Question words


Questions about the subject


When we ask questions about the subject of a sentence, the word order in the question and the answer is the same:

Ben designed this house.

Who designed this house?

X Who did build this house?

Who built this house?

  • We use what, who, which, whose and how many in questions about the subject.

Questions about the object

Questions about the object need an auxiliary verb (do, have, is, etc.) before the subject:

John designed this cathedral.

What did John design?

  • We use what, which, who, whose, when, where, how often, etc. in questions about the object.
    X Which cathedral John built?
    Which cathedral did John build?
