowels, both of which took place in prehistoric OE. The Class I preterite suffix *-id- always had a short vowel, and was therefore subject to syncope. After syncope ceased to be an active process, and after the environments were obscured, the unsyncopated vowel of Class II, in Minkova’s analysis, became reinterpreted as part of the stem. 5.2.3 M1 (1150-1250) The Penn-Helsinki Parsed Corpus of Middle English is divided into four periods, labeled M1, M2, M3, and M4. M1 covers the dates from approximately 1150 to 1250. During this period, various phonological changes applied that changed how the verbal system looked. The changes began with pre-cluster shortening of a 141 long vowel. Pre-cluster shortening affected verbs with long vowels in the stem and syncopated preterite suffixes, where the final consonant of the stem combined with the dental stop of the preterite suffix to create a cluster that triggered shortening. The result was the creation of vowel alternation–properly the marker of a strong verb–in originally weak verbs. The subsequent changes were the loss of gemination and final unstressed vowels. The result was that dental-final weak verbs with long vowels and syncopated suffixes had only a vowel change, with no overt suffix, to mark the past tense, and dental-final weak verbs with short vowels and syncopated suffixes had no difference between the present and past tense, except for personal inflectional endings. When a verb was borrowed, e.g. from French, or created from a noun or adjective, it became necessary to create a preterite. The preterite system that speakers had access to when generating a new preterite is shown in Table 5.4. Table 5.4: Dental-Final Developments Earliest ME me:tte ‘met’ mette Pre-cluster shortening Apocope mett Degemination met shutte ke:pte bodede ‘shut’ ‘kept’ ‘announced’ shutte kepte bodede swerede ‘swore’ swerede shutt shut swered swered kept kept boded boded An innovative dental-final weak verb had the option either of taking the default weak preterite suffix, or the more specific default dental-final weak preterite suffix. In the OE and earliest ME overall verbal system, the syncopated suffix occurred only in certain environments, and only on Class 1 verbs, while the unsyncopated suffix occurred on all Class 2 verbs and many Class 1 verbs. Within the set of dental-final verbs, in contrast, the syncopated suffix was the default. 142 The figures for the M1 suffixes occurring on dental-final verbs, taken from the Penn-Helsinki Parsed Corpus of Middle English, are shown in Table 5.5. I omit wend(e)/went(e) from consideration, because it accounts for nearly half the tokens of the verbs. Bybee (2001: 124-26) provides evidence that highly frequent forms tend to become isolated from other members of their families and to have limited impact on productive patterns. In this particular case, wend(e)/went(e) was so frequent that the preterite became dissociated even from the present wendan and associated instead with gangan. It is unlikely to have played any significant role in the overall system of dental suffix allomorphy. Table 5.5: M1 Preterite Allomorph Distribution Token frequency Percentage <-te>/<-de> (no buffer vowel) 287 88% <-tVde>/<-dVde> (buffer vowel) 39 12% The syncopated preterite allomorph continued its numerical dominance among dental-final verbs in the earliest stage of ME. In addition to tracking the history of the ratio between the two allomorphs, I also wish to determine which of the two was more productive. I operate on the assumption that speakers attempt to reproduce the exemplars stored in their head to the best of their ability. If they have memories of having heard the past tense of, e.g. write as wrote, they will produce wrote37 . If they have no memories of having heard the past tense of, say, slit, they will apply some productive pattern to it. Table 5.5 shows that the M1 balance of the allomorphs is in favor of the one without the buffer vowel, but it does not guarantee that speakers will always generate that one, or even that they will generate it something like 88% of the time. It is possible that every one of 143 those has been lexicalized, and when called upon to produce a preterite they’ve never heard, speakers will not use it. However, in the case of the M1 period, the dominance is sufficient that I find this highly unlikely, and I see no reason to reject the null hypothesis that the relative productivity has not changed since Late Old English. I therefore begin with the prediction that the allomorph without the buffer vowel will be the more productively used of the two. There are two reasons to include a study of productivity in the M1 period. One is simply to have the data to compare with later periods, to see if any significant change takes place. The other is that the methodology for determining productivity is shaky. If, in the case where a strong prediction can be made a priori, the results end up not supporting the hypothesis, it may be grounds for questioning the methodology rather than the hypothesis. The challenges of the methodology are manifold: the usual caveats about the representativeness of corpora for the spoken language, the fact that this particular period of English is poorly attested, and the extent to which the orthography is a reliable indicator of the pronunciation. In other weak verbs, there are cases where the preterite morpheme is spelled <ede>, but it scans as disyllabic. In that case, it is impossible to determine directly which vowel is omitted. Spellings such as <answerde> indicate that at least sometimes the buffer vowel is the one deleted in ME. These facts lead to the risk that a <dede> spelling in fact represents /(d)de/. Fortunately, the fact that affixes are more likely to have material deleted than stems means that a pronunciation of /(d)de/ for <dede> is less probable than /ded/, but it is still possible to adduce some indirect evidence relevant to the specific phenomenon of English vowel deletion. From nouns, it is possible to establish that the process of apocope was com- 144 pleted both earlier and more completely than the process of syncope. Syncope failed to apply regularly when the result would have been phonotactically illegal, as in fishes (fishs*). In the case of verbs not ending in dentals, the spellings of EMnE, preserved in PDE, indicate that even if <answerde> reflected a possible pronunciation, <answered> was the regular outcome. Disyllabic EMnE forms such plungèd38 exist, but forms such as plungde, or even the more phonotactically plausible learnde, do not. It follows that when <ede> is scanned monosyllabically, it is more likely to represent /ed/ than /de/. Finally, a high degree of consistency between ME orthography and PDE pronunciation in this one respect can be seen, in that dental-final verbs are virtually always spelled with a buffer vowel in ME, and in all the periods for which we have direct evidence for pronunciation, beginning with the grammarians’ commentary, are pronounced with a buffer vowel. Given the accumulation of evidence, I treat <ed(e)> as representing a suffix with a buffer vowel, while allowing that in some undeterminable but low number of cases it may in fact represent a suffix without a buffer vowel. As for the reverse scenario, there is no evidence anywhere in the language that a buffer vowel, when pronounced, would not be represented in the orthography. Hence, <de> can safely be taken to represent /de/ rather than /ede/. In the absence of controlled experiments on nonce words performed on native speakers, productivity is determined by the preterite assigned to the following classes of words: newly created denominal verbs, originally strong verbs made weak, loanwords, verbs inadequately attested in OE, and weak verbs with a preterite suffix that is not the expected reflex of their OE suffix. As an example of the last, the preterite of nēodian in OE was nēodede. The M1 preterite nett is considered a productive use of the suffix without a buffer vowel. Table 5.6 shows 145 the types and tokens of productive use of each of the two suffixes. Table 5.6: Productive allomorphy in M1 # % # % types types tokens tokens <-t(e)>/<-d(e)> (no buffer vowel) 181 64% 75 79% <-tVd(e)>/ (buffer vowel) 102 36% 20 21% A one-sample proportion z-test gives a p-value of less than .001 for the hypothesis that the preterite suffix without a buffer vowel was the preferred allomorph, which is in accord with the expected prediction. Later in the chapter the different treatment of French loanwords with respect to other verbs becomes important, so it will be instructive here to note the behavior of the French loanwords. The number of French loans recorded in the Penn-Helsinki Corpus for the M1 period is small. Only three types occur in the list of dental-final verb preterites: accord, wait, and rest. Accord and wait have buffer vowels in the preterite, and rest none: <reste> (2x). Between OE and M1, there is a drastic change in the number of syllables of verb stems. Comparing the preterites of dental-final weak verbs gathered from the York-Toronto-Helsinki Parsed Corpus of Old English Prose to the preterites of dental-final weak verbs gathered from the M1 period of the Penn-Helsinki Parsed Corpus of Middle English, I find a majority of the verb stems in OE to be di- or polysyllabic, and a majority of their descendants in the M1 period to be monosyllabic. I refer only to M1 verbs inherited directly from OE, for the purpose of determining whether the native grammar has changed or not. The ratios of the token frequencies are shown in Table 5.7. 146 Table 5.7: Syllable Count in Verb Stems # % # % monosyllabic monosyllabic di- or polysyllabic di- or polysyllabic Old English 1375 45% 1709 55% M1 282 94% 18 6% In OE, prefixes such as a-, be-, ge-, for-, and others were employed for altering the semantics of verbs. Bærnan meant to burn or set on fire, and forbærnan meant to burn utterly or consume with fire. This system of verbal prefixation began to be replaced by a system of phrasal verbs such as “burn up” (Hiltunen 1983). The causes are debated, and do not concern us here, but the effect is that most native verbs become monosyllabic, with prefixed forms such as “upset” surviving only when lexicalized, and not as the result of a productive system of prefixation. To summarize the findings from the M1 period, the preterite allomorph without a buffer vowel continues to dominate in verbs ending in dentals. Both allomorphs are extended in the generation of new forms, but the variant without a buffer vowel dominates in this as well. The major change has been that native verbs are now predominantly monosyllabic. French loanwords are attested in small numbers. 5.2.4 M2 (1250-1350) The period M2 of the Penn-Helsinki Corpus covers the dates from approximately 1250 to 1350. The most salient fact about the M2 period is the influx of French loanwords. A search for preterites of verbs ending in dentals yields accord, amend, arrest, comfort, confound, defend, delight, depart, dispute, distinct, haste, mount, 147 part, record, rest, tempt, torment, and visit. These verbs account for 18 of the 48 overall types, and 55 of the 310 tokens. Old French loanwords represent a significantly larger portion of the vocabulary in the M2 period than in the M1 period. A two-sample proportion z-test on the relative token proportions in Table 5.8 gives a p-value of less than .001. Table 5.8: Old French Dental-Final Verbs M1 OF types, % of total 11% OF tokens, % of total 3.00% OF tokens, # 9 # tokens total 322 M2 38% 18% 55 310 The Old French loanwords can be characterized as predominantly disyllabic, in contrast to the native words, of which only a single token in the list of preterites, <vp-braided>, has a stem of more than one syllable. The Old French loanwords, without exception, are assigned the preterite allomorph spelled with a buffer vowel. As stated above, we cannot guarantee that the buffer vowel was pronounced in all cases. However, the consistency of the orthography in representing the vowel in loanwords, in addition to the distribution of PDE, in which only two French loanwords, namely quit and cost, have a no-change preterite, makes it more than likely that the vowel was pronounced in all or nearly all cases in which it was spelled. Compare the Old French preference for the allomorph with a buffer vowel to the existing pattern in native words, shown in Table 5.9. In the M2 period, Old French verbs are assigned the default preterite allomorph for the overall verbal system, the suffix with the buffer vowel, not the default suffix for the specifically dental-final verbs. They are not sensitive to the phonological pattern among native words wherein verbs ending in dentals receive the allomorph 148 Table 5.9: Old French Dental-Final Verbs OF # tokens Native # tokens OF % tokens Native % tokens -t(e)/-d(e) (no buffer vowel) 0 198 0% 80% -tVd(e)/-dVd(e) (buffer vowel) 55 51 100% 20% without a buffer vowel. This is so despite the fact that the allomorph without a buffer vowel continues to enjoy some productivity among native words. For example, wed, which had the preterite weddede in OE and M1, appears as <uedde> in M2. In section 5.2.3 it was argued that <dde> never represents /ded(e)/; hence we take <uedde> to represent a syncopated form, the pre-form of PDE preterite wed. There exist parallels for this separate treatment of loanwords, e.g. Hebrew