How to use do/does/did in question

Do you get confused with the action in every question like ‘Does he visit (or visits) his mother?’

This is the simple rule:

When we ask a question with do/does/did, the verb form should be in its base form. Simply put, the verb remains in its original form without ‘-s’, ‘-ed’, etc.

Thus, ‘visit’ is the correct answer to the above question.



  1. Does he know him?
  2. Do you know him?
  3. Did you know him?

The verb ‘know’ remains unchanged in the above examples because ‘does’ and ‘do’ have indicated the number (singular and plural) already, while ‘did’ indicated the tense (past).
