What you need to know about apostrophes

What is an apostrophe?

Apostrophes are punctuation marks used to indicate possession or omission in writing.

Placing an apostrophe before an "s" demonstrates ownership by a person or thing. For example, “the cat's tail” indicates the tail belongs to the cat.

Apostrophes are used in contractions too, where letters are omitted to combine two words. For example, “it’s” is a contraction of “it is.”
