Grammar has certain rules that plenty of people find difficult to follow and some tricky words that often sound the same but have very different meanings. One of these grammar rules is the difference between the use of your and you're. Do you know the difference? Similar to other pairs like whose and who's, the pairing you're and your often causes confusion. You're is a contraction and is short for the two words ‘you are'. The apostrophe stands for the omitted ‘a' of ‘are'. Your is a possessive determiner and pronoun which means ‘belonging to you'.
