Understanding Possessive Nouns

A possessive noun shows that something belongs to someone.

Basic Rule

For most singular nouns:

• Sarah → Sarah’s bike
• John → John’s car
• Emma → Emma’s bag

The confusion starts when a singular name already ends in s.

Example

• James → James’s car
• Charles → Charles’s office
• Chris → Chris’s laptop

Many grammar experts support this rule because the noun remains singular.
