Review

If you need a review on parts of speech and phrases, then follow these links:

Syntactic Categories

S, NP, N, VP, V, PP, P, AP, A, D

Evidence for Syntactic Constituents

(Based on Radford (1988), Chapter 2)

Only phrasal constituents (i.e. whole phrases) can undergo Preposing

(1) I cant stand your elder sister.

(2)

a. Your elder sister I can’t stand.
b. * Your elder I can’t stand sister.
c. * Elder sister I can’t stand your.
d. * Sister I can’t stand your elder.
e. * Your I can’t stand elder sister.

Pronouns

Pronouns replace NPs

(6)

a. SPEAKER A: What do you think of [ NP the [ N guy] who wrote that unbelievably boring book onTransformational Grammar]?
b. SPEAKER B: I can't stand [ NP him].
c. SPEAKER B: *I can't stand [ NP the [ N him] who wrote that unbelievably boring [ N book] onTransformational Grammar]

there replaces PPs

(8)

a. SPEAKER A: Have you ever been [ PP to Paris]?
b. SPEAKER B: No, I have never been [ PP there].

do so replaces VPs

(9) Lilly [ VP went home early].
(10)

a. Sandy [ VP did so] , too.
b. Sandy will [ VP do so], too.
c. Sandy might [ VP do so], too.

The S rule

S -> NP VP

Exercise 1 Find constituents

Determine the constituency of the bracketed expressions in the following sentences. Use only the following syntactic categories: S, NP, N, VP, V, PP, P, AP, A, D.

(1) John [disappeared].
(2) the bottle [broke].
(3) Martha [stayed at the hospital].
(4) Fred [talks about Chicago].

(9) we [moved it into the room].
(10) Fred [took Alice to the hospital].
(11) John [sent Martha a check].
(12) we [gave Fred a wastebasket].

Exercise 2 Draw trees

Using only the syntactic categories listed above,

a. draw plausible phrase structure trees for the odd-numbered sentences. Assume that the bracketed expressions are VPs.

Draw the trees with the program at the following website:

jsSyntaxTree

Example: to draw a tree for sentence (12) above, paste the following line into the textfield of jsSyntaxTree:

[S [NP [N We]] [VP [V gave] [NP [N Fred]] [NP [D a] [N wastebasket]]]]

A phrase structure rule is well formed, if it is of one of the following forms

C0 -> C1
C0 -> C1 C2
C0 -> C1 C2 C3

and each C is one of the categories listed above.

b. Write the phrase structure rules needed to license the trees you drew.
