A pronounmust have an antecedent(referent)to which it refers. 2. The pronounmustreferclearlyto the antecedent. 3. The pronounandantecedenlmusL agree. 4. The pronounmust havethe appropriate case. PRONOUN MUST HAVE AN ANTECEDENT A pronounis usedas a substitutefor a noun. Thc nounit replacesis calledits antecedent or its referent.With tire e x c e p t i o no f c c r t a i ni d i o m ss u c ha s " 1 ti s r a i n i n g , "a p r o n o u nt h a td o e sn o t h a v ea n a n t e c e d e ni st u s e di n c o r r e c t l y .

PRONOUNS MUST HAVE ANTECEDENTS Except for a few idiomatic expressions-lt is gettitrg late-all pronouns must have an antecedent.An antecedent must be a noun, not a thought or phrase. When inserting antecedents, substitutethe proposedantecedentfor the pronounand verify that the sentenceis corTect. 2. ANTECEDENTS MUST BE CLEAR Secondly,the antecedent of a pronounmustbe clearfrom the structureof the sentence.Considertheseexamples: Examples: Edward'sfatherdied beforehe reachedhis 20th birthday,so fte neverfinishedhis education. In 1980,the UniversityCouncilvotedto rescindprovision3 which madeit easieribr somestudents to graduate. In the hrst example,it is not clear whetherthe fatherdied beforehe reachedthe ageof 20 or beforeEdwardreachcdthe ageof 20. Furthermore,it is not entirelyclearwhoseeducationremainedunfinished. Similarly,in the secondexample,the antecedent of which is not made clear. Whichmay refer to the provisionor it may refer to antecedents of the pronouns. WATCH FOR UNCLBAR ANTECEDENTS Theantecedent of a pronoun mustbeclearlyidentified by thestructure of thesentence. 3. PRONOUN-ANTECEDENT AGREEMENT The third rule for pronounusageis that the pronounmustagreewith its antecedent.Considerthe following example: , E x a m p l e : H i s t o r i c a l l y , t h e d e a n oafc o l l e g e w a s a l s o a p r o f e s s o r , b u t t o dt h ae y y a r eu s u a l l y p r o f e s s i o n a l administrators.

WATCH FOR PRONOUN-ANTECEDENT AGREEMENT AND SHIFTING SUBJECT If the antecedent is plural, the is singular,the pronounmust be singular;if the antecedent pronounmust be plural.

The following examplesillustratethe conect useof pronouncase: ExampLes: Subjective: / thoughtlie would like the gift we bought. Objective: The choicefor the promotionis betweenBob and me. (The object pronounnre follows the prepositionbetween.) Possessive:Do you mind riryusingyour computer? (The possessivepronounrny precedesthe gerundusing.) Interrogative: Whosediny dishesare these?

