Modal verbs: may, might, can't

Modal verbs are a category of auxiliary verbs used to express ability, possibility, necessity, permission, and other related meanings. Here's how the modal verbs "may", "might", and "can't" are commonly used:

May:

1. "May" is used to express permission, possibility, or uncertainty.

   Examples:

   May I borrow your pen? (asking for permission)

   It may rain later today. (expressing a possibility)

   She may come to the party. (expressing uncertainty)

Might:

1. "Might" is also used to express possibility or uncertainty, but it is slightly less certain than "may".

   Examples:

   He might be busy. (expressing a possibility)

   We might go to the beach tomorrow. (expressing uncertainty)

Can't:

1. "Can't" is used to express impossibility or strong certainty that something is not possible.

   Examples:

   I can't swim. (expressing inability)

   It can't be true! (expressing disbelief or strong certainty)

It's important to note that modal verbs do not have an "-s" form for the third-person singular. Also, the base form of the main verb (infinitive without "to") follows modal verbs.

Examples of using modal verbs in sentences:

She may arrive late for the meeting.

They might not be able to attend the concert.

I can't understand this complicated math problem.

May I use your phone to make a call?

He might come to the party if he finishes his work.

Modal verbs add shades of meaning to sentences and are crucial for expressing various attitudes and possibilities in English. Practice using modal verbs in different contexts to become more comfortable with their usage.
