Mustn't vs. Don't have to

Added by Tomasz H. 13 January 2015 in category: English, Lexicon



It is prohibited, it is not allowed. It is important that you do not do something.


You mustn't drink that = It is forbidden to drink that

You mustn't tell him = Do not tell him, you are not allowed to tell him


Don't have to


There is no obligation, you are not required to do something (if you don't want it).


You don't have to drink that = You can drink that if you want, but it' not obligatory

You don't have to tell him = You can tell him, but it's not necessary.