noun plurals (Becker 2009). Hebrew masculine nouns take the plural –im and feminine nouns the plural –ot. However, native masculine nouns that have /o/ in their final syllable are permitted to take the plural –ot. This is a productive pattern and is applied to nonce words in experiments. Loanwords, however, are not sensitive to this phonologically-based allomorphy. All masculine loanwords are assigned the plural –im regardless of their stem vowels. Becker attributes this dual treatment of native and loanwords to differences in stress. In the case of Old French loanwords, I submit that they are phonotactically different from native verbs in being predominantly disyllabic. They stand out as loanwords, and are thus not subject to all the same fine morphophonological distinctions as native words are. The foreign-sounding loanwords are shunted 149 overwhelmingly into a default category: the preterite allomorph with a buffer vowel. As in M1, we may wonder about the relative productivity of the two allomorphs in M2. This, in some ways, is even more difficult to measure. In M1, productivity was measured by counting forms that had suffixes that they did not have in OE. Limiting the count to words that appear in M2 with suffixes they did not have in OE or M1 leaves an extremely small data set, and that procedure is probably not reflective of true productivity. Consider a word such as fast. It had no buffer vowel in OE, and a buffer vowel in M1 and M2. The form fasted in M1 is certainly innovative, but what about M2? Perhaps speakers who produced fasted in M2 produced it because this was the form stored in their memory, which had been passed down from generation to generation since M1. Or perhaps it was infrequent, and they were generating a new preterite because their memory contained no exemplars of an existing preterite for fast, or perhaps it contained both faste and fasted. This is the same problem that we face when we take the PDE preterite of an infrequent verb, such as slung, to be conservative in its morphology because sling was an OE strong verb of Class III. Sling happens to have been a very infrequent verb, with no instances of slungon or slungen attested in the OE corpus. It survived largely because when speakers were called upon to generate a past tense for it, not having heard one recently, they had Class III as a productive pattern to fit it to. Had it both been infrequent and belonged to a rare pattern, its original inflection would not likely have survived. Likewise, infrequent verbs, or verbs for which competition existed, such as put ∼ put and put ∼ putted, partly retained their inherited past tenses, and partly had new past tenses generated, which might or might not match their inherited past tenses. It is with great caution, then, that 150 I compute productivity for M2 just as in M1, disregarding the fact that some M2 forms might have been simply inherited from M1. Table 5.2.4 shows the results. Note that these include only OE and Old Norse—because Old Norse phonotactics were similar to OE—verbs. A one-sample proportion test for the difference in token proportions gives a p-value of .03 for the hypothesis that the proportion of forms with a buffer vowel is significantly greater than the proportion of forms without a buffer vowel. Table 5.10: Productive allomorphy in M2 # % # % types types tokens tokens -t(e)/-d(e) (no buffer vowel) 3 23% 11 35% -tVd(e)/-dVd(e) (buffer vowel) 11 77% 21 65% I submit that the frequency of the sequence –ded(e)/-ted(e) had increased dramatically due to the influx of French words, all of which were assigned the suffix –ed(e). This difference can be viewed in two ways. One, the number of dental-final verbs with a buffer vowel in the suffix increased. Two, and I believe more importantly, the productivity of the suffix with the buffer vowel increased. The latter can be illustrated using Fisher’s Exact Test on the 2-by-2 table in Table 5.11, comparing the distribution of productive tokens in M1 and M2 taken from Tables 5.6 and . The resulting p-value is less than .001. As a result of the increase in productivity of the form with the buffer vowel, the sequence –tede/-dede was no longer so rare in the language. These changes, combined with the fact that alternation already existed in native English words, as in putte vs. puttede39 , led to the suffix with a buffer vowel becoming the default 151 Table 5.11: M1 and M2 Productive Allomorphy -t(e)/-d(e) (no buffer vowel) M1 75 M2 11 -tVd(e)/-dVd(e) (buffer vowel) 20 21 even for verbs ending in a dental. This development was part of a more general ME tendency, explored by Minkova (to appear), for the weak preterite allomorphy to reflect the phonotactics of the stem. To summarize the M2 findings, disyllabic French loanwords abounded. They ignored the allomorphy that was sensitive to the final consonant of the stem, and all took the preterite suffix with a buffer vowel. This, combined with the existing free variation of suffixes, led to a shift in the default from –d(e) to –ed(e). The latter remains the default suffix for PDE dental-final verbs. 5.2.5 M3 and M4 (1350-1500) The period M3 of the Penn-Helsinki Corpus covers the dates from approximately 1350 to 1420, and M4 the dates from 1420 to 1500. I treat them as a unit for two reasons. First, none of the relevant properties, such as importance of French loanwords or syllable count of French vs. native verbs, differs in any interesting way between M3 and M4. Second, combining the data allows for a sufficiently large sample size to obtain statistically significant conclusions. During the M3 and M4 periods, just as in M1 and M2, the preterite suffix without a buffer vowel predominates among native dental-final verbs, and the suffix with a vowel among dental-final verbs borrowed from French. These results are summarized in Table 152 5.12. Table 5.12: M3 and M4 Allomorphy # % # % of of of of native tokens native tokens OF tokens OF tokens -t(e)/-d(e) (no buffer vowel) 9441 90% 47 6% -tVd(e)/-dVd(e) (buffer vowel) 109 10% 716 94% Beginning with the M3 period, if not in fact with the M2 period, there is no sure method for determining productivity of suffixes in native dental-final. Employing the same method for M3 as used above for M2 and M1 yields 71 tokens of productive –ed(e) and 123 tokens of –de/-te. Of the latter, 82 are accounted for by the verb put, which is surely of sufficiently high frequency that its preterites are inherited from earlier periods more often than generated afresh. Yet alternation continues to exist: e.g. cut/cutted, cast/casted, set/setted. The safest method is to look at the verbal system as a whole, and to interpolate a description of the M3 period from facts known about the surrounding chronological periods. Minkova (to appear) finds that by the second half of ME, the weak preterite allomorphy is governed largely by phonotactics. The influx of French verbs appearing in M2 led to the buffer vowel suffix being favored for dental-final verbs, and we saw the preference change even for native words. The preference for the buffer vowel continues in PDE, though generation of preterites such as knit is still possible. In the second half of ME, it is reasonable to conclude that freshly generated preterites could take either suffix, though the buffer vowel was preferred. Two features of M3 and M4 are different from previous periods. For one, the proportion of French loanwords in the lexicon increases, shown in Table 5.13. They 153 make up more than half the types of dental-final verb preterites, and 25-30% of the tokens. The disparity between types and tokens is caused by the high token frequency of native words, which form the core vocabulary of the language, especially went, which accounts for half the native tokens. Many individual French40 words were borrowed and used infrequently, sometimes only in writing for the purpose at hand, hence the high type frequency. The decline of French as a spoken language is perhaps reflected in the slight decline of the proportion of tokens between M3 and M4. Table 5.13: Old French Dental-Final Verbs in ME M1 M2 M3 M4 OF types, % of total 11% 38% 56.00% 64% OF tokens, % of total 5% 18% 30.00% 25% Another interesting pattern in the French data lies in the forms that have a preterite with no buffer vowel. The forms without a buffer vowel constitute a higher percentage of the monosyllabic verbs than of the polysyllabic verbs. In Table 5.14, the percentage of monosyllabic verbs that have no buffer vowel is shown to be roughly twice that of the di- and polysyllabic verbs. Recall that in the M1 period, the only French dental-final verb to have a suffix without a buffer vowel was the monosyllabic rest. Table 5.14: M3 and M4 Syllable Count Vis-à-Vis Preterite Allomorphy # types w/o buffer vowel monosyllabic 841 di- or polysyllabic 1242 # tokens w/o buffer vowel 19 28 % tokens w/o buffer vowel 10% 5% With the combined corpora of the M3 and M4 periods, a z-test shows that 154 p < 0.05 for the difference in proportions, so the difference can be taken to be statistically significant. Monosyllabic dental-final verbs borrowed from French are more likely to have a preterite with no buffer vowel than disyllabic or polysyllabic verbs are. This provides further support for the hypothesis that it was the overwhelming disyllabicity of the French loanwords that caused early dental-final verbs to be assigned to the default category of preterite-marking. It is important to remember that the allomorph without the buffer vowel is not exclusive to monosyllables at any stage. Prefixed native verbs take this suffix from the earliest ME to PDE—e.g. upset—and as Table 5.14 shows, disyllabic French loanwords might use this suffix as well. 5.2.6 Early Modern and Present Day English Increased standardization of the English language has led to reduced variation among the weak past tenses. Among dental-final verbs, however, a fair amount of variation remains. Merriam-Webster lists, for example, fit/fitted, bet/betted, knit/knitted, and Pinker (1999: 61) discusses in addition pet vs. petted. Other verbs such as whet/whetted have shown alternation in EMnE but do not usually alternate at present. For this section, I refer to the continuation of the verbs with no buffer vowel in the preterite suffix as the “no-change” verbs, due to the phonetic loss of the final schwa and degemination of the geminate dental stop. The suffix itself is the zero allomorph. ME putte > PDE put. Preterites with the full suffix, such as knitted, are referred to as “overtly marked” preterites. Continuing the theme of the present work, we may examine the set of verbs that has displayed alternation between no-change and overtly marked preterites in English, and seek to explain which verbs ended up with which suffix in PDE. Keep 155 in mind that the default is now overtly marked preterites, yet no-change preterites remain a sufficiently large class to attract new members. For the set of verbs that have a history of alternation, I use the list of PDE no-change preterites from Quirk et al. (1985: 110-122), the Penn-Helsinki parsed corpora of Middle English and of Early Modern English, and the irregular verb lists from the eighteenthand nineteenth-century grammarians in Greenwood (1711), Kirkby (1746), Fisher (1750), Lowth (1762), Ward (1765), Fell (1784), Smith (1864), and Greene (1867). The list of collected verbs is presented in Table 5.15, along with their frequencies from the CELEX database (Baayen et al. 1995). Judgments of readers as to the preterites used in their own speech may vary. 156 Table 5.15: PDE Allomorphy of Dental-Final Verbs Zero Allomorph put let set cut hit spread shut hurt beat cost cast burst split bet thrust shed quit spit slit bid knit shit wet wed rid Average CELEX preterite frequency 1367 782 520 325 160 132 129 108 103 72 63 55 54 41 27 24 21 7 6 6 5 3 2 1 0 161 Overtly marked CELEX preterite frequency 43 wanted 1200 started 726 lifted 146 granted 118 fitted 60 rested 54 trusted 53 parted 40 heated 32 dreaded 16 knitted 12 roasted 12 shrouded 11 sweated 10 shielded 8 fretted 5 rotted 5 wafted 5 whetted 2 fasted 1 voided 1 wedded 1 thirsted 0 Average 109 In a frequency-based approach, irregular forms are expected to have higher frequency than regular forms. This is borne out by the frequency counts in Table 5.15, where the average frequency of the irregulars is 161 and the regulars is 109. Additionally, the lower frequency verbs in the no-change column are more subject to alternation: bet/betted, spit/spat, bid/bad(e), knit/knitted, shit/shitted/shat, wet/wetted, wed/wedded. Unlike the strong verbs, where most irregular forms are 157 inherited from OE, only dread, heat, knit, sweat, shield, fast, thirst, set, spread, and shut had the sequences –tte or –dde in OE. The only case where an OE verb with –ede has a no-change preterite in PDE is wed, which also permits wedded. Another pattern in the no-change verbs is apparent: a short vowel followed immediately by the dental stop, with no intervening consonant. Of 25 no-change verbs, 20, or 80%, have simple codas, compared to only 12 simple codas, or 52%, among the 23 verbs with overtly marked preterites. The exceptions are beat, cast, cost, hurt, and thrust, which have complex codas and no overtly marked preterite, and dread, knit, sweat, fret, rot, fit, and whet, which have simple codas and only overtly marked preterites in CELEX. Of those, Merriam-Webster lists no-change preterites for fit and sweat. The frequency of the irregular exceptions is expected to be higher than the regular exceptions, and indeed, the average frequency of beat, cast, cost, hurt, and thrust is 64, and the average frequency of dread, knit, sweat, fret, rot, fit, and whet is but 16. It is not possible to explain the outcome of each and every verb, but the general tendencies can be summed up. The default suffix for dental-final verbs gradually in ME became the one with the buffer vowel. However, the suffix with no buffer vowel, which became the zero allomorph, remained and remains a viable option. It may be attached to monosyllables ending in a dental stop, and is more likely to catch on and become the usual form if the verb has a short/lax vowel followed immediately by the dental. This pattern stays true to its ME origin, in that the reason most no-change verb preterites have a short vowel is that they originated in a class of verbs to which the rule of pre-cluster shortening was applied, followed by a loss of the preterite suffix. If the stem vowel was long, the result was ablaut, as in feed ∼ fed. If the vowel was short, as in put ∼ put, a no-change verb arose. 