Midterms back
Chapter 5 Exx: 2, 3, 4, 9, 11 (Give surface and deep structure for 11
– no trees) due 5/15
Problem Set 4 due 5/20
Goals for syntax chapter
 Not responsible for Section 4 (Verb raising) or how to do passive
sentences
 You should know how to do the following:
 identify the lexical/syntactic category of word
 construct phrases and simple sentences and sentences with embedded
sentences (draw trees for these structures)
 apply different movement operations to derive surface structure
forms from deep structure
Determine how a sentence is structurally ambiguous (from Ch 6 – 3.2)

Syntax
 The part of the grammar that combines words into sentences
 The study of the system of rules and categories that underlies sentence
formation.
The goal of syntax is to come up with universal principles (Universal
Grammar) that describes all languages phrase formation procedures
Syntax is responsible for the hierarchical structure of phrases and their
creation
The goal of syntactic theory is to be boring and repetitive (i.e. systematic and
universal)
Think of syntax as a template for sentence formation that can operate for all
sentences for all languages

 Syntactic Categories
 Lexical categories: Noun (N), Verb (V), Adjective (A), Preposition (P) and
Adverb (Adv)
 Nonlexical Categories: Determiner (Det); Auxiliary Verb (Aux) - Modal and
Nonmodal; Conjunction (Con); Degree word (Deg)
 Table 5.1, p. 157 (on next slide)
 Harder to define nonlexical words (the or so compared to hill or book)
 Some words can belong to more than one category - examples? like/fond

Lexical:
words that have semantic content
words that can be inflected
an open class to which new
members can be added
includes nouns, verbs, adjectives,
adverbs and prepositions
Nonlexical:
words that have grammatical function
words that do not have morphology
words that resist change
a closed class to which new members
are not added
includes determiners, auxiliary verbs,
degree words, qualifiers, pronouns,
conjunctions, complementizers, and

How to determine syntactic category – MEANING TEST
Noun = person, place or thing (Jeff, classroom, book)
Verb = action, sensation, state of being (run, loves, sees, be)
Adjective = describes a noun (green, ugly)
Adverb = describes a verb (quickly, slowly)
Preposition = describes physical location (to, for, from, on, in)

How to determine syntactic category – INFLECTION TEST
Only certain inflectional suffixes attach to certain lexical categories
There are some words that belong to these syntactic categories that do not
take these suffixes (*funner, *intelligenter)
Category
Inflectional Affix
Examples
N (Noun)
plural -s
books, chairs, doctors
possessive -’s
John’s, (the) man’s
past tense -ed
arrived, melted, hopped
progressive -ing
arriving, melting, hopping
3rd person sing. -s
arrives, melts, hops
comparative -er
taller, faster, smarter
superlative -est
tallest, fastest, smartest
V (Verb)
A (Adjective)

How to determine syntactic category – DISTRIBUTION - SPECIFIERS
Determiner = specifies a noun (the, a, these, that)
Adverbs = specifies a verb (always, often, never)
Degree = specifies an adjective or preposition (very, quite, really)
So you can tell a N if it can occur after a Det
A V can occur with an Aux verb
An Adjective with a degree word
Look at Exercise 2
Syntax

 Phrase Structure - units of words, but not sentences = phrases
 Each phrase consists of the head, a specifier and a complement
 The way the book groups phrases is called X' (X bar) where X stands for
whatever category you’re dealing with (Noun, Verb, Adjectives, Prepositions)

Phrase structure rules
The preceding examples show that any given phrase can be composed of a
mandatory head and optional complement and optional specifier. This is
written as:
XP  (Spec) X (Comp)
The optional components are written in ( )s.
From previous examples we have the following:
NP  (Det) N (PP)
AP  (Deg) A (PP)
VP  (Adv) V (NP)
PP  (Deg) P (NP)
Can you think of any other possibilities?

Complement Clauses (embedded sentences)
Think about this sentence
I wonder if she will take the test.
How do we incorporate the second sentence: she will take the test?
This second sentence (called a complement clause or CP) is serving as the
complement of the V wonder
Like all other syntactic structures, CPs consist of: CP  C ' and C '  C IP
Words such as that, whether and if are known as complementizers (C).
The specifier position is open for Move operations (discussed later)
Matrix clauses are the largest clause that contain the CP(s)
[I wonder [if she will take the test.]]

Structural Ambiguity
We have been presenting different phrase structure trees to show the
hierarchy and relationship of the different phrases in a sentence. What
happens when the difference in the relationship of these phrases also
causes a difference in the meaning/interpretation of a sentence?
When there are two or more interpretations of one sentence with the exact
same words in the exact same order, we call this structural ambiguity
(discussed in your text in Chapter 6, section 3.2).
Syntax

Structural Ambiguity
For example: Sam ate the cake in the kitchen. (See handout for answers)
What are the 2 meanings? What is the relationship between the phrases
in the sentence (what modifies what?)
Interpretation 1: Sam ate the cake that was in the kitchen.
Relationship of phrases in the sentence: The PP in the kitchen modifies the N cake
Interpretation 2: Sam was eating the cake in the kitchen.
Relationship of phrases in the sentence: The PP in the kitchen modifies the V ate

Questions?
Following our rules for sentence structure how do we
account for questions?
Is the man intelligent?
Can you come to dinner?
In the first example, there is no NP to the left of the IP
and in the second, the modal is before the subject.
To explain this we will use the theory of:
Deep Structure.
Syntax
Slide 58
Syntax
Deep Structure
Accounting for sentences such as questions and passives with
a new set of rules would be messy.
Transformational grammar accounts for the differences with
transformations (move). All sentences in deep structure
(before the move) will follow our previous phrasal rules.
{Parallel with Underlying Representation and rules to derive
surface representation in Phonology}
How do we know deep structure exists?

Syntax
Arguments for Deep Structure
What will you say?
In this sentence What is functioning as the object of the
sentence.
This can be demonstrated by trying to add an object after the
verb.
* What will you say goodbye.
In this sentence, the verb requires an object, so omitting it in
the non-question form does not work
* You will say
