Sometimes I come across "Which" being used for people.

I didn't get to see the twins very well. That's why I can't tell which is which.

Which of you ate the chocolate?

Which one is the culprit?

Which "you" is who? (I also didn't understand this sentence btw. I don't understand the grammar structure, nor the meaning)

But is that correct? Or I must say "Who(m)"?

    It's perfectly OK to use which of people when asking about the identity of one individual. May 18, 2020 at 8:38

"Which" is used for things, children or inferior animals. Besides, "which" is used "to mean selection" :

e.g. A : "I want to meet Mr. Roy." B: "Which Mr. Roy do you want to meet?" (Selection)

In all the examples given by you, "which" has been used to show this selection :

"which is which", "which of you", "which one", "which you".


The sentences are correct.

Which is an interrogative pronoun.

'Which' can be used before nouns to ask questions about people. We can use 'which' when we are choosing between a small number. We know how many options there are.

Which one, Which of you, Which of them, Which of your parents, which of your sisters, Which of your teachers, Which Farukh- Farukh the banker or Farukh the teacher?