158 The morphological category of unmarked preterites was thus associated with the phonological feature of short vowels from its earliest history. The category has proved resistant to the entry of members with long vowels. The only instance of a long vowel in PDE is in beat. The irregularity of beat was commented on by Walker (1791), who records that a short-vowel preterite bet existed at the time in Ireland, but was not considered good usage in England. Walker correctly observed that no-change verbs are dispreferred by speakers because they are not overtly marked for tense, which creates an obstacle to comprehension44 . The distributional account presented above, namely that the influx of French verbs changed the proportions of preterite suffixes used with dental-final verbs, may have been what initially triggered the English speakers’ preference for the suffix with the buffer vowel, but the functional account surely contributed. The loss in later ME and in EMnE of final weak syllables and eventually of most of the personal endings from the verb was what led the competition between two variant suffixes to become a competition between an overt suffix and a zero allomorph. This created a new means of marking past tense in English, and it created one more reason to disprefer, though not to eliminate entirely, the shut ∼ shut type. The competing principle Walker discusses is conservatism of inherited forms: everyone says beat with a long vowel, so everyone continues to say it. In Section 5.2.2 an additional competing principle was seen that allows no-change preterites to exist: the violations of the Repeated Morph Constraint and/or the OCP by regularly marked forms such as beated. These two principles continue to be in competition as speakers decide between pet and petted.45 159 5.3 Dental-Final Strong Verbs In the history of English, there have been two major productive patterns among verbs that end in dentals and form the preterite by changing their vowel. One is the pattern whereby the vowel of the present and preterite are historically the same in quality and differ only in quantity. The other pattern is a preterite ending in /æt/. These have their origin in weak verbs with a long vowel in the present, which was shortened before the cluster formed in the preterite, e.g. feed ∼ fed from ME fēdan ∼ fedde. They thus share an origin with the no-change verbs, which differed from these verbs in having a short vowel throughout the paradigm: set ∼ set from setten ∼ sette. The Great Vowel Shift eliminated the qualitative similarity between the vowels of the present and of the preterite, by shifting the long vowels and leaving the short vowels untouched. Thus /fi:d/ ∼ /fEd/ arose from /fe:d/ ∼ /fEd/. The class itself, however, remains productive. In Chapter 4, it was argued that, as a rule, strong verb preterites prefer long vowels to short. One of the two systematic exceptions was verbs that end in dentals. The product-oriented schema that prefers short vowels before dentals arose through the pre-cluster shortening that produced such preterites as fed and set. It was shown that participles with short vowels do not replace preterites with long vowels, but rather the reverse. Thus participial /bO:r/ replaced preterite /bær/, but the Class I preterites such as /drO:v/ remained. In the case of dentalfinal Class I verbs, short vowel preterites abound. The lists of the eighteenth- and nineteenth-century grammarians include such patterns as write ∼ writ (Greenwood 1711; Fisher 1750), ride ∼ rid (Greenwood; Fisher; Fell 1784; Greene 1867), and stride ∼ strid (Smith 1864; Greene). Additionally, the OED records glid from the 160 17th to 19th centuries and notes that it might be used today “without causing surprise” (s.v.), and smit in the 16th and 17th centuries. There are no examples in Greenwood, Fisher, Fell, Green, Smith, Ward, Lowth, or Kirkby of preterites ris, striv, driv, shriv, thriv, or shin, though ris has been produced as a reduced participle46 . The distribution is best explained by the two competing principles of preferring long vowels in strong preterites, and preferring short vowels before dentals. The most prescriptive of the grammarians, Lowth (1762), includes none of fit, writ, strid, rid, and glid, indicating that perhaps the conservative desire of the prescriptive grammarians to retain the inherited pasts and ignore recent analogical creations played a role in the survival of wrote, strode, and rode. Greene (1867) likewise disapproved of smit and fit. The only PDE verb for which the preterite ends exclusively in /æt/ or /æd/ is sit ∼ sat. Spit has the alternate preterite spit, and shit the preterites shit and shitted. Bid has the alternate preterites bid and bade /beid/, which may also be pronounced /bæd/. In the case of bid ∼ bad(e) and sit ∼ sat, the /æ/ preterite is the inherited one. The inherited preterite of spit is spit, and the preterite spat is attested in the 16th century. Shit should conjugate shite ∼ shote ∼ shitten, coming as it does from the OE Class I verb scītan. The first quotation of shat in the OED dates to 1929, but because this is a taboo word, the appearance of forms in writing may significantly postdate their emergence in speech. Other verbs also acquired preterites in /æt/ that were not original to them. Put, in the north of England, acquired pat and pitten/putten in the 15th century, hit acquired hat and hitten in the 17th, and knit acquired knat in the north of England at least by the 19th century, judging by the earliest quotation in the 161 OED. 5.4 5.4.1 Causes of the Strong ∼ Weak Instability Shift or Merely Flux? A frequent premise of works on the history of English strong verbs is that they are doomed to become weak. For example, Lieberman et al. (2007) present the development of irregular verbs as a steady-state decay, akin to radioactive decay. Fertig (2009) challenges Lieberman et al. on this premise. He enumerates the verbs that have been misclassified as examples of the shift from strong to weak, and having eliminated these misclassified verbs, he recomputes the extent of loss of strong inflection. Beginning with a set of 293 strong verbs in OE, he finds the following outcomes: 103 suffered lexical loss without having become weak. 65 remain entirely strong in PDE. 2347 represent the falling together of a strong and weak pair, resulting in a weak verb 2848 became weak, but retain some irregularity in PDE. 7449 became completely regular weak verbs In the most extreme case, then, 28 + 23 + 74 became weak. Subtracting the 24 that underwent lexical loss, there are a total of 101 weak and 65 strong strong in PDE from the set of OE strong verbs. This makes a 60% to 40% balance in favor of weak, and does not even include the examples given by Fertig of the reverse trend: weak verbs becoming strong. Fertig’s conclusion is that analogical change is not unidirectional, inevitably leading to the shift from strong to weak; there is 162 some exchange in both directions, and more robustness on the part of strong verbs than has previously been recognized. In this section, I address Krygier’s treatment of this premise. The title of his book, The Disintegration of the English Strong Verb System (1994), highlights his belief in the doom of the strong verbs. Consider the statement that “All indications are that in the 14th century strong verbs were proceeding fast on the road to oblivion” (194). This statement is not borne out by the fact that some 40% of the verb set remain entirely strong in PDE, and it derives from a methodological error on his part. Krygier considers the mere occurrence of a weak preterite or participle equivalent to the loss of strong inflection. Any verb that exhibits a weak form in ME is said to have “undergone the shift (from strong to weak).” If this were the case, we would expect virtually no strong verbs to have survived to PDE. In truth, however, a ME verb may display only a very few weak forms among a predominance of strong forms, and there is no reason to expect the same outcome from this verb as from a verb that displays only weak forms in ME. This is one of the pitfalls of Krygier’s approach, which looks only at types, never at tokens. More accurate is Welna’s account: “The most important development in the strong verb system was their partial [SB: emphasis mine] shift to weak verbs. Although in ME only a few former strong verbs became totally weak (cf. chew, dive, etc.), almost all verbs developed weak endings which survived in parallel use with the strong forms. In their subsequent development now the weak, now the strong type prevailed, but sometimes both types continue in Standard English” (1996: 120). Though Krygier’s presentation of the ME data suffers from a serious flaw in ignoring the fact that not all verbs exhibiting weak forms became weak in PDE, 163 it is possible to reinterpret the strong-to-weak “shift” as a flux or instability and carry on. Krygier’s work asks what the causes of the shift are; we may ask what the causes of the sudden instability are, and this is an equally valid, albeit less drastic, question. It is not the case that all strong verbs in OE or PDE exhibit this alternation with weak forms, so why did the ME strong verbs fluctuate to such a degree? The many language-internal factors behind strong and weak inflection have been explored in this dissertation. However, the sudden change between the state of strong verbs in OE and in EME coincides with the Norman invasion, and calls for language-external factors to be explored as well. Three major hypotheses have been offered for the sudden instability in ME. One proposed factor is the influx of French verbs, which were nearly all inflected weak. Another is the hypothesis that native speakers of French mislearned English, being led astray by the similarity between dental-final strong verbs and the weak dental preterite. The third is the disruption of the OE literary standard by the Norman invasion. 5.4.2 Influx of French Loanwords The fact that the Norman invasion had a huge effect on the vocabulary of English is inarguable, as is the fact that virtually all verbs borrowed from French were inflected weak. At first glance, it was entirely possible that enough verbs were borrowed from French that the ratio of weak to strong verbs increased substantially. As a result, more native English verbs may have come to be inflected weak than otherwise would have. This hypothesis, proposed by Strang (1970), is also accepted by Nielsen (1997) in his review of Krygier’s monograph. It resembles the hypothesis of the present chapter, that the influx of French dental-final verbs 164 inflected with a buffer vowel in the weak preterite led to more native words being inflected that way. However, the hypothesis depends on the overall number of borrowed French verbs being sufficiently high to change the existing ratio of strong ∼ weak, a hypothesis that my research has not borne out. The vast majority of French loanwords were nouns and adjectives. Nouns and adjectives are in general more frequently borrowed than verbs (van Hout and Muysken 1994), as their referents are easier to identify. Pointing to a verb is more difficult. Dekeyser (1986) computes the impact of Romance loans in the ME lexicon, and finds that only 10% of Romance borrowings were verbs. Using LAEME, I computed the proportion of strong and weak verbs for EME by searching the dictionaries of forms for the tags “vSpt” (verb in the strong preterite) and “vpt” (verb in the weak preterite). The result roughly represents the number of types in each category, although prefixed verbs are counted as separate types. Quirk and Wrenn (1957) computed the proportion of strong and weak verbs for OE. The results are presented in Table 5.16. Table 5.16: Proportions of Strong and Weak Verbs % strong verbs % weak verbs Old English Early Middle English 25% 27% ∼ 75%50 73% The difference between the proportions of strong and weak verbs in OE and EME is not significant. Moreover, it should be taken into account that all strong verbs in LAEME that have weak forms are counted in both categories, so the weak verb percentage is slightly higher as a result. The fact that the proportions have not changed significantly can be attributed to two factors. First, the relatively 165 low number of verbs that were borrowed, as already discussed. Second, lexical loss among verbs inherited from OE is predicted to be higher in weak verbs, which contain more low frequency members. 