MODALS OF POSSIBILITY AND PROBABILITY
(may, might, could, must, can’t)

We use modal verbs in combination with main verbs: modal + verb (base form).

Must is used to show that we are certain.

Wow, you are really sweaty. It must be hot outside.

Can’t is used to show something is impossible.

We can’t give him the job because he doesn’t have enough experience.

May, might, and could are used to talk about present or future possibilities. They can be used to explore possible options for the future, to make suggestions in order to solve a problem, or to guess about a situation when we don’t have all the facts.

After I finish university I may go abroad or I may try to get a job right away.

Your car might be having problems because the battery is too old.

The remote control could be in the couch.

May not and might not can be used to show that present or future possibilities are not likely. But could not cannot be used in this way.

They might not go on vacation this year.
