In this article we will discuss when and how to use Must / May / Might and Cannot in details.
- We use “Must” to express that we feel sure that something is true.
The football team is playing really good today, they must win.
They must be rich – look at their big house and beautiful car.
- We use “Cannot” to say we are sure that something is impossible.
I don`t believe you, it cannot be true.
He cannot be so ill, I saw him playing football yesterday.
- We use “May, Might, Could” to say that it is possible that something will happen in the future or something is possible to be true. There is no difference between “May” and “ Might”, so you can use them instead of each other in order not to repeat it always.

I am not sure whether I can lend you any money. I may not have enough.
- We can use “Could” instead of “may” or “might”. But with could the possibility is smaller.
