Here are a few ways to form possessive nouns:
* Adding 's to singular nouns:
* "the dog's bone"
* "the girl's toy"
* Adding an apostrophe to plural nouns that end in s:
* "the boys' shoes"
* "the girls' dresses"
* Adding 's to plural nouns that don't end in s:
* "the children's books"
* "the women's hats"
Possessive nouns are essential for showing ownership or relationships. They help us understand who or what something belongs to.