5.4.3 Normans and Dental-Final Verbs A lexical disturbance of the balance by loanwords is unlikely to have triggered the major instability of ME strong verb inflection. Krygier’s hypothesis depends even more directly on the influence of the Normans. He proposes that the Normans learning English realized that the majority of past tenses ended in dentals. This led them to misinterpret some dental-final strong verbs as weak. For example, the strong preterite plural of bītan ‘bite’ was biton. Were it a weak verb of Class I, it would be bītton, with, perhaps, pre-cluster shortening: bitton. Krygier proposes that native Anglo-Saxon speakers then heard the members of the prestige register of English assigning weak inflection to what they, the native speakers, knew to be strong verbs. The native speakers took this to mean that strong verbs were unfashionable, and they began to produce weak forms for all strong verbs. Attributing the source of any major grammatical change to the Normans is considered a dicey prospect, as the Normans at their peak constituted at most 10% of the population, and probably far less than that (Berndt 1965, in Lass 1969). Krygier attempts to get around this problem by positing a conscious, sociolinguistically-driven phenomenon. His hypothesis does not require native speakers of French to have imposed their own French grammatical structures on English, but only to have learned English incompletely for English-internal reasons, and to have been imitated by native speakers, who formed the overwhelming majority of the population. It does not require a majority of speakers to have had 166 any familiarity with French at all, only contact with French speakers speaking English. However, the plausibility of this prestige register’s existence having an impact of this extent on the grammar has been called into question (Nielsen 1997). Even positing its existence for the sake of argument, the impact Krygier wishes it to have had on the grammar of English is implausibly far-reaching. I find it possible that the Norman French speakers learning English as adults would have overapplied the weak suffix. I find it conceivable that some native speakers of English, wishing to facilitate communication with those who understood English poorly, may have deliberately overapplied the weak suffix. However, the idea that all these native speakers then went home and in front of their own children, who were not learning French as a native language, produced weak forms because the Norman upper class did, is an unmotivated leap, given the small proportion of French speakers in England. Thomason and Kaufman (1988) have presented evidence that in situations where one language group takes over another, lexical influence is more likely to move from the conquerors to the conquered, and grammatical influence from the conquered to the conquerors. Thus, they say, even if we did not know a priori that French formed a superstratum of English at one time, we would have reason to believe it from the lexicon (116). The fact that the Normans constituted such a very small part of the population is a major stumbling block for the hypothesis of direct grammatical impact on the strong verbs. Moreover, a passage from Lass (1987: 60) illustrates a major weakness in the prestige hypothesis: the prestige language of the upper classes was French, and to a lesser extent, Latin, not English. The written texts of ME appear in the 167 dialects of those writing them, until the 14th century, when speech proper to the area around London began to be perceived as a standard dialect. If there was no written standard for English, still less was there likely to be a spoken prestige register. If the upper classes considered French to be the prestige language, and did not value English enough to learn it properly, as Krygier hypothesizes, still less would the lower classes value the broken English of the upper classes and imitate in their own speech the errors made by Normans. 5.4.4 Interruption of the Scribal Standard The third explanation for the instability, the interruption of the English literary standard by the Norman invasion, has been proposed in two different forms. Faiß(1977) asserts that the written poetic standard of OE was conservative. Baugh and Cable (1978) emphasize the lack of education of English speakers after the Conquest, which Krygier, rightly in my opinion, does not accept. Literacy was far from universal in the OE period, and it is improbable that the speech of the average Anglo-Saxon was influenced by education and a written standard. What is probable is that the written records of OE do not reflect the speech of the average Anglo-Saxon at the time, and that this is the reason for the sudden instability of verbal inflection in ME. In the first place, the written standard of OE may be taken to be quite conservative, especially in view of the high degree of orthographic consistency relative to ME—not relative to PDE. In the second place, the majority of the extant OE corpus is from West Saxon, which was not the direct ancestor of ME dialects. As Krygier demonstrates (see the introduction and Appendix 1 of this dissertation), there was a certain amount of strong ∼ weak alternation already present 168 in OE (1994: 59-65). We may assume that the alternation was greater in the spoken language. Writings in OE do not reflect actual speech as closely as writings in ME. Furthermore, Krygier, following Seebold (1970), shows that the strong ∼ weak alternation was greatest in the Northumbrian dialect. This may reflect Old Norse influence, as Krygier argues, or it may reflect a state of affairs where West Saxon was more conservative than other dialects, causing greater fluctuation in ME than the extant corpus of OE would otherwise lead us to expect. If the instability of inflection began in OE and was somewhat more prevalent than we can tell directly from OE, we can posit language-internal reasons for it to have escalated in spoken ME. Bloomfield writes, “We do not know why speakers sometimes utter new combinations instead of traditional forms, and why the new combinations sometimes rise in frequency...It seems that at any one stage of a language, certain features are relatively stable and others relatively unstable. We must suppose that in the sixteenth century, owing to antecedent developments, there were enough alternative plural-forms (say, eyen : eyes, shoon : shoes, brethren : brothers) to make an innovation like cows relatively inconspicuous and acceptable. At present, an innovation like foots seems to have no chance of survival when it is produced from time to time” (1933: 409-410). He continues along similar lines: “Some [Middle English] nouns fluctuated: [feld] ’field,’ plural [’felda] or [’feldas]. We do not know the origin of this fluctuation, but, once granted its existence, we can see in it a favoring condition for the spread of the [-as]-plural. A neologism like [’sunas] instead of older [’suna] ’sons’ would perhaps have had no better chance of success than a modern foots, had it not been for the familiar fluctuation in cases like the word ’field.’ ” (1933: 409-410)51 169 For whatever reason, the instability that began in OE spread to include nearly every ME strong verb. The alternation in one verb permitted the alternation in another verb to pass as legitimate free variation rather than a mere speech error. If Krygier is correct, and dental-final strong verbs in the 12th century are more likely to appear with weak forms than verbs of other stem types, this need not only have pertained to non-native speakers. If the alternation between strong and weak was already sporadically in place in OE, incipient degemination in EME may have led native speakers to the same analogy that Krygier attributes to the Normans. This development may have been what opened the floodgates, allowing the sporadic OE strong ∼ weak instability to spread to nearly every verb in ME, without the need to invoke the Normans as the immediate trigger. Perhaps partly because this instability ran its course naturally, and no doubt partly because of the rise of a standard register and the idea that some linguistic variants were superior to others, the amount of inflectional variation in the strong verbs was much reduced in Early Modern English. Some free variation remains, e.g. spit/spat and dived/dove, and dialectal variation remains, but Welna’s summary of the ME state of affairs, that nearly every strong verb had a competing weak ending, no longer applies to English, at least in the standard dialect. 170 Chapter 6 Quantification 6.1 Introduction This chapter synthesizes the conclusions reached in the previous chapters. First a brief summary describes how the relevant factors combined in the grammar to determine the inflectional outcome of the strong verbs. Then a statistical model that quantifies these factors is described, and the factors are analyzed in terms of whether the model finds them to be significant or not.52 In the process of analyzing the model, the interaction of different factors is seen. Finally, I use the model to test the possible effect of a factor deemed relevant by Welna (1991), namely the presence of a bilabial in the coda. Chapter 2 studied the effects of frequency. The effects of high token frequency on preserving strong inflection have long been recognized. High frequency verbs are on the whole more conservative in their morphology and low frequency verbs less conservative. One contribution of this work has been to make full use of frequency data from historical corpora that have recently become available. The Linguistic 171 Atlas of Early Middle English (LAEME) in particular is a great benefit, as it opens up to us a period previously the most difficult to study, despite its importance as a turning point for many aspects in the history of English. Previous studies on the history of English have not had access to such easily accessible corpora, and studies carried out by theoretical linguists have largely dispensed with the historical data. One study that I am aware of, Hare and Elman (1995), has made use of historical frequency data. Comparing a concordance of Old English (OE) (Di Paolo Healey and Venezky 1980) and a concordance of the works of Chaucer (Tatlock and Kennedy 1963), they found no significant changes in frequency. They did not compare these data to Present Day English (PDE) data, which I have done using the CELEX (Baayen et al. 1995) database. My study found that the relative frequency of most verbs was stable over time; however, several verbs have either increased or decreased in frequency. In some cases, e.g. come, the PDE inflection corresponds with the PDE frequency, while in others, e.g. slay, the PDE inflection corresponds with the Middle English (ME) frequency. For example, slay is now much less frequent, having been replaced by kill, yet it remains strong. In contrast, warp was replaced by throw and became weak. One of the contributions of this dissertation is to identify such words and explain their development. Section 3.1 demonstrates the benefits of using both the LAEME and CELEX corpora over using only one or the other. Type frequency proves nearly impossible to encode directly for ME, and difficult to a lesser extent for later periods, but it emerges in the present model indirectly, in the following manner. Types are encoded directly, by marking a verb with the features it shares with other verbs. Features that are shared by many verbs, i.e. the cases where the type frequency is high, are more salient than 172 features shared by only a few verbs. Chapter 3 investigated the effects of cue validity. It was argued that verbs that have preterites that begin with consonant clusters and end with <-ew> are more likely to remain strong than such verbs that do not begin with consonant clusters. This pattern was explained with reference both to type frequencies and to phonological similarities. ME words of the form CCew signalled the past tense better than words of the form Cew, because a greater proportion of the CCew words were strong preterites, relative to the number of nouns, adjectives, and present tense verbs. Moreover verbs that shared a /lew/ or /rew/ sequence were more similar, allowing them to reinforce each other to a greater degree than verbs that shared only /ew/. The presence of consonant clusters was adduced as an explanatory factor in survival because of the mismatch between LAEME frequencies and PDE outcome of <ew> preterites. Once-infrequent verbs such as throw and grow had strong preterites of sufficient salience that at the time when the lexemes became more frequent, they had not yet become weak. They thus contrast with a verb like walk, which had become weak by the time its frequency increased. The advantage of threw and grew was their CCew structure. Similarly, when once-frequent verbs became infrequent, their strong preterites had better chances of survival if they were of the shape CCew. Thus slew survived even when slay was replaced by kill, but sew was lost at approximately the same time as the frequency of