Which one is you?

The subject is you, so Which one are you?

Thanks!!

I don't know -- but a few days ago I was leafing through a novel by Sidney Sheldon, and bumped into a sentence [which one is you?] said by a doctor.

Any idea?

Mr. TomWhich of the following sounds better?Which one is you, John?Which one are you, John?

Which one is you?

because the answer is

Isn’t the subject you?, like in Who are you?

Not to me.

As I said, the answer to "Which one is you?" is "This one is me" (not "I am this one"). I take the question to be asking the listener to point at the relevant part of the photo while answering.

I find it hard to conceive of an answer like "I am this

CalifJimIt wants an answer like "I'm the third one from the left in the back row". So this is also possible, but it didn't strike me as the correct interpretation for what the OP asked.

That’s exactly what the OP meant: “when looking at a group photograph”.

I see. Well, it turns out then that the situation is more ambiguous than I originally thought. I thought the OP wanted John to point at his own image in the photo; I didn't think the OP wanted John to specify in words where his image was located in the photo.

I was seeing only the latter situation, but I don’t think it really matters either way: both answers effectively identify the person in the photo.

Besides, I don’t see anything wro
