Whose vs. Who's
Who's = who is or who has. Whose = belonging to whom.
Who's is a contraction: who is or who has. "Who's coming to dinner?"
Whose is possessive: "Whose book is this?"
Same rule as it's/its. If "who is" works, use who's. If you're showing ownership, use whose.
Examples
Whose going to the meeting?
Who's going to the meeting?
Who's book is this?
Whose book is this?
Frequently asked questions
No. You can ask "Whose turn is it?" for things, places, or ideas.