sow declines in the written records. The role attributed to phonological similarity in the verbs throw, grow, slay stems from the idea that survival of very low-frequency strong preterites is inextricably tied up with their generation. This is especially clear in the case of slew, which was not the original preterite, but was generated often 173 enough to catch on. It survived partly because it matched an existing pattern, in contrast to sow. It survived also partly because speakers have instances of slew stored in their memories, in contrast to play, where they have only played stored. In Section 3.2 of this chapter, the explanatory power of the feature CCew is formally tested in a mathematical model, and its interactions with both ME and PDE frequencies are explored. Chapter 4 argued that vowel quantity played an important role in strong verb inflection. Long vowels were preferred over short, for both distributional and perceptual reasons. Long vowels arose elsewhere in verbal paradigms, and spread analogically into the parts of the paradigm where they did not arise phonologically. Moreover, vowels in strong verbs carry the grammatical information of tense inflection, and long vowels are more easily heard; thus they function better in strong preterites. The advantages of long vowels had two effects. One, verbs with the shortest vowels, those before certain consonant clusters, became weak. This includes verbs of originally low frequency, such as walk, that became more frequent; verbs of originally high frequency, such as warp, that became less frequent; verbs of consistently low frequency, such as melt; and verbs of consistently high frequency, such as help. In all cases, the strong preterite was not sufficiently salient to survive, either with the support of frequency or despite it. Two, verbs where several strong preterites competed in ME, were reduced in favor of variants with long vowels in Early Modern English (EMnE). This preference for long vowels was aided in many cases by type frequency, in that a variant with /O:/ was found in very many verbs of originally different inflection, e.g. drove, froze, broke, and wove. Section 3.4 of this chapter models the effects of quantity and its interaction 174 with other factors, in particular the large class of exceptions found among verbs conjugating like sing ∼ sang ∼ sung or sting ∼ stung. Chapter 5 extended the scope of the study to include verbs that were not originally strong, but that became irregular—either strong or no-change—as the result of phonological change. The no-change verbs were explored in particular detail. They arose from the addition of an allomorph of the regular weak preterite suffix, in cases where the verb stem ended in a dental stop. This dissertation identifies a series of events that led to the declining use of this allomorph with dental-final verbs. First, the OE system of productive prefixation was replaced with a system of phrasal verbs. The result was that most English verbs were monosyllabic. An influx of predominantly disyllabic French verbs were recognizably foreign-sounding, except in cases where the prefix was recognizable and the root monosyllabic, and they did not conform to native phonotactic preferences. The default suffix was added to almost all French loanwords ending in dentals. This created a distributional preference among dental-final verbs for the now more common default suffix, which had a buffer vowel between the dental of the stem and the dental of the preterite. The eventual loss of final vowels added a functional reason: presents and preterites became homophonous, as in cut ∼ cut, which did not permit the overt marking of past tense. The change of preferred suffix for dental-final verbs from OE to PDE was thus the result of both distributional and functional reasons. The identification of role of the French verbs and the close attention to the use of the competing suffixes among dental-final native words are new contributions of this dissertation. The results of Chapter 5 are not included in the model in Sections 2 and 3, but the section devoted to outlining prospects for further work on the subject discusses how these results might be added to a more complex 175 model. 6.2 The Model The most important factors that the present work hypothesizes to be relevant for the survival or loss of strong inflection are token frequency, type frequency, the CCew structure, and vowel quantity. In addition to these factors, I test a factor hypothesized by Welna (1991: 133) to be relevant: the presence of a final labial stop. In order to investigate the statistical significance and explanatory power of the described factors, a binary logistic regression model is used. The dependent variable is the inflectional outcome, and because the outcome is either strong or weak, a binary model is appropriate. They independent variables are frequency, CCew structure, vowel quantity, and the presence of a final bilabial stop. The logistic regression model operates by plotting the dependent variable, outcome, against the independent variables, creating an n-dimensional graph, where n is the number of independent variables. Best-fit lines are generated to explain the distribution of the strong and weak verbs in terms of the independent variables. The model’s goodness of fit is determined using the Akaike Information Criterion (AIC), which rewards success in accounting for the outcomes of verbs and penalizes the number of variables. A model that explained each and every verb accurately, but with a different account for each verb and no commonalities among different verbs, would be a poor model indeed. The lower the AIC figure, the better the model is (Akaike 1974). The logistic model was implemented using the statistics software program R, 176 using the glm() function53 . In order to make my work as transparent and as replicable as possible, this paper includes the code used at each step to generate the results. It is to be hoped that others will find this useful and will be able to build on it, adding new or more precise data, as well as further hypothesized independent variables. The greatest difficulty in seeking to set up a single model to test the hypothesized variables is that the study is diachronic, covering the span from OE to PDE. Many features of the data changed over time, and certain variables were relevant at certain periods and not at others. For the most part, collapsing the history of the strong verbs can be done without internal contradiction, but at times it will be necessary to run a test, make a change, and run the test with the change, then compare the two. Details of the adjustments necessary to represent a diachronic model are presented in sections 6.2.1 - 6.2.4. 6.2.1 Frequency The token frequency data have been gathered from LAEME, for Early Middle English (EME), and CELEX, for PDE. The data can be found in Chapter 2 and Appendix 2. In both cases, the number given represents all instances of verb forms in the corpus. Including both corpora—and the effects of each are tested separately—is a means of encoding the diachronic nature of the study. Though Hare and Elman (1995) found no substantive differences between the frequencies of OE and ME verbs, the difference between the EME and PDE frequencies of some verbs is great enough to warrant studying whether the model benefits from including both. Type frequency has proven almost impossible to encode directly, as noted in 177 section 6.1. There exists a standard division of OE strong verbs into seven classes, which, along with the sensible subdivisions used by Krygier, is entered into the model. One additional subdivision, the separation of the Class III verbs that later underwent Homorganic Cluster Lengthening, such as find, from the rest of the Class III verbs, such as sing, was deemed appropriate, because from EME on, these clearly belonged to different classes. Along similar lines, /a:u/ and /o:u/ merged in EME, and the verbs grōwan and crāwan, for example, became members of the same subclass. Thus, the separate subclasses VIIe and VIIf in Krygier’s classification are collapsed in this model to VIIef. A few individual verbs that changed classes are assigned to classes into which they shifted, Specifically, these verb reassignments are stick, which shifted from Class V to Class III, and fly, which shifted from Class II to Class VIIef, and draw and slay which shifted from Class VI to class VIIef. Such a treatment is not given to shit, which is treated as a weak verb originally belonging to Class I. The justification for this treatment is that we are interested in testing the frequency hypothesis. Verbs of lower frequency are expected to become weak, and shit did become weak. It later acquired a strong inflection because of its phonological shape, but that was a separate, much later development. Chapter 5, section 3 discusses the difficulties of determining the spoken frequency of shit, as well as the development of its strong preterite. The assignment of verbs to OE classes, otherwise nearly identical to that in Krygier (1994: 255-267), is presented in Table 6.1. A variable was created in R that holds the information on OE class membership for each verb. It should be tested not only for whether its effectiveness is statistically significant, but for whether its effects are overwhelmingly dominated by one class. For this purpose, I created a separate category for membership in 178 Table 6.1: Assignment of Verbs to OE Classes Class I Class II Class IIIa Class IIIb Class IIIc Class IIId Class IV Class V Class VI Class Class Class Class Class VIIa VIIb VIIc VIId VIIef rise write bide drive ride smite shrive shine bite glide gripe slide strike writhe stride shit whine flee choose lie (weak) fly shoot brook creep chew seethe brew sprout freeze reek sneeze (be)gin sing run win drink stink spring sting wring sink swim stecan climb cling sling swing shrink spin fling slink find bind wind grind help yield warp swallow mourn carve starve delve smart swell spurn fight burst thresh/thrash come bear break steal tear shear see give stand bid sit get eat wreak wash mete reap tread weave knead speak take draw slay swear (for)sake wake heave laugh shake wade ache shove step flay gnaw grave bake shave lade shed beat leap hew hold fall lie (strong) wax fold salt (all members underwent lexical loss before PDE) let know sleep sow blow flow grow mow throw low row crow glow Class IIIa, which is recognized by all scholars as a robust class that attracts new members. The effects of the overall class membership are tested for any additional explanatory power beyond that of membership in Class IIIa. Subsequent to OE, however, there exists no agreed-upon classification, and scholars have despaired of creating one, because of the great dialectal, chronological, and free variation of ME. Fisiak (1968: 106) classified ME strong verbs on the basis of the number of ablaut alternates in the paradigm. For example, cling ∼ clung is bi-alternate in PDE and sing ∼ sang ∼ sung is tri-alternate. Even that arrangement, though, is only a compromise, as even the number of ablaut alternates 179 was in flux. During ME, the number of principal parts in strong verb paradigms was in the process of being reduced, such that OE verbs had four principal parts and PDE verbs now have only three. Krygier (1994: 94) observes that not only does the number of ablaut alternates for a given verb vary over time, dialectal variation existed even in the number of alternates at a given date in ME, though he follows Fisiak’s classification faute de mieux. Krygier’s criticism is quite correct; moreover, Fisiak’s classification is not at all satisfactory for the needs of this model. The reduction of alternates is in large part an effect of type and token frequency, rather than a separate factor that influenced the outcome of strong verbs. This effect can be seen precisely in the case of the highly frequent sing vs. the less frequent cling. Chapter 3 studies in greater detail the relationship between the number of alternates and frequency, as well as phonological similarity. Classifications of PDE strong verbs have been made in PDE grammars such as Huddleston and Pullum (2002) and Quirk et al. (1985), but these do not include verbs formerly strong but now weak, and so are not useful for the purposes of this model. For this reason, no further attempts are made at directly encoding type frequency counts in the model. Type frequency effects are felt indirectly in that a hypothesized variable has more explanatory power the more verbs it explains. So, for example, Chapter 3 argued that it is not only the inherent feature of the CCew structure, but the fact that it is shared by several verbs, that makes it a salient characteristic of strong preterites. 180 6.2.2 CCew The CCew structure is the simplest to encode in the model. All verbs beginning with consonant clusters in ME that inherited strong preterites in <-ew>, namely crow, grow, throw, flow, blow, glow, and know, as well as those three verbs, fly, slay, and draw, where the <-ew> preterite spread analogically and took over, are so marked. Flay and gnaw are not included, because the <-ew> preterite was never the dominant one. Data on the CCew verbs can be found in Chapter 3. 