Examples:
- The dogs are barking.

What Is a Possessive?
A possessive shows that something belongs to someone or something.
How to form possessives:
- Singular noun → add ’s
- boy → boy’s hat
- Plural noun ending in “s” → add ’

- Irregular plural (no “s”) → add ’s
- men → men’s shoes
Examples:
- The girl’s bag is pink.
- The boys’ classroom is upstairs.
