Your

Your: The possesive to mean "That is yours." or "That's your car over there isn't it?" not to be confused with "You're" which means "You Are", if you use this one to mean your then you fail and should be punished for terrible use of grammar.

= ur =

This is the short hand way of writing either Your or You're, there is nothing different when you write it this short, other than it makes you look like a really clever person and everyone will stand back in amazement at your Intellect.
