Modal verbs in English grammar express the ability, permission, obligation, possibility, etc. Modal verbs only have one form, meaning that they are used in simple present and don't have past simple and past participle forms.

However, some modal verbs can have alternative forms which can be used in different tenses.

Permission

Rule 1: We can use both may and might to ask permission in present simple. May and might are more polite than could.

Note: We usually only use may in questions with I and we.

Example

Explanation

May/Might I have a black coffee to go, please?

Both may and might are used to ask for permission, although might is a more formal and rarely used form of request.

Rule 2: We can only use may to give permission.

Example

Explanation

You may have your coffee here, as well.

May is used to give permission.

Possibility

Rule 3: We can use both may and might to express possibility in the future. There is no difference between may and might.

Note: We rather don't use contractions with may not and might not.

Example

Explanation

I may go to visit my parents this weekend.

May is used to show the possibility of an action in the future.

I might not see you tomorrow at the party.

Might not is used to show the possibility of not seeing someone in the future.

Deduction

Rule 4: We can use both may and might when we think something is most likely true, but we are not 100% sure.

Example

Explanation

She may/might not want to make career in marketing.

Both may and might not are used to talk about something perhaps true, but without complete confidence.

Rule 5: We can use may/might (not) + have + past participle to speculate about something.
