Question

A common grammar mistake is to mix up ‘who’s’ and ‘whose’. Which of these sentences is incorrect?
Can you tell me who’s got my jacket?
Whose clothes are these?
Who’s going to the party tonight?
Who’s books do these belong to?

Answer 1

Hey mate here is your answer..
Who’s books do these belong to? is wrong because who's means who is....

Answer 2

Though whose and who's sound same but their meaning differ. 'Who's' as a pronoun is a contraction linking the words 'who has' and 'who is' whereas, 'whose' is the possession form of 'who.'

Who as a subject pronoun which refers to she, I, he or they and is used for the interrogative purpose.

Whereas, whose as a pronoun is used in question in order to ask for possession of something or someone.

Hence, the sentences which are written incorrectly are:

a)Can you tell me who's got my jacket?

d)Who's books do these belong to?

The above sentences are wrong as word who's should be replaced by whose to show the possession of jacket and books.
