How to use apostrophes in contractions
You can use apostrophes to show that you have omitted (left out) some letters when you are joining words together.
For example, you can join the words ‘you’ and ‘are’ together. You + are = you're. The apostrophe takes the place of the removed letters. In this example, the letter a.
Sometimes, however, you need to rearrange the letters a bit when you contract the words. For example: will + not = won't.
Using contractions like these makes your writing easier to read and more friendly.
