This is from a cartoon I want my dummy See (3:37-3:40)
Someone's dummy was taken away by someone in the house, so she is looking for it and questioning everyone in the house to find out who has taken it. And when she sees someone, she says:
"Did you take it?"
I wondered why she said "Did you take it", because this is a structure that tries to find whether the person took it or not. It is not a structure that seems to focus on who it was that took the toy.
Instead,I would have expected a question like this:
Is it you who have taken it? or "Was it you who took it?"
These structures seem to focus on the doer of the action, rather than the action itself.
So, my question is: Is it ok to use "Did you take it?" to mean "Was it you who took it"?
