Not to be a grammar snob, but it’s really not that difficult.
Think back to 1st grade. Remember when we learned about contractions? And how when you wanted to put two words together, you take out some letters and add an apostrophe? Well kids, just because you moved on to 2nd grade doesn’t mean you forget those rules. In fact, using the correct word only becomes more essential.
So, just a quick explanation: “you’re” means “you are.” Example: “If you don’t move, you’re going to get hit by the blimp.”
Not-so-similarly, “your” is used to denote possession. Example: “I accidentally lit your Justin Bieber poster on fire.”
Seriously, it’s both a spelling AND a grammatical mistake within the span of 4 to 5 letters. Quite a feat. Yet also easily avoidable.
Note: Readers, if you ever find that I have used the wrong “Your/You’re” anywhere in this blog, you have my full permission to post nasty comments. Not that you really needed that in the first place, just sayin’.
