A noun is a person, place or thing as identified in a sentence. A possessive noun is a noun used in a sentence to show ownership. In the sentence "John's ball was lost the other day," the phrase "John's ball" indicates possession, and "John's" is the possessive noun. John owns the ball, another noun, that got lost.

Here are some of the most commonly used possessive nouns with example sentences: 1. She dropped the baby’s toy. 2. He painted the dog’s house. 3. I wore my friend’s cap.

This is the boys’ bedroom. My parents’ house is a lovely old one. The scissors’ handles just snapped off. The Jeffersons’ yard is always beautifully landscaped. The possessive case of irregular plural nouns that don’t end in s is formed by adding -’s. This is the way to the men’s meeting. She got a job in the children’s section of the library.

We add 's to singular nouns to show possession: We are having a party at John's house. Michael drove his friend's car. We add ' to plural nouns ending in -s: This is my parents' house.
