Hello,everyone!
A modal verb is a type of verb that is used to indicate modality – that is: likelihood, ability, permission, request, capacity, suggestions, order, obligation, or advice. English modal verbs include must, shall, will, should, would, can, could, may, and might. In English, modal verbs are used to show different meanings and today, we are going to study some of them:

We can use ‘mustn’t’ to show that something is prohibited – it is not allowed.
We can choose ‘Must/have to-has to’ to talk about obligations.

‘Don’t have to and doesn’t have to ‘ are useful modal verbs in order to give the meaning of ‘lack of necessity’
