Who’s and whose

“Who’s” means “who is” (“i” omitted) or “who has” (“ha” omitted).

“Whose” indicates that something belongs to someone or something. 


Who’s going to the party? (Who is going to the party?)

Who’s left a pool of water in the bathroom? (Who has left a pool of water . . .)

Sheila, whose eyes were red, had been crying for most of the morning. (Indicates that the eyes belong to Sheila).


“Whose” is often used in questions such as: “Whose bicycle is this?” If you are ever confused as to whether “whose” or “who’s” is correct, try putting in the full version of “who’s” i.e., “who is”. “Who is bicycle is this?” is clearly wrong, so you know it must be “whose”.
