MAY AND MIGHT
- They are modal verbs and they are uninflected: they are the same for all subjects.
- We usually use a contraction for may not and we rarely use mightn't.
- We don't generally use may and might to ask questions about the future. BUT we can use May I...? to ask for permission.
USE
To express future possibility.
Examples:
- I may / might visit my American relatives next summer.
- There's a chance that I'll visit my American relatives next summer.
To make predictions about the future.
Examples:
- There is a thunderstorm, so my flight may / might be late.
- It's possible that my flight will be late due to the thunderstorm.
We use may and might in first conditional sentences instead of will, to make the sentence less certain.
Examples:
- If it is sunny today, we may go to the lake.
(more certain)
- If it is sunny today, we might / might not go to the lake.
(less certain)
