Choose a question word for the information you need and form a clear question.

The idea

Use where for a place, when for a time and what for a thing or action. With an auxiliary, the usual order is question word, auxiliary, subject and main verb: Where do you live? If who itself is the subject, an ordinary affirmative question uses subject–verb order without auxiliary do: Who called the office?

Examples

  • Where do you live?
  • When does the shop open?
  • Why are they late?
  • What did you buy?
  • Who called the office?
  • Which bus goes to the museum?

Watch out

Do not insert an unneeded did into a neutral subject question: Who called? asks who performed the action. Who did you call? asks about the person called and has a different structure.
