Possessives are used to show ownership or relationship between two nouns. They indicate that one noun belongs to or is associated with another noun.

To form a possessive, you generally add an apostrophe (‘) and an “s” to the end of a singular noun. For example, “the dog’s bone” indicates that the bone belongs to the dog.

If the noun is plural and already ends in “s,” you only need to add an apostrophe after the “s.” For example, “the dogs’ bones” indicates that the bones belong to the dogs.

If the noun is plural and does not end in “s,” you add an apostrophe and an “s” to the end of the noun. For example, “the children’s toys” indicates that the toys belong to the children.

It’s important to note that possessives are not used with pronouns like “his,” “hers,” “theirs,” etc. These pronouns already indicate possession. For example, “That book is hers” indicates that the book belongs to her.

Possessives are commonly used to indicate ownership, relationships, or characteristics. They help clarify who or what something belongs to in a sentence.
