The interrogative form

The interrogative form is different if the verb is an ‘auxiliary’ verb (to be, to have, will, can, etc.), or a ‘normal’ (non-auxiliary) verb.

Interrogative of auxiliary verbs

  • If the verb is an auxiliary verb, the interrogative is formed without the auxiliary do/does/did.


  1. Are you Japanese?
  2. Can I ask you a question?
  3. Can I talk to you?
  4. Have you read this book?

Interrogative of normal verbs (non-auxiliary verbs) 

  • If the verb is ‘normal’, the interrogative is formed with the auxiliary do/does/did. As always after an auxiliary verb, the verb is added in the infinitive without to.


  1. Did she see the movie?
  2. Do you speak English?
  3. Does Rubina live in USA?
  4. Do you like that album?

Inverting the auxiliary to form the interrogative

  • The interrogative sentence is formed by inverting  (changing the position) the first auxiliary verb.


  1. You would tell me. => Would you tell me?
  2. You can swim. => Can you swim?
  3. Fenil is lucky. => Is Fenil lucky?

Note: The ‘normal’ verb to do is also conjugated with the auxiliary do/does/did.


 1.  Does he do his homework on time?

– In the case of interrogatives introduced by pronouns (Who, What)

  • If the interrogative pronoun is a subject, there is no inversion:
  1. Who told you this?
  2. Who is here?
  • If the interrogative pronoun is an object, there is an inversion:
  1. What did he say?
  2. What are you thinking about?
