Who's and whose are easy to confuse. Who's means who is or who has. Whose shows possession (e. g. , never trust a doctor whose plants have died).

For example, who's coming to the party tonight? Who's been to chicago? In the first sentence, who's stands for who is. Who is coming to the party tonight?. Who's is a contraction of who is, as in who's there? And the friend who's calling, or of who has, as in who's got the time? and the friend who's helped before.
