Question

Barb is confident that her students know and understand the use of phrase structure rules.
-Barb is a noun, is(linking verb), that(Comp Cl), her (noun), students (noun), know(verb), and(Conjunction),understand (verb), the (article), use (?), of (preposition), phrase structure rules (?)
-Does anyone know what the words use and phrase structure rules represent?

Answer 1

subjects?
Forget that!

"Use" must be a noun using your explanation.
"Phease structure rules" is the subject of the verb "represent" so it is a noun , the same as Babe.

Answer 2

First, 'her' is a pronoun, not a noun, though it functions similarly to a noun (a pronoun stands in place of a noun).

Part of your problem is that you're going word-by word, when what you need to do is break the sentence into parts -- not individual words, but hunks of words, based on what their role is in the sentence.

The biggest hunks are the bit at the beginning (Barb's confidence), at the rest, which is all a sentence -- being an expression of Barb's belief.

So you can look at all that stuff as also needing to be broken into subject-predicate, then those hunks can be analyzed.

"the use" is a noun phrase -- notice the 'the' -- generally a tip off that we're talking noun after the article, unless it's going to be adjectives THEN noun.

That's why you want to look at the whole noun phrase, first (bigger hunks, not word by word).

'the use' is an abstract thing -- THING. 'a use' 'one or more uses' -- 'use' is functioning as a noun in this sentence.

"phrase structure rules" is also a chunk, and also a noun phrase.

'rules' is the noun in the noun phrase (the noun in a noun phrase frequently comes last -- it's the 'thing' you're actually talking about, the other words refine, modify, or describe it.

Barb is confident her students know the use of rules -- a stripped down version.

'phrase structure' are words modifying 'rules' -- explaining which rules. Thus they are adjectives. Even though each word is often used as a noun, in this sentence, they are there to say what kinds of rules Barb is confident her student's get, as it were.

The rules about the structure of phrases (which is what I'm babbling about throughout this answer).

You first need to understand the structure of the sentence as a whole, then it's biggest parts, then the next biggest divisions, until you get to the individual words in the sentence.

Answer 3

(use) is a noun in this sentence because it follows "the". (of phrase structure rules) is a prepositional phrase.
OR
You could say that (of) is a preposition and then (phrase) would be an adjective describing rules and (structure) would also be an adjective describing rules and then (rules) would be the object of the preposition

Hope this helps!

Answer 4

I believe...
"use" - verb
"phrase, structure" - adjectives describing the kinds of "rules"
"rules"- noun

Answer 5

Her is a pronoun.

Use is a noun.

Phrase structure rules are nouns.

I hope this helped!

Answer 6

use is direct object
phrase is adverb modifying adjective structure
structure is adjective modifying rules
rules is possessive noun (possesses use)
