However, they function as adjectives in a sentence. They modify another noun by showing possession or ownership.
Here's why:
* Nouns: They name people, places, things, or ideas.
* Adjectives: They describe or modify nouns.
Example:
* The dog's bone
* "Dog" is the noun.
* "Dog's" is the possessive noun, acting as an adjective modifying "bone".
It's important to remember that while possessive nouns are nouns themselves, they have an adjectival function within a sentence.
