- Yours is a pronoun. It shows possession from a second person point of view.
- Yours never has an apostrophe (Your's is incorrect).
- it replaces "your noun" (Your watch, your computer, your haircut).
Examples:
- I don't like my new haircut, but yours is cute!
- my dog is crazy, but yours is so calm.
- my computer is slow, but yours is fast.
- Ok, I bought everyone's ticket to the game. *gives the tickets out to the group*
