Forming Questions

English questions require specific word order changes.

Yes/No Questions

Questions answered with “yes” or “no”.

With Auxiliary Verbs

Pattern: Auxiliary + Subject + Main Verb

StatementQuestion
She is working.Is she working?
They have finished.Have they finished?
He can swim.Can he swim?
We will go.Will we go?

With “Do/Does/Did”

When there’s no auxiliary, add do/does/did:

StatementQuestion
You like coffee.Do you like coffee?
She works here.Does she work here?
They went home.Did they go home?

Note: Main verb returns to base form:

  • She works → Does she work?
  • They went → Did they go?

With “Be” as Main Verb

“Be” moves before the subject:

StatementQuestion
She is a doctor.Is she a doctor?
They are ready.Are they ready?
He was late.Was he late?

Subject vs. Object Questions

Object Questions (normal pattern)

The question word replaces the object:

  • You saw someone. → Who did you see?
  • She bought something. → What did she buy?

Subject Questions (no auxiliary needed)

The question word replaces the subject:

  • Someone called. → Who called?
  • Something happened. → What happened?

Compare:

  • Who called you? (subject question - no “did”)
  • Who did you call? (object question - needs “did”)

Negative Questions

Often express surprise or seek confirmation:

  • Don’t you like it?
  • Isn’t she coming?
  • Haven’t you finished?
  • Why didn’t you tell me?

Tag Questions

Short questions at the end to confirm:

Pattern: Positive statement → negative tag (and vice versa)

  • You like coffee, don’t you?
  • She isn’t coming, is she?
  • They have finished, haven’t they?
  • He can swim, can’t he?
