How do I use “whose” in a sentence?
“Whose” is an interrogative word that is used to indicate possession. It can be used in questions as an interrogative pronoun (e.g., “Whose is this?”) or interrogative determiner (e.g., “Whose phone has a blue case?”).
It is also used as a relative pronoun in adjective clauses (e.g., “My neighbors, whose dog is always escaping, are building a fence”).
Sometimes, people get confused about the difference between “whose” and “who’s.” The words sound the same but have different meanings. “Who’s” is the contraction of “who is” or “who has” (e.g., “Who’s your favorite singer?”).
