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.''
<em>Mary's</em> is a possessive noun ( because it's telling us that the book is Mary's) and <em>Mary's</em> is functioning as an adjective and modifying the noun <em>book</em>.
Examples for possessive adjectives: This is <u><em>our</em></u> house.
Hey, that's <em><u>my</u></em> phone.
Possessive adjectives list: your, my, his, her, its, our, their. Possessive adjectives can replace noun to show ownership of something.
