Your

Your refers to something that belongs to you. This should not be confused with you're, which is a homophone of your, but you're means "you are".

Example

 * Your stone. (Means a stone belonging to you.)
 * You're stone. (Means you are made of stone.)
 * You're stone-hearted. (Taken literally, means your heart is made of stone. An expression meaning that you are a distant or cruel person.)
 * You're stoned. (Means you are high on drugs.)
