What are pronoun-adjectives?

Answer 1

The pronouns that function as adjective are the possessive adjectives.

A possessive adjective is placed before a noun to describe that noun as belonging to someone or something.

The possessive adjectives are: my, your, his, her, their, its.

Examples:

My house is the one with the blue door.

These are their vacation photos.

His flower shop is on Third Street.

Possessive adjectives should not be confused with possessive pronouns, words that take the place of a noun that belongs to someone or something.

The possessive pronouns are: mine, yours, his, hers, its, ours, theirs.

Examples:

The house with the blue door is mine.

These vacation photos are theirs.

The flower shop on Third Street is his.
