When do we use might and might not?


might (not)= Maybe it is (not) true

We use might, might not when we think something is (not) or will (not) be true, but we aren’t sure.

  • ‘Suzan isn’t answering the phone.’ ‘She might be in the garden.’
  • The sky is clearing up. It might not rain this afternoon. 
  • They might win the competition. 


I might (not)= It is possible that I will (not)

We say that someone might do something to mean that ‘it is possible that someone will do something‘.

  • I might go for a run this afternoon. (=It’s possible that I will go for a run.)
  • She might come to the conference.

We say that someone might not do something to mean that ‘it is possible that someone won’t do something‘.

  • I might not come to the party. (=It’s possible that I won’t come to the party.)
  • He might not go to work tomorrow. 


may, may not


may= might

We can use may and may not instead of might and might not.

  • She may be late for class this morning. 
  • They may not like your decision. 


May I … ?

We don’t often use might or may in questions. However, we can use may I in questions to ask for permission.

  • May I sit here? (=Can I sit here?)
  • May I come in?
