1.What are you watching? I’m watching a horror movie.
2.Where are you working? I’m working in my office.
3.Where are you cleaning? I’m cleaning the kitchen
In order to find out the underlined part, we use a question word.
In sentences 1,”a horror movie” is the object of the sentence and a question word “What” works fine.
In sentence 2,” in my office” is not the object but a modifier, telling the asker the place where I’m working, so a question word “where” is OK.
What about sentences 3? “the kitchen” is the object of the sentence.
Is “where” grammatically acceptable as a question word?
Or is there a better interrogative sentence asking what part of the house, or which room is being cleaned?
