We often use can to ask for and give permission.

Can I sit here?
You can use my car if you like.
Can I make a suggestion?

We also use could to ask for permission (but not to give it). Could is more formal and polite than can.


Could I ask you something?
Could I interrupt?
Could I borrow your pen for a moment, please?


Prohibition:

We use can't and mustn't to show that something is prohibited – it is not allowed.

We use can't to talk about something that is against the rules, particularly when we didn't make the rules.


What does this sign say? Oh, we can't park here.

Obligation:

We use have to and must to express obligation. There is a slight difference between the way we use them.


have to:

Have to shows us that the obligation comes from outside the speaker. 

We have to wear a uniform when we're working in reception.

Al has to work tomorrow so he can't come.


We sometimes call this 'external obligation'.


No obligation:

We use don’t have to to show that there is no obligation. You can do something if you want to but it's not compulsory.
