How do you know when its needs an apostrophe? This is one of the commonest errors — but you can get this right!
Here's a new way to remember the difference.
Its and it's belong to two different families. One family has apostrophes, the other one doesn't.
Apostrophe family: I'm, you're, he's, she's, it's, we're, they're.
Non-apostrophe family: my, your, his, her, its, our, their.
To check whether an apostrophe is needed, run through the family tree.
- He's fine. She's fine. It's fine. (All need an apostrophe.)
- His hat. Her hat. Its hat. (No apostrophe.)