6.2.3 Vowel Quantity In Chapter 4, the effects of vowel quantity on strong inflection were seen to have been operative in ME. Long vowels spread to parts of the paradigm where they did not arise phonologically, and verbs without long vowels in the preterite were more likely to become weak. Since that time, many of the long vowels have become short. For example, all Class VI verbs originally had /o:/ in the preterite, which the Great Vowel Shift raised to /u:/. In the case of shook, took, forsook, and stood, a later shortening took place, resulting in PDE /U/. It is no longer possible to claim that strong verb preterites prefer long vowels. Rather, it is the case that some paradigms contain artifacts of a former preference for long vowels, and the absence of strong preterites in some verbs, such as help, is due in part to their lack of long vowels. For this reason, it is necessary to mark verbs as possessing long vowels based on their ME forms, just as verbs were marked for initial consonant clusters based on their ME forms, leading to the inclusion of know and the exclusion of (h)low. With the dates having been thus narrowed, there still remain decisions to be made about the vowel quantity of various verbs. 181 Though there is orthographic evidence from spellings such as <soong> that verbs ending in <ng> underwent Homorganic Cluster Lengthening at least sporadically, the lengthening was undone in cases where it did take place. Such verbs are treated in Chapter 4 as a major class of exceptions to the general preference for long vowels. These exceptions are permitted by reason of their type frequency and phonological similarity, and they are marked as not possessing long vowels in the model. Verbs where long vowels spread to the preterite from the participle are so marked, because the ability to spread the vowel is, according to my hypothesis, a contributing factor to the survival of their strong inflection. Thus, Class IV and V verbs are marked for long vowels, as are Class III verbs where Homorganic Cluster Lengthening applied consistently in the present and participle, as in find. Verbs ending in diphthongs are marked as possessing long vowels. The assignment of verbs to vowel quantity is laid out in Table 6.2. Table 6.2: Vowel Quantity Long Short ache, bake, bear, beat, bide, bind, bite, blow, break, brew, brook, chew, choose, come, creep, crow, draw, drive, eat, find, flay, flow, fly, fold, freeze, give, glide, glow, gnaw, grave, grind, gripe, grow, heave, hold, knead, know, lade, laugh, leap, lie (strong), lie (weak), low, mete, mow, reap, reek, ride, rise, row, sake, seethe, shake, shave, shear, shine, shoot, shove, shrive, slay, slide, smite, sneeze, sow, speak, sprout, stand, steal, step, stride, swear, take, tear, throw, tread,wade, wake, weave, whine, wind, wreak, writhe, yield begin, bid, burst, carve, climb, cling, delve, drink, fall, fight, flee, fling, get, help, hew, hold, let, mourn, run, salt, see, shed, shit, shrink, sing, sink, sit, sleep, sling, slink, smart, sping, spring, spurn, starve, stick, sting, stink, strike, swallow, swell, swim, swing, warp, wash, wax, win, wring 182 6.2.4 Labial Stop Welna (1991: 133) observes that all the OE verbs ending in labial stops are now weak, listing gripe, reap, creep, sup, climb54 , help, warp, yelp, shape, step, leap, sleep, sweep, and weep. He writes, “Such consistent behaviour of the above 14 verbs, with no examples of the contrary development, testifies to a special impact of labials in English, but not in other Germanic languages.” It is unclear, however, whether the absence of PDE strong verbs ending in labial stops represents anything more than a coincidence. Chapter 4 attributes the weak outcome of help, warp, and yelp to the phonetically short vowel of the strong preterite, which led to high confusability with the weak preterite. Krygier omits sleep from the strong verbs on the grounds that it was already predominantly weak in OE. Fertig explains sup with the fact that strong sup coalesced with its weak counterparts OE suppan and supian, and he explains shape as a verb that was reanalyzed as a denominal and therefore weak. Fertig also gives yelp as a possible example of reanalysis as a denominal. Omitting these verbs leaves gripe, reap, creep, climb, step, leap, sweep, and weep. Because I can neither offer a principled explanation for why the labial should have been relevant, nor reject it outright, I mark gripe, reap, creep, climb, step, leap, sweep, weep, help, warp, and yelp as possessing the feature “labial” and test the explanatory power of this variable in the model. Because climb lost its final labial stop circa 1300 (Jordan-Crook 1974: 190)55 , it is necessary to encode this by first testing the model with climb marked as labial and then test it with climb not marked as labial. For the same reason, it is necessary to mark climb first as belonging to Class IIIa, with verbs like cling, and then to have it change class. It is not entirely clear where to put it. It underwent HCL in the present, but does 183 not otherwise inflect like find in PDE. After the verb climb had become weak, Elizabethan archaists created an unetymological past tense /klo:m/, so I assign it to Class I, with verbs like gripe, when it is not in Class III. If most of the explanatory power of the feature “labial” comes from its ability to explain climb, then changing climb will make a significant difference to the model; otherwise, no difference will be noticed. 6.3 Results A data frame in R was created to organize the data in the form of a matrix, with each row containing the information for an individual verb, and each column representing a variable. The data frame was named verbs. The column containing the PDE inflectional outcome was coded using S or W for each verb to represent strong or weak, and the column was labelled verbs$Outcome. Two columns were created with the token frequency data, one from the LAEME corpus and one from CELEX, and these were labelled respectively verbs$LAEME and verbs$CELEX. The column for vowel quantity records a 1 for a long vowel and a 0 for a short vowel, and was labelled verbs$Quantity. The column containing the features for final labial stop and CCew preterite structure record a 1 for verbs with the feature and 0 for verbs without the feature. They are labelled respectively verbs$Labial and verbs$CCew. Likewise, membership in Class IIIa is indicated with a 0 or 1, and a column heading verbs$ClassIIIa. The column containing class membership, labelled verbs$Class, contains the name of each class, “I”, “II”, etc., and these are listed as strings rather than numbers, so that the model does not treat them as ordered in any way. In R, the list of strings is called a factor and is opposed to a 184 vector, which is a list of numerals. The usual method for testing models is to include all the independent variables as the baseline model, remove variables individually, and see if the model improves or worsens as a result of losing a variable. R operates using input from the command-line, so the code used to obtain the results is included for maximum reproducibility. The basic command is given in (1), and the permutations on the variables are studied in 3.1-3.4. (1) Code for baseline model summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$CCew + verbs$Class + verbs$ClassIIIa, family = ‘binomial’)) This means that a generalized linear model creates best-fit lines for the outcome of the verbs, given the predictive variables, which are separated by a + sign. Upon carrying out this command, R displays a summary of the results. The code in (1) obtains for the AIC, which is the figure in which we are interested, a value of 89.159. To this figure will be compared the AIC of all other variants of the model. 6.3.1 Frequency The first test to be carried out, with the code given in (1), is to ascertain whether token frequency has predictive power in the model. The expected answer is that it should very much have predictive power. The second test, with the code given in (2) and (3), investigates whether the LAEME corpus or the CELEX corpus has more predictive power than the other, and the third investigates whether we gain anything from having both in the model, or whether including both is redundant. 185 Table 6.3 compares the AIC values for each variant of the model. (1) No frequency summary(glm(verbs$Outcome ~ verbs$Quantity + verbs$Labial + verbs$CCew + verbs$Class + verbs$ClassIIIa, family = ‘binomial’)) (2) LAEME only summary(glm(verbs$Outcome ~ verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$CCew + verbs$Class + verbs$ClassIIIa, family = ‘binomial’)) (3) CELEX only summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$Quantity + verbs$Labial + verbs$CCew + verbs$Class + verbs$ClassIIIa, family = ‘binomial’)) Table 6.3: Frequency Effects Akaike Information Criteron (AIC) No frequency 141.43 LAEME only 100.43 CELEX only 96 LAEME and CELEX (baseline model) 89.16 The difference between a model with token frequency and a model without is immediately clear, and it is a drastic difference: 89 vs. 141. These figures provide yet another confirmation of the well-understood correlation between high token frequency and conservative inflection. Two conclusions are new, however. First, the AIC values show that using the frequency counts from CELEX provides a small but significant improvement over those from LAEME. Second, they show that the frequency effects of LAEME are not all encompassed in CELEX, and that 186 LAEME makes enough of a contribution to be worth including in the model. This is an argument for using historical corpora in studies of English verbs, something that it is to be hoped other studies will take more advantage of, especially now that more and more corpora are being prepared and made available in a searchable format. Another test, using a support vector machine, indicates that the difference between the predictive power of CELEX and LAEME data in that method is not great enough to be significant. A support vector machine is a method of classification and operates by seeking to maximize the number of correct classifications. In this case, it maximizes the number of correct weak and correct strong outcomes. We can use this to compare the ability of CELEX and LAEME frequency data to predict correctly the outcomes of verbs. The code for carrying out these tests in R, given that LAEME is column 3 in the matrix and CELEX column 4, is provided in 1 and 2. (1) Support vector machine, using LAEME summary(svm(verbs[,3], verbs$Outcome, cross = 10)) (2) Support vector machine, using CELEX summary(svm(verbs[,4], verbs$Outcome, cross = 10)) The test is cross-validated ten times, which means that ten times the model chooses a random data point to leave out of the sample and attempts to predict it using the remainder of the data. The numbers are given in Table 6.4. A statistical significance test comparing the two, such as prop.test() in R, yields a p-value of 1, which shows that the difference between 91 and 92 correct predictions cannot be distinguished in a statistically significant way from results obtained from chance. The code for the calculations is given in (1). 187 Table 6.4: Classifications by Frequency LAEME CELEX % Correct classifications # Correct classifications 68.94% 91 69.69% 92 (1)Comparison of LAEME and CELEX Performance prop.test(c(91, 92), c(132, 132)) Thus, in a generalized linear model, CELEX has a slight advantage, but LAEME is a beneficial addition to the model. When using a support vector machine to maximize classification of the data, CELEX and LAEME are equally effective. Which model to use depends on the goal of the research being carried out: to create an explanatory model for the system as a whole, or to find the criterion that will do the best job of dividing verbs into strong and weak categories. 