Traditional grammars define nouns as naming people, places, things, and ideas. Noun phrases consist of a noun including a pronoun and any modifiers, complements, and determiners that provide more information about the noun or pronoun. A pronoun is word that takes the place of a noun, noun phrase, noun clause, or other nominal form. Pronouns are a subcategory of nouns.
In grammar, a subject complement is a word, phrase, or clause that follows a copular, or linking, verb and describes the subject of a clause. A noun that performs the grammatical function of subject complement is also called a predicate nominative or predicate noun. In addition to nouns, pronouns may also perform the function of subject complement. Examples of pronouns as subject complements include the following:
- This is she. (personal pronoun)
- The winner was you. (personal pronoun)
- The grand prize is that. (demonstrative pronoun)
- Your entry for the science fair is what? (interrogative pronoun)
- The group leader will be who? (interrogative pronoun)
- My daughter will become somebody. (indefinite pronoun)
- You resemble somebody I know. (indefinite pronoun)
- The strange man in the video remains nobody important. (indefinite pronoun)
