Why the question 'About what are you talking?' is incorrect? and
The question "To whom are you talking" is correct?
I know the question 'what are you talking about?' is the correct question.but why can't we move the preposition 'about' before what(like 'To whom are you talking')
Practical English Usage (Michael swan's) (page 466) says,
"Prepositions often come at end of wh-questions,separated from their objects.
......e.g:-What are you talking about? (Not -About what are you talking?)
...........-Who did you buy the ticket from?.."