6.3.2 CCew It has long gone unnoticed that while the verbs whose preterites end in <-ew> mostly have high frequency in PDE and those that lost <-ew> preterites have low frequency in PDE, the relative frequencies in OE and EME are quite different. Nor can it be assumed a priori that, given a change in frequency over time, the outcome will always reflect the most recent frequency. For a counterexample, (for)sake was highly frequent in LAEME, being ranked at 38 out of 132, and is of low frequency in CELEX, being ranked at 119 out of 132. Yet its PDE preterite forsook is more in accord with its EME frequency than its PDE frequency. For this reason, Chapter 3 introduces an additional explanatory factor to ac- 188 count for verbs such as threw and grew, which did not become weak before their frequency increased, and verbs like mow and sow, which did become weak when their frequency decreased. This factor was the presence of an initial consonant cluster. The hypothesis predicted that the model will find the variable CCew to be important when PDE frequencies are not included. It is not immediately clear whether this will be the case when PDE frequencies are included. The code for these tests are given in (1) – (3). (1) tests the model with all the variables being used, excluding CCew. (2) tests the model when the CELEX frequencies are omitted but CCew is left in. (3) tests the model when both the CELEX frequencies and CCew are omitted. The results are presented in Table 6.5. (1) No CCew summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$Class + verbs$ClassIIIa, family = ‘binomial’)) (2) No CELEX summary(glm(verbs$Outcome ~ verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$Class + verbs$CCew + verbs$ClassIIIa, family = ‘binomial’)) (3) No CELEX or CCew summary(glm(verbs$Outcome ~ verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$Class + verbs$ClassIIIa, family = ‘binomial’)) When the PDE frequencies from CELEX are included, CCew contributes a barely perceptible improvement in the model, as the AIC values 89.16 vs 89.98 show. It is probably the case that slew and crew, both of which are infrequent, 189 Table 6.5: CCew baseline model Without CCew Without CCew or CELEX With CCew, without CELEX Akaike Information Criteron (AIC) 89.16 89.98 105.75 100.43 persist in part because of their CCew structure. The difference in the AIC values, even though slight, is all the more significant in that the model is penalized for every additional variable. Even with this penalty, and with LAEME and CELEX frequencies, CCew adds explanatory power, even if only to a low degree. When the CELEX frequencies are omitted from the model, to approximate an earlier stage of the language, CCew improves the model even more noticeably, from an AIC of 105.75 down to 100.43. The importance of the consonant cluster in these verbs is in accord with the fact that all new members of the class in ME also began with consonant clusters, indicating that the cluster was an important feature for membership. It is clear that know, which lost its cluster at approximately the end of ME (Minkova 2003), remains strong because of its very high frequency. To support the idea that CCew is diminishing in its power to offset low frequency and preserve strong inflection, we find that crew is vanishing among English speakers in favor of crowed. Slew, which is also partly explained by its high frequency in earlier periods before it was replaced by killed, is beginning the process as well. Merriam Webster records slew as the default preterite, but notes that slayed is used as well, especially in the sense “to delight or amuse immensely.” 190 6.3.3 Class vs. Class3a As has been noted, class membership is another feature that varies so much and changes so quickly that it is difficult to represent in a single model. The only tests here are whether OE class membership, which is the easiest to define, contributes anything to the model, and whether it contributes anything in addition to membership in Class IIIa, the sing ∼ sang ∼ sung verbs. The code is given in (1) – (3), with (1) having no class membership at all, (2) having membership in ClassIIIa, and (3) containing the general assignment of each verb to an OE class. The results are summarized in Table 6.6. (1) No class membership summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$CCew, family = ‘binomial’)) (2) Class IIIa membership summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$ClassIIIa + verbs$CCew, family = ‘binomial’)) (3) Overall class membership summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$Class + verbs\$CCew, family = ‘binomial’)) From the great difference between 125.37 and 89.16 in Table 6.6, it can be seen that class membership does play a role. This is to be expected. What was not apparent before the fact was that OE class membership, as a whole, is a slightly poorer predictor of outcome than the simple prediction that Class IIIa verbs will 191 Table 6.6: Class Membership No class membership Class only Class IIIa only Class and Class IIIa (baseline model) Akaike Information Criteron (AIC) 125.37 87.16 86.18 89.16 be strong. This is not to suggest that other classes and subclasses do not behave consistently. In fact, small increments of improvement in the AIC are obtained by adding Class IIIb—which has also consistently strong outcomes in bind, find, grind, wind, and could have been left united with Class IIIa, despite no longer inflecting alike—Class I, Class IV, and Class V. The effect of adding these classes to the model is shown in Table 6.7. (1) Individual Class Membership summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$CCew + verbs$Class3a + verbs$Class3b + verbs$Class1 + verbs$Class4 + verbs$Class5, family = ‘binomial’)) Table 6.7: Individual Class Membership No class membership Class only Class IIIa only Classes I, IIIa, IIIb, IV, V Akaike Information Criteron (AIC) 125.37 87.16 86.18 78.81 Outside of classes I, IIIa, IIIb, IV, and V, class membership does not correlate with inflectional outcome such that the model is improved. One may observe 192 that Classes I, IV, and V came to share the /O:/ preterites that speakers favored wherever possible. The increased survival rate of these verbs suggests that /O:/ was not only favored in selection from among ablaut variants, but also may have favored verbs to remain strong rather than become weak. Against this hypothesis, however, it should be noted that Class II, which also shares the /O:/, is not at all conservative. Of 13 members, only choose and freeze, retained strong inflection. See Chapter 2 for further detail on the behavior of individual classes. 6.3.4 Quantity In Chapter 4, it was hypothesized that long vowels were generated in place of short wherever possible in strong preterites, that short vowels were not generated in place of long vowels except before dentals, and that where no long vowels were possible, the strong preterite was more likely to disappear in favor of the weak preterite, except in Class IIIa, the sing ∼ sang ∼ sung verbs. Using the model, (1) tests the effects of removing vowel quantity from the model and Table 6.8 compares the results to the baseline model. (1) Vowel Quantity summary(glm(verbs\$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$Class I + verbs$ClassIIIa + verbs$ClassIV + verbs$ClassV, family = ‘binomial’)) Table 6.8: Vowel Quantity baseline model without Quantity Akaike Information Criteron (AIC) 78.81 80.42 193 Table 6.8 shows that the model worsens, from an AIC of 78.81 to 80.42, when quantity is removed, suggesting that quantity played a role in the survival or loss of strong inflection. 6.3.5 Labial-final Stems To test Welna’s hypothesis that the verbs with a final labial stop are more likely to become weak than other verbs, the baseline model is compared with the model when the variable verbs$Labial is removed. Then, because climb had lost its labial stop by about 1300 (Jordan-Crook 1974: 190), the baseline model and the model without verbs$Labial are revised so as to remove the feature labial is removed from climb and its class membership is moved from IIIa to I. The code for these tests is given in (1)-(4), and the AIC values are presented in Table 6.9. (1) Baseline model (with ‘climb’ labial) summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$CRew + verbs$Class3a + verbs$Class3b + verbs$Class1 + verbs$Class4 + verbs$Class5, family = ‘binomial’)) (2) Baseline minus labial (with ‘climb’ labial) summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$CRew + verbs$Class3a + verbs$Class3b + verbs$Class1 + verbs$Class4 + verbs$Class5, family = ‘binomial’)) (3) Baseline model without ‘climb’ summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$Labial + verbs$CRew + verbs$Class3a + verbs$Class3b + verbs$Class1 + verbs$Class4 + verbs$Class5, family = ‘binomial’)) (4) Baseline minus labial without ‘climb’ 194 summary(glm(verbs$Outcome ~ verbs$CELEX + verbs$LAEME + verbs$Quantity + verbs$CRew + verbs$Class3a + verbs$Class3b + verbs$Class1 + verbs$Class4 + verbs$Class5, family = ‘binomial’)) Table 6.9: Climb baseline model (with climb) without labial (with climb) baseline model (without climb) without labial (without climb) Akaike Information Criteron (AIC) 78.81 98.07 79.56 89.68 The difference between the baseline models and the models without the variable Labial in Table 9 suggests that the presence of a final labial stop correlated with a tendency to become weak. The great difference between the models with and without climb marked as labial implies that the labial stop would make a good explanatory factor for the weak outcome of climb, if it were not for the chronology. Lacking a functional explanation for why the final labial should have been relevant, I assume by default that distributional factors were at work. Should a plausible functional explanation be proposed, the data and the results of this model would have to be reanalyzed. Because climb both lost its strong preterite and its labial stop before any of the other verbs ending in a labial stop became weak, it is implausible that climb became weak as a result of pressure from other verbs. No other strong verbs end in /aim/. However, verbs such as sweep, weep, creep, and leap may have been drawn into the weak category by analogy with verbs such as sleep and keep. If several verbs ending in /p/ came to have weak /ept/ preterites by analogy with existing /ept/ preterites, in addition to the weakening of help, warp, and 195 yelp based on their short vowel, an island of reliability may have arisen in the grammar. The island of reliability would make verbs such as step more likely to lose their strong inflection. 6.4 Conclusions The model presented in this chapter provides additional confirmation for the role of vowel quantity in the survival of strong inflection, and for the role of the initial consonant cluster in <-ew> preterites at an earlier stage in the language. OE class membership has predictive power for classes I, IIIa, IIIb, IV, and V, but the overall effect of attempting to use class membership on the model is less powerful than simply classifying verbs according to whether or not they belong to the sing ∼ sang ∼ sung family. There is evidence that the feature of final labial stop has predictive power above and beyond the other factors and is worth investigating further. 6.5 Further Research What has been presented in this dissertation is an exploration of factors that were relevant to the history of the verbs that were originally strong in OE. Yet it is obvious that these strong verbs did not exist in a vacuum in the grammar; rather, their behavior is inextricable from interactions with the weak verbs. Studying the originally weak verbs would thus be appropriate for further work on the subject. One obstacle of studying the weak verbs is that they outnumbered the strong verbs, at least in OE and EME, by a ratio of 3:1, and this ratio increased over time. Doing a comprehensive study of each verb is thus less practical. For this 196 reason, many of the resources that exist for strong verbs, including such simple things as a list of each OE strong verb, do not have counterparts for the weak verbs. It would thus be useful to go through Bosworth and Toller’s OE dictionary and compile a list of all the weak verbs. It would then be practical to take a random sampling and conduct research on that, instead of on the entire set. One important factor in the history of strong verbs that scholars agree on (Welna; Krygier; Fertig) is that nearly every OE strong verb had a corresponding derived weak counterpart. In many cases, the strong and weak counterparts fell together, producing a weak verb with the semantics of both the original verbs, while in other cases they did not. At present we do not have an explanation for which fell together and which did not (Krygier 1994: 20-21). The place to begin would be with relative frequency counts of the strong verbs vis-à-vis their counterparts. The corpora exist, as now do the frequency counts for the strong verbs, so gathering the frequencies for the weak verbs is the next straightforward step. When the extent of the effects of frequency are identified, semantic similarity should be considered. Phonological similarity exists among unrelated verbs as well. Albright and Hayes (2003) have shown that the phonological structure of weak verbs is analyzed in the same way as with strong verbs. The fact that verbs with certain phonological structures are more reliably weak than verbs with other structures is recorded in speakers’ grammars and taken into account when generating the past tenses of new verbs. For example, all English verbs that end in voiceless fricatives are weak, so a new verb ending in a voiceless fricative is more likely to be weak than a verb ending in a voiced fricative. Albright and Hayes give the name “islands of reliability” to these phonological structures for which inflection can be predicted 197 with a greater than usual confidence. For this reason, a full study of the English verb system would take into account structures that are shared by both strong and weak verbs. The structure CCew, for example, is a common strong preterite, but there are many weak verbs, such as slow, that could participate, but don’t. The interaction of weak verbs such as slow with strong verbs such as grow should be investigated. The effects of changes of token frequency over time have been investigated, and they have been found to be restricted but recognizable. For type frequency, the relative number of weak vs. strong verbs was touched upon in Chapter 5. There, it was noted that the “shift”, or, more accurately, the increase in instability, is often attributed to a rise in the number of weak verbs, due to borrowing from French. The calculations in Chapter 5 do not support this hypothesis. However, since that time, there has been an influx of borrowings from French, Latin, and Greek, such that the current ratio of strong to weak verbs is even lower than the 3:1 ratio of OE and EME. Using a list of 4595 past