May and Might – English Modal Verbs


May and Might are modal verbs.

They can normally be interchanged without a significant difference in meaning.

  • I might go
  • I may go

May and Might more or less have the same meaning. (We will see more about this later)

With modals verbs, there is only one form of them for every subject pronoun.

For example with the modal verb MIGHT. We say…

  • I might
  • You might
  • He might
  • She might
  • It might
  • We might
  • They might

The same happens with MAY … I may, you may, he may, she may, it may, we may, they may.

Just like the other modal verbs, there is never an S at the end of may or might:

  • She mights stay. (This is NOT CORRECT)
  • She might stay. (This is CORRECT)

After MIGHT or MAY we have the verb, or more specifically, the base form of the infinitive.

This means the infinitive without To. For example the infinitive is To Go so the base form is just the Go part.

Instead of To Study, only study. Instead of To speak, we only put Speak after the modal verbs MIGHT and MAY.

For example:

  • You might to go.

(This is NOT correct – we don’t use all of the infinitive – we need to remove the TO part)

So we say…

  • You might go. (This is correct)


  • She might knows.

(This IS NOT correct – we don’t conjugate the verb so no S is necessary – we need the base form of the infinitive)… so we say…

  • She might know. (This is correct)
