Why syntax?

It’s part of Linguistics It’s part of the grammar of every

language And the grammar of a language is

part of a native speaker’s linguistic knowledge

Syntax Dr Alok K Das

Page 4: Syntax Das

Reasons for studying syntax Infinity of expressions

There is an infinite number of possible utterances in every language

It is obvious that all these utterances cannot be stored in our brains

Our knowledge of a language consists of A finite number of words (the lexicon; the

“dictionary in your head”), and Rules (the grammar of the language)

It is the job of the syntactician (and the morphologist) to find out what these rules are

Syntax Dr Alok K Das

Page 5: Syntax Das

Language acquisition Everyone who can speak knows how

to use the rules and it is amazing that children can do it

so fast But nobody can really state exactly

what the rules are! Understanding syntax (and

morphology) can help researchers to understand how young children learn their native language

Syntax Dr Alok K Das

Universal grammar

Theory of Chomsky UG has Principles, true of all languages

All languages have the same underlying structure e.g. all languages have nouns and verbs

and Parameters, whose setting varies from language to language English and Chinese SVO; Japanese SOV Spanish and Chinese pro-drop; English not

pro-dropSyntax Dr Alok K Das

Page 7: Syntax Das

7

All languages have constituents Take a simple sentence

Johnny danced We can call the sentence S, and label the syntactic

categories N and V

S

N Johnny

Vdanced

Syntax Dr Alok K Das

Page 8: Syntax Das

8

Phrase structure grammar N and V aren’t always

very good labels Johnny is similar to the

handsome student, because they are both the same kind of constituent They are both Noun

Phrases We can remove

Johnny and add the handsome student, and the sentence structure is still similar

S

NPThe handsome student

VPdanced

Syntax Dr Alok K Das

Page 9: Syntax Das

9

Different sentence, same constituents

Now let’s add an object danced the lambada is

the same kind of constituent as danced a VP

You can swap danced for danced the lambada and the basic structure is the same

S

NPThe handsome student

VPdanced the lambada

Syntax Dr Alok K Das

Page 10: Syntax Das

What are the NP and VP? The frog ate the lizard. The frog sat on the lilypad. The fat frog ate the long lizard slowly. The fat frog with a lizard in its mouth

sat on the lilypad. The fat frog who was sitting on the

lilypad with a lizard in its mouth danced the lambada.

Syntax Dr Alok K Das

Page 11: Syntax Das

Phrase structure rules Now, you know this phrase structure rule:

S NP VP (a Sentence comprises a Noun Phrase followed by a Verb Phrase)

Draw a tree for the phrase Emma drinks Here are two more phrase structure rules:

VP V NP NP N

Think about that carefully Now, draw a tree with more detail

For the sentence Emma drinks whisky

11Syntax Dr Alok K Das

Page 12: Syntax Das

12

Now let’s change the NP rule First, DET means determiner

Function words like the, a, this, several NP (DET) N

That means a noun phrase can have a determiner, and it must have a noun

Now you can diagram Johnny danced the lambada in a bit more detail than I did on the other slide

Remember: S NP VP VP V NP)

Syntax Dr Alok K Das

Page 13: Syntax Das

13

Now let’s change the NP rule again

Such that we have S NP VP VP V NP NP (DET) (ADJ) N

Now you can diagram this sentence The unhappy book ate the green lambada The sentence is syntactically well-formed,

by the way

Syntax Dr Alok K Das

Grammatical or Ungrammatical:

1. The boy found the ball2. The boy found quickly3. The boy found in the house4. The boy found the ball in the house5. Disa slept the baby6. Disa slept soundly

Find: Transitive verb (with object)Sleep: Intransitive verb (no object)

14Syntax Dr Alok K Das

Syntactic Categories

Lexical categories Noun (N) Verb (V) Adjective (A) Preposition (P) Adverb (Adv)

Examples moisture, policy melt, remain good, intelligent to, near slowly, now

15Syntax Dr Alok K Das

Page 16: Syntax Das

Syntactic Categories

Non-lexical categories Determiner (Det) Degree word (Deg) Qualifier (Qual) Auxiliary (Aux) Conjunction (Con)

Examples the, this very, more always, perhaps will, can and, or

16Syntax Dr Alok K Das

Page 17: Syntax Das

Indicate the category of each word in the following sentences.

a. The glass suddenly broke.

b. A jogger ran towards the end of the lane.

c. The peaches never appear quite ripe.

d. Gillian will play the trumpet and the drums in the orchestra.

Det / N / Adv / V

Det / N / V / P / Det / N / P / Det / N

N / Aux / V / Det / N / Conj / Det / N / P / Det / N

Det / N / Qual / V / Deg / A

Phrases

NP : Noun PhraseThe car, a clever student

VP : Verb Phrasestudy hard, play the guitar

PP : Prepositional Phrasein the class, above the earth
