Let's take the affirmative sentence: Peter must go there. Can I ask such a question: "Must Peter go there?" Or only "Does Peter have to go there?" is correct?

  • I am glad to hear that I can start the question with "must". My grammar test says it is wrong. Perhaps the test is not perfect itself. – Alexander Mar 18 '17 at 8:05

Yes, you can begin an interrogative sentence with a modal verb,

Must I do this?
May I do this?
Can I do this?
Should I do this?
Would I do this?


  • I'm very glad indeed to read that "must I do this ?" is correct ! All my teachers have always told me it was wrong, obliging me to write "do I have to do it ?" is it recent form ? Was it considered as wrong 20 years ago ? – Anne Jul 5 '18 at 19:12
  • This may be a difference between US and UK usage. "Must I ___?" sounds a little stilted to this US English speaker, but I feel like I've seen it in UK usage. Hopefully a UK native speaker can address this. – stangdon Jul 5 '18 at 21:18
