The Modal Verbs May and Might
You’ve probably already studied some modal verbs in English, like ‘can’ and ‘must’. Perhaps you’ve heard about ‘may’ and ‘might’ and not been sure about what they mean and when they’re used. So here’s your chance to find out more about these two important modal verbs, then you can practice using them yourself.
What is a modal verb?
A modal verb is a verb that is used in combination with a normal verb. While auxiliary verbs help make questions and negatives and put a verb in a particular tense, modal verbs add a special meaning. For example, the phrase “They go to school” can change meaning with a modal verb in the following ways:
They must go to school. = They have an obligation to go.
They can go to school. = They have the possibility to go.
They might go to school. = It’s possible they will go to school.
Modal verbs can express obligation, advice, permission, offers, the future, and possibility.
What do all modal verbs have in common?
The convenient thing about modal verbs is that they all have some key things in common:
- Modal verbs don’t add -s for the third person singular, so the form is always the same. For example, She can swim.
- The question form is created by inverting the subject and the verb. For example, Will you go?
- We make the negative form by adding ‘not’. For example, They couldn’t attend the meeting.
- They are followed by the verb without ‘to’. For example, We might watch a movie.
- They don’t have an infinitive form. When necessary we use another word. For example, She would like to be allowed to arrive ten minutes late.
These similarities can really help you when you speak because you don’t have to worry about different forms or rules. The only modal verb that doesn’t follow these rules is ‘have to’, which acts like a normal verb.
May and Might
May and might are modal verbs that can have a similar meaning. They can be used to describe two ideas:
- Possibility (in the past, present or future)
Possibility in the Present
We can use both may and might to express a possibility or make a prediction. For example,
Tom might win this game. He’s been playing very well recently.
We may go out later. I’m not sure.
Do you think the company might hire more people next year?
There is a small difference in the level of probability. May usually expresses a 50% possibility, while an action with might normally means a slightly lower possibility, e.g. 40%. For example,
It may rain later on. We’d better take an umbrella. (50% probable)
It might rain later on, but I don’t think it will. (40% probable)
Might is also a bit more informal than may and is more common in spoken English.
Possibility in the Past
We can also may and might to express possibility in the past. In this case we had have + past participle of the verb. For example,
Where’s my wallet? – You might have left it in your jacket.
Mr Hunt is late. He may have missed his train.
Ann may have failed the exam because she was sick.
Marco wasn’t at the party. – He might not have wanted to come.
When we ask and give permission we often use may as an alternative to can. For example,
May I come in?
May we sit here? – Yes, you may.
May I leave early Sir? – No, you may not.
In the past, might was also used to make requests. For example, Might we come in? But it’s quite unusual today and only used in a really formal context.
We generally use may for requests in the first person – I and we. With you it’s more common and natural to use Could. For example,
Could you help me, please?
Other uses of May and Might
We can also use these modal verbs in the following situations:
- MAY to express a wish. For example, May you both live happily ever after together.
- MAY or MIGHT in combination with ‘as well’ to mean you should do something because there’s no better alternative. For example, The cinema is close. We might as well walk.
May and might are clearly great modal verbs to know because they enable you to do several important things in English such as make predictions and ask permission.
