Let’s remember the uses for MAY and MIGHT (4ºESO)…
MAY:
1. We can use ‘may’ to ask for permission. However this is rather formal and not used very often in modern spoken English
Ex: May I borrow your pen?
May we think about it?
May I go now?
2. We use ‘may’ to suggest something is possible.
Ex: It may rain later today.
I may not have time to do it today.
Pete may come with us
MIGHT:
1. We use ‘might’ to suggest a small possibility of something. Often we read that ‘might’ suggests a smaller possibility that ‘may’, there is in fact little difference and ‘might is more usual than ‘may’ in spoken English.
Ex: She might be at home by now but it’s not sure at all.
It might rain this afternoon.
I might not have time to go to the shops for you.
I might not go.
2. For the past, we use ‘might have’.
Ex: He might have tried to call while I was out.
I might have dropped it in the street.
