Confusing Words

your vs you're

These two words sound exactly the same, which makes them easy to mix up when writing.

  • your — Your' is a possessive pronoun, used to show that something belongs to the person you are talking to — for example, Is that your book on the desk?
  • you're — You're' is a contraction of 'you are', so it can always be replaced with those two words — for example, You're doing a great job (meaning 'You are doing a great job').

Memory rule: Before writing either word, try replacing it with 'you are'. If that makes sense, write 'you’re'; if not, write 'your'.
