OBLIGATION AND NECESSITY: MUST AND HAVE TO
Must and have to have a very similar meaning.
Have to is more common for general, external obligations, for example rules and law. I have to wear a shirt and tie at work (it’s the rule in this company). Do you have to work on Saturday?
Must is more common for specific (i.e. on one occasion) or personal obligation. I must remember to phone Emily tonight, it’s her birthday. You must be on time for class tomorrow. There‘s a test.
You can also use have to and must for strong suggestions. You have to/must see that film, it’s fantastic.

You can often use can’t or not allowed to instead of mustn’t. You mustn’t park here. You can’t park here. You’ re not allowed to park here.
You can also use ought to and ought not to instead should and shouldn’t. You should take an umbrella with you. You ought to take an umbrella with you.
