I have to find the verb and predicate nouns and predicate adjectives.

1.) Their uniforms are a symbol of their authority. Verb=are PN=symbol

Right!

ok, thanks.

2.) Now they are famous throughout the world. Verb=are PA=famous

Right again!

3.) They are the subject of many stories. Verb= are PN=subject

You are correct.

thank you

To find the verb and predicate nouns and predicate adjectives in a sentence, you need to understand the structure of a sentence.

In the given sentence, "Their uniforms are a symbol of their authority," the subject is "their uniforms" and the verb is "are."

Now let's identify the predicate nouns and predicate adjectives.

A predicate noun is a noun that comes after a linking verb and renames or identifies the subject. In this sentence, the only noun that renames or identifies the subject is "symbol," so "symbol" is the predicate noun.

A predicate adjective is an adjective that comes after a linking verb and describes the subject. In this sentence, there are no adjectives that describe the subject "their uniforms," so there are no predicate adjectives.

Therefore, in the sentence "Their uniforms are a symbol of their authority," the verb is "are," the predicate noun is "symbol," and there are no predicate adjectives.
