Might / May: Talking About Possibility

Might / May: Talking About Possibility

We use might and may when something is possible, but we are not sure. We use them for now or for the future.

Structure

• Positive: Subject + might/may + base verb. Example: It might rain later.
• Negative: Subject + might not / may not + base verb. Example: She may not come tonight.
• Question: We do not usually ask about possibility with may or might. We ask Do you think it will rain? or Is it possible that he is late? Short answers: It might. or Maybe.
• We do not add -s, and we do not use 'to' after might/may, like other modal verbs. Example: He might come.

How the Grammar Works

1. Use might or may when you are not sure. It is a guess, not a fact. Example: I might visit my parents this weekend.
2. Use them for now or for the future. Example: They might be at home now. Example: We may go out tomorrow.
3. The negative forms are might not and may not. We do not usually say mightn't or mayn't. Example: We might not finish the project on time.
4. You can also use maybe or perhaps at the start of a sentence. The meaning is the same. Example: Maybe she is busy.

Common Use Cases

• Guessing about the future: We might go to the beach tomorrow.
• Saying something is possible right now: He might still be at work.
• Saying something is possible, but not planned: I may need to leave early.

May vs Might: What's the Difference?

May and might mean almost the same. In everyday English, people use both. May can sound a little more formal. Some people think may is a little stronger, but there is no strict rule. Both are correct. Example: It may rain tomorrow. Example: It might rain tomorrow.

Frequent Mistakes and How to Avoid Them

• Adding 'to' after might/may. Wrong: It might to rain. Correct: It might rain. After a modal verb, we use the base verb.
• Adding -s with he, she or it. Wrong: It mights rain. Correct: It might rain. Modal verbs do not change.
• Mixing up might and must. He must be tired means I am almost sure. He might be tired means it is only possible.
• Mixing up possibility and permission. May I leave? asks for permission. I may leave means leaving is possible.

Comparison with Related Grammar

Might and may show less certainty than will, must and should. It will rain means I am sure. The bus should be here soon means I expect it. It might rain means it is only possible. Use might or may when you do not know what will happen.

Example Sentences

• I might visit my parents this weekend.
• It may rain this afternoon.
• She may not answer because she's usually busy at this time.
• They might be stuck in traffic.
• He might still be at work.
• We might not finish the project on time.

When to Use This Rule

Use might or may for guesses about now or later. Use will when you are sure.