tense forms from CELEX, which counts participles and preterites separately when these are not homophonous, a search for forms ending in <-ed> yields 4234 hits. The remaining 361 forms are strong or suppletive, or add the weak suffix but do so irregularly, such as said, bought, kept, burnt. The proportion of perfectly regular types, then, is at least 92%. Most of these items are low-frequency verbs belonging to an educated register, and it should be investigated whether this increased imbalance in weak/strong inflection has created additional pressure for strong verbs to become weak. For a full study of the English verb system, the formal model should be made more complex. The present model, for the sake of simplification, considers only strong verbs as input to the system, and as output whether they become weak or 198 remain strong. A strong verb that changed class, such as fly, which acquired the past tense flew by analogy, is treated no differently than a strong verb that retains its inherited preterite, such as drive. Weak verbs also either remained weak or entered various strong classes, and the existence of two weak suffixes, evident in wanted and put, complicates matters even further. In order to contend with this level of complexity, the model should employ multilinear logistic regression. Unlike binary logistic regression, which allows only two outcomes, in our case strong or weak, multilinear regression would permit each strong class and each of the weak suffixes to be a separate possible outcome. The analysis would benefit from an examination of more measures of goodnessof-fit beyond the AIC value, such as the p-values for the coefficients of the variables. Testing for interactions of variables could be done in a more rigorous way by specifically encoding variable interaction in the model rather than by impressionistically noting when the AIC value seems to indicate that the significance of one variable is dependent on another.56 In addition, the goal of the model was to test the explanatory power of the hypothesized factors such as vowel quantity. A more thorough approach might take the form of a learning model, with verb preterites generated over multiple generations and the possibility of making changes to the data. This approach would be in better accord with the diachronic nature of the history of English verbs. Notes 1 I am grateful to Donka Minkova for sharing with me a pre-publication draft of the grammar. 2 See especially Bybee (2001) and the collected articles in Bybee (2007). 199 3 See Zuraw (2003) for discussion. 4 To tell untruths. Lie meaning ‘to assume a recumbent position’ was a Class V verb, licgan. 5 LAEME does not distinguish between brinnan and bærnan, so this number includes counts for both. 6 In PDE only in the prefixed form engrave. 7 Rare in PDE. 8 Here I include both forsake and any other forms, prefixed or unprefixed, belonging to this root. Already in LAEME forsake predominates 150 hits to 3. 9 10 SumT 1704 “But natheles, for fere yet he quook” Though smite did not decline in frequency steadily after OE, but rather enjoyed a period of increase before decreasing, it is employed because I found no examples of steady decrease. The corpora prohibited the investigation of many verbs due to pernicious homophony with other forms, so this absence of any verbs with a steady decline should not be taken as a definitive statement about the entire system, but rather as an area meriting further research. 11 As an illustration of the fact that a word-final dental stop is prone to be interpreted as the preterite morpheme, consider the word linguished, which arose from a misinterpretation of the word linguist as a past participle of a back-formed linguish (Oxford English Dictionary (OED)). 12 This date is especially difficult to obtain with confidence, because the spelling <o> in the preterite is ambiguous. It may represent the rounded allomorph of /a/ that occurred before a nasal in the West Midlands, in other words the inherited preterite. Alternatively, it may represent a common ME orthography for /u/, in other words the grade leveled from the past participle. Only the orthography <ung> can therefore be relied upon. What this means is the pronunciation /2ng/ may have been in place earlier than the dates in the following tables indicate, but have been obscured by the orthography. 13 Unlike Bybee and Moder, I do not include come ∼ came ∼ come, due to the difference of the PDE vowel in the preterite singular. 14 MED citation: c1540(?a1400) Destr.Troy (Htrn 388)8843: Alphenor the fuerse flung he to dethe 15 For details on this history of hang and its various dialectal forms, see the OED entry. 16 At least in some dialects and meanings. 200 17 E.g the Cursor Mundi, a northern text, rhymes draw and know in “þair watur at þis well to drau, / þar sal i mi womman knau” (3277-78). 18 Earlier in other dialects. Watson (1946) argues that in Northumbrian, a merger of eo and ea had taken place already in OE. 19 Stockwell and Minkova (1992: 199) list guild, build, meld, and seldom as exceptions that survive in PDE. Of those, guild and build have orthographic indications of lengthening earlier in their history, and seldom does not meet their criteria for the environment that triggered lengthening; namely, the -l- and -d- are heterosyllabic. 20 I use sprang for the example to exclude the suggestion that competition with the noun song might have been the reason sang was chosen as the preterite. This argument would not apply to 13 of the 15 verbs in question. Only song and strong (past tense of string) would have been homophonous with a noun or adjective. 21 (c1387-95) Chaucer CT.Prol.(Manly-Rickert) A.672: “Ful loude he soong [vr. songe], ‘com hider loue to me.’ ” 22 This leveling was part of a more general ME reduction of inflection across noun and verb paradigms, a tendency that can be described but has not fully been accounted for. Language contact with French and Scandinavian may have played a role, but simultaneous phonological and morphological reduction form a notorious chicken-and-egg dilemma. 23 The Class I verbs used by Long, whose methodology and principles of inclusion differ from the present work’s, are bide, bite, chide, cleave, drive, flite, glide, ride, rise, rive, shine, shrive, slide, smite, stride, strike, strive, sty, thrive, wite, write, writhe. 24 See Long (1944: 38) for textual citations of fifteenth-century occurrences. 25 Peter Langtoft’s Chronicle p. 14 lines 11-12: He toke leue at Charles, & com tille þis lond, / Among his riche kynde gode frendes he fond. 26 Northern only. 27 Northern only. 28 One possible example. 29 Different dialects, of course, made different selections from among the various possibilities. I am interested here primarily in the history of the standard PDE dialect. 30 “I never writ, nor no man ever loved” (Shakes. Sonnet 116). 201 31 Later diphthongized, of course, by the Great Vowel Shift. 32 Verbs with idential presents and preterites do exist in English, of course, all ending in dentals, such as put. 33 Thanks are due David Fertig for helping develop the details of this account in an exchange of personal communications. 34 A dialectal variant of <d/tode>. 35 The current form lend is the result of backformation from the preterite lende. 36 The mechanisms by which these dispreferred sequences are avoided continue to be debated, though the fact of avoidance has been well-established since at least Brugmann (1909: 1975). In the morphological camp, hypotheses such as affix-checking (Menn and MacWhinney 1984) and vacuous rule application (Stemberger 1981) have been proposed. In the phonological camp, the OCP is used to explain all “morphological” haplology, which is taken to be not morphological at all (Plag 1998). The reasons behind the limited production of the syllabic morphemes –es and –ed by very young English-speaking children are also debated. Berko (1958) concludes that children acquire the syllabic plural and preterite allomorphs -ed and -es later than the other allomorphs. Bybee and Slobin (1982) conclude instead that children begin with a schematic analysis that looks only at the final shape of the preterite, and gradually start to extend the suffixation process and restrict the schematic analysis. Because the preschoolers they tested favored verbs without an overt suffix, and the third-graders and adults favored verbs with the overt suffix, they argue that this has implications for language change. The locus of language change is commonly believed to be in the speech of small children, and this is often the case. In these verbs, however, children “change their mind” as they grow older, and they produce a great number of overtly suffixed forms. As a result, the overtly suffixed forms are the default in the language, and Bybee and Slobin predict that the direction of inflectional change will be toward more overtly suffixed forms. Wedded and wetted are predicted to win out over wed and wet, if this trend continues. 37 Considering only morphology here, and not phonological changes such as failure to reproduce the vowel precisely, failure to pronounce the initial cluster, glottalization of the final /t/, etc. 38 “Accoutred as I was, I plunged in.” (Julius Caesar, 1.2.113) 39 The two forms have now been separated according to meaning and pronunciation, with putt 202 and putted limited to golf in the standard dialect. See the Oxford English Dictionary (OED s.v. put) for the dialectal distribution. 40 And Latin. It is at times impossible to determine which is the immediate source of a word, and for our purposes it does not matter, as French and Latin loanwords are alike in being predominantly di- and polysyllabic. 41 cost, grant, hurt, part ‘depart’, quit, rest, roast, void 42 anoint, circumcide, command, consecrate, convict, dispute, profit, provide, record, repent, translate, visit 43 The forms <wante> and <want> are marked by the MED (s.v. wanten) as possible scribal errors. If so, the average for this column should be even lower. 44 “Beat, the preterimperfect tense, is frequently pronounced in Ireland like bet (a wager), and if utility were the only object of language, this would certainly be the preferable pronunciation, as nothing tends more to obscurity than words which have no different forms for their present and past times (italics DM); but fashion in this, as in many other cases, triumphs over use and propriety; and bet, for the past time and participle of beat, must be religiously avoided.” Walker (1791). Discussed in Minkova (2009: 335). 45 Beat might have been expected to shorten in the present, like sweat and other cases of /E:/ before a dental, and the preterite should have followed suit, resulting in a no-change verb with a short vowel followed by a dental. Yet it did not shorten. This I am at a loss to explain and must attribute to random chance. All instances of the preterite in the Linguistic Atlas of Early Middle English (LAEME) seem to have a short vowel. The shortening of let, on the other hand, is presented by the OED as not yet satisfactorily explained. I adduce sweat, from swǣtan, as a parallel for the shortening of the vowel in the present tense lǣtan. The shortening of the vowel in the preterite lēt may derive from the product-oriented schema, where short vowels are preferred before dentals. Of all the no-change, only beat is long, and Walker shows that it was shortened at least in Ireland. The fact that beat was not shortened in the standard dialect is more surprising than the fact that let was shortened. Confusion with the weak verb lettan ’hinder’ may also have been a factor; for a parallel, see the confusion between cleave ’adhere’ and cleave ’split’ discussed in Chapter 2. 46 “I say, isn’t bread ‘riz’ enough when it runs over the pans?” (Little Women, Chapter 11) 203 47 Including 7 that have since suffered lexical loss. 48 Further breakdown: 5 with strong weak variation, e.g. shear, crow; 8 with weak past and both weak and strong participles, e.g. sow, hew; 6 with vowel change and dental suffix, e.g. creep, sleep; 1 (burnt) with irregular suffix –t and no vowel change; 3 synchronically strong: read, slide, shoot; 5 no-change e.g. let, shed. 49 Including 17 that have since suffered lexical loss. 50 “A little less than three quarters” (Quirk and Wrenn 1957: 40). 51 I thank David Fertig for bringing this passage and its relevance to the ME strong verbs to my attention. 52 I thank David Diez, doctoral candidate and then graduate of the UCLA Department of Statistics while he worked with me, for giving me directions for carrying out the logistic analysis. Ingo Plag offered a number of further suggestions for which I am grateful, though I unfortunately did not receive them until shortly before filing the dissertation and was able only to incorporate them into the dicussion of further work on more sophisticated models. 53 See Baayen (2008) on logistic models, their implementation in R, and their use in linguistics. 54 The status of the labial stop in climb is a matter of discussion in Section 3.5 55 Note also the OE form climman, indicating that the stop was no longer always present as early as OE. 56 I thank Ingo Plag for pointing out that parsimony is not of concern in a regression model and that it is preferable to include even variables previously determined to be insignificant when testing for the significance of one given variable. 204
