Frequently asked questions

What is the main difference between have to and must?

For A2, remember that have to often describes obligations from external rules or situations (e.g., I have to wear a uniform). Must can be used for strong personal obligations (e.g., I must call my mother) or for strong recommendations.

Can I use got to instead of have to?

Yes, in informal spoken English, got to (often shortened to gotta) is common. For example, I’ve got to go now means the same as I have to go now. However, have to is better for formal writing.

Does don’t have to mean the same as must not?

No, they are very different! Don’t have to means “it is not necessary” (e.g., You don’t have to pay). Must not means “it is forbidden” or “it is not allowed” (e.g., You must not smoke here).
