Possessive Nouns are often used as adjectives true or false

Answer: Possessive nouns have function as adjectives

Explanation:

Possessive nouns are showing ownership and they have an apostrophe or ''s'', or both. For example: Today's weather, Mary's book, Dog's food, Owls' eyes.

Because of that, they function as adjectives but they are still possessive nouns.

''I can't find Mary's book.''

Mary's is a possessive noun (because it's telling us that the book is Mary's) and Mary's is functioning as an adjective and modifying the noun book.

Examples for possessive adjectives: This is our house.

Hey, that's my phone.

Possessive adjectives list: your, my, his, her, its, our, their. Possessive adjectives can replace noun to show ownership of something.

No, possessive nouns cannot be used as adjectives.

Explanation:

Possessive noun shows the ownership and possessive adjective defines and modifies the noun to show the ownership. Possessive adjectives are not formed by adding apostrophe + s to possessive noun.

Possessive adjectives are my, your, his, her, its, our, their. The possessive pronouns that replace the noun are: mine, yours, hers, his, its.

For example: his head is big. (His is possessive adjective)

That money is ours. (Ours is possessive pronoun)