WATCH FOR ILLOGICAL COMPARISONS Be alertfor sentences which attemptto makean illogicalcomparisonbetween wo dissimilar items. B. VERB TENSE A secondfairly common problemof logic-alexpressionis poor choice of verb tense. WATCH FOR INCONSISTENTVERB TENSES Makesurethatverbtenses properlyreflecttheorderanddurationof actiondescribed. C-14 ACT BaSTCGRAMMAR REVTEw C . U N I N TE N D E D ME A N IN GS Another problemin the categoryof logicalexpression actuallysayswhat it intendsto say. is whetherthe sentence Often, sentenceswill intend to say one thing but actuallysay another: Examples: A childlesscharwoman'sdaughter,Dr. Robertswas a self-madewoman. If the presentinterestratesfall drastically,the dollar will losemuch of its valueon the foreign exchanse. Both of thesesentencesmay seemat first plausible,but a closerreadingwill show that eachcontainsan error of logical expression.The first exampleis actuallyself-contradictory.As written, it assertsthat Dr. Robertswas the daughterof a childlesscharwoman. In that case,Dr. Robertswould indeedhavebeena self-madewomanl What the sentence intendsto say aboutDr. Robertsis thatshewas bothchildlessandthe daughterof a charwoman. The secondsentence is a bit more subtle. It suggests that presentinterestratescan change,but that is internally inconsistent,for if the interestratechanges,the result is a new interestrate-not a changedpresentrate. The sentence can easilybe correctedby deletingthe wordpresent. In this category,thereare as many possibleexamplesas therearepossibleerrorsin humanreasoning.Therefore, when checkingfor intendedmeaning,just askyourselfwhat the logic of the sentence implies. SENTENCE STRUCTURE MAY OBSCURE INTENDED MEANING From the logical structureo[ the sentence,determinewhether the sentenceassertswhat it i n t e n d st o s a v . D. CONCISENESS Thereareendless possibilities for conciseness errors.Several examples areillustrated below. 1 . A V O I D A W K W A R D S E N T E N C E SA N D P A S S I V E V E R B S A sentence may be grammatically and logicallycorrectandyet be in needof correctionbecauseit is awkward. Examples: The giantcondoris ableto spreadits wings up to 25 feet.(Poor) The giantcondorhasa wingspanof up to 25 feet.(Better) Althoughmoststudentswould benefitfrom furtherstudyof the sciences, doing so is frighteningto most of them in thatsciencecoursesaremoredifficult thanliberalartscourses.(Poor) Althoughmost studentswould benefitfrom furtherstudyof the sciences, mostof them areafraidto take suchcoursesbecausethey aremore difficult than liberalartscourses.(Better) Giventhat the Incaslackedthe wheel,the buildingsat MachuPicchuaremore astonishingthanany Greektemplesthat arecomparableas an achievement.(Poor) Giventhat the Incaslackedthe wheel,the buildingsat Machu Picchuaremore astonishingthanany comparableGreektemple.(Befter) In eachcase,the secondsentenceis lessawkwardand clearlyrendersthe intendedthought. A common erroramongwritersis the useof the passiveverb. Eachof the following examplescontainingthe use of the weak passiveverb is then followed by a suggestedcorrectionthat rendersthe sentenceboth clear and concise. Examples: The unemploymentratebeing 4Vo,thereare as many openjobs as therearejob seekers.(Awkward) When the unemployment rateis 4Vo,thereareas manyopenjobs as therearejob seekers.(Better) ACT BASIC GRAMMAR REVIEW C- 15 Aliens,unlikecitizens,beingunableto vote,havelittle voice in Americanpolitics.(Awkward) Becausealiens,unlike citizens,arenot ableto vote,they havelittle voice in Americanpolitics.(Better) One-fourthof the marketwas capturedby the new computerfirm. (Awkward) The new computerfirm capturedone-fourthof the market.(Better) AVOID PASSIVE VERBS Any verb constructionusing a form of the verb be in addition the active verb is called a passiveverb.

E. MISPLACED MODIFIERS Anothererrorof logicalexpression is the infamousmisplacedmodifier. Generally,a modifiershouldbe placedas closeto what it modifiesas possible.A modifier which is too t-arfrom what it is intendedto modify or too closeto someotherimportantelementwill seemto modify the wrongpart of the sentence.Considerthe following faulty sentences: ExampLes: Stuffedwith herbdressing,trussedneatly,andbakedto a goldenhue,Aunt Fannieproudlyservedher famoushoiidayturkey. The doctorsaidgentlyto the patientthattherewas nothingwrong with a smile. At the tailgateparty,Fredservedcold beerto his thirstygueslsin papercups. (hat As for the first example,poor Aunt Fannie! The proximityof the introductorymodifier to Aunt Fanniesuggests Aunt Fanniewas stuffed,trussed,and baked.The sentence canbe correctedby relocatingthe modifyingphrase: Aunt Fannieproudlyservedher famousholidayturkey,stuffedwith herbdressing,trussedneatly,and bakedto a goldenhue. The secondexampleis ambiguousandcould meaneitherthat thereis nothingwrong with smiling or that the doctorsaid with a smile that nothingwas wrong with the patient. phrasein paper cupsimpliesthat it is the guests Finally, in the third example,the locationof the prepositional who are in the papercups,not the beer. The sentence can be correctedby repositioningthe modifyingphraseso that it is closerto what it is intendedto modify: At the tailgateparty,Fredservedcold beerin papercupsto his thirstyguests.

The semicolon is often used between independentclausesconnectedby conjunctive adverbssuch as consequently,therefore, also, furthermore, for example, however, nevertheless, still,yet,moreover,otherwise.Notei The adverbmust be followedby a comma. Exantples: Anne is working at the front deskon Monday;Ernie will takeover on Tuesday. She waitedfor her checkto arrive in the mail for two weeks;however,the check neverappeared.
