How to use Apostrophes

Grammar Basics

Apostrophes

Apostrophes are used to shorten words or make contractions:

Contractions are normally used in spoken English or in informal writing. They shouldn’t be used in the academic writing tasks.

Apostrophes can also show possession:

John’s book

Mary’s brother

Possessive pronouns (like ours, theirs, his, its, etc.) don’t use apostrophes:

The cat broke it’s tail.

🗸 The cat broke its tail.

The book is not their’s, it’s our’s.

🗸 The book is not theirs, it’s ours.
