Question

whom are you talking ____ ? . put preposition​

Answer 1

Explanation:

“To whom are you talking” will be accepted as technically correct by more people, but in truth is not syntactically any better. English grammar rules were at one time modeled after Latin, which deals with infinitives and prepositions differently than English.

Modern language authorities, like dictionaries and style guides, tend to prefer a more natural construction. However, there are still some prescriptivist readers you may come across who believe in the “no preposition at the end of a sentence” rule.

Depending on your audience, you may wish to stick with the more awkward construction to avoid unwanted criticism. However, being able to explain the origin of the rule and your reason for rejecting it might be an even better choice.

The use of “whom” in this case is certainly correct, however in more casual situations “correct” may be marked as overly stuffy or even pretentious. Using “who” would be syntactically wrong, but actually more appropriate for register.
