Personal and impersonal obligation, absence of obligation, and weak obligation

We use ‘must’, ‘have to’, and ‘should’ to communicate obligation. There are important lessons in the difference in form between ‘must’ and the non-modal ‘have to’. The difference in meaning between these verbs varies according to whether the verb is positive, negative or interrogative.
