An apostrophe can be used to replace a letter (or letters). For example:
- isn't (from is not)
- don't (from do not)
- can't (from cannot)
Apostrophes Replace Missing LettersAn apostrophe can be used to show that a letter (or letters) is missing from a word.
Using an apostrophe to replace a missing letter is not common in formal writing, where you'd expect all words to be written in full. (Using an apostrophe to replace a letter is extremely common, but it is generally reserved for informal writing. It is used to reflect how people speak.)
- The weather's bad. (Written in full: The weather is bad.)
- Don't think about it. (In full: Do not)
(In this example, the apostrophe replaces the letter i, and the two words are joined to make one. The new word is called contraction.)
In this example, the apostrophe replaces the letter o, and the two words are joined to make a contraction.)

Only Use Apostrophes to Replace Letters in Standard ContractionsWhen an apostrophe replaces a letter, a new word is formed (most often, but not always, using the remaining letters of the original words). The new word is called a contraction.
You cannot invent your own contractions. Here is a list of common contractions in English:
|he'd||he had, he would|
|he'll||he will, he shall|
|he's||he is, he has|
|I'd||I had, I would|
|I'll||I will, I shall|
|it's||it is, it has|
|she'd||she had, she would|
|she'll||she will, she shall|
|she's||she is, she has|
|that's||that is, that has|
|there's||there is, there has|
|they'd||they had, they would|
|they'll||they will, they shall|
|we'd||we had, we would|
|what'll||what will, what shall|
|what's||what is, what has|
|where's||where is, where has|
|who'd||who had, who would|
|who'll||who will, who shall|
|who's||who is, who has|
|you'd||you had, you would|
|you'll||you will, you shall|
