Your VS You're

Your: belonging to or associated with any person.

Is this your highlighter I'm using?

I nearly forgot, today is your birthday!

You're: contraption of you are; most likely going to be followed by an adjective or verb.

You're amazing, George.

You're going to basketball practice tonight, right?

How to Remember:

Put in "you are" in your sentence and see if it works. Incorrect: "You're basket is over there, by the tree." . . . because this is incorrect: "You are basket is over there, by the tree." Correct: "Your basket is over there, by the tree."
