Which pronoun case type can function as an adjective

i need about three sentences on it

Answer: I believe a possessive pronoun would be the case type.

I JUST TOOK THE TEST.

Possessive pronoun is what you are looking for.

Examples of possessive pronouns:

The kids are Yours and Mine.

We shall finally have whats rightfully Ours.

The Dog is Mine

The Cat is Yours

(So essentially a possessive pronouns are anything involving anything with possession as above.) Such as What is mine is yours etc.

Or the Playstation Four is mine but, the xbox one is yours.
