Must is a word that is used to talk about an obligation, something you have to do, like following a law or a rule. In this programme we look at how to use this word and its negative form, mustn't.
OBLIGATION AND NO CHOICE
HAVE TO
Have to and must are both used to express obligation. There is a slight difference between the way they are used.
Have to shows us that the obligation comes from somebody else. It’s a law or a rule and the speaker can’t change it.

- In Britain you have to buy a TV licence every year.
- I must call my dad tonight.
- You must hand in your homework on Tuesday or your mark will be zero.

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.
