Your and you’re are two words that native speakers and non-native speakers of English both mix up. It is a very common spelling error. However, it is also easily avoidable with a bit of forethought :).
Your is a possessive pronoun. You use it to identify that something belongs to ‘you’.
- That’s your coat.
- I think your cat is super cute
You’re is a contraction (short form) of you are.
- You’re coming to my birthday party tonight, right?
- You’re not going to believe the crazy stuff that happened to me today!
A tip to prevent the error:
Read the sentence out loud after you write it. Usually when you read something out loud it is very easy to feel when something is awkward or not quite right.
