I just received an email from the ASUFACULTY-STAFF-INFO listserv from the Office of General Education inviting me to a reception honoring some recent award winners. I wish the subject line had read:
- You're invited
Here is how they explain the problem at Yahoo!
A good way to remember this is to realize that YOU'RE is short for "You are" (i.e. "You are invited"). The apostrophe (') replaces the "A" in "ARE". Other versions of this type of word are: I'm . . . he's . . . she's . . . we're . . . they're . . .
YOUR is just a possessive pronoun, the opposite of MY. For example, "I like your shoes" "Is it your birthday?" YOUR only relates to things that belong to someone.
