English Contractions: Forms and Usage

Contractions are shortened forms that combine two words by omitting letters and replacing them with an apostrophe (‘). They are common in spoken English and informal writing and help make language sound more natural and concise.

Contractions

If you have ever read a book or watched a movie, you have probably seen contractions such as can’t, I’m, or they’re. A contraction is formed when one or more letters are removed from a word combination and an apostrophe is used to show the missing letters.

A contraction is a shortened version of a word or phrase created by omitting one or more letters and replacing them with an apostrophe. Contractions are especially common in spoken English and informal writing.
