This episode takes a look at the expression “cup of tea” and the main uses of “whose” and who’s.” Tip: “whose” and “who’s” are pronounced exactly the same. They rhyme with “shoes.” Remember, we use the possessive pronoun “whose” to ask whom something belongs to: Whose car is that? “Whose” is also used to tell whom something belongs to: My friend, whose car broke down, is angry. In regards to “who’s,” remember that it can either be the contraction of “who is” or “who has.”
