Modal Verbs for Obligation and Advice
Modal verbs are special verbs that express necessity, obligation, advice, or permission. They are followed by the base form of the verb.
Must and Have to (Obligation)
Must: strong obligation from the speaker. ‘You must wear a seatbelt.’ (It’s the law/I say so). Have to: external obligation. ‘I have to wear a uniform at school.’ (It’s a rule). Past: ‘had to’. ‘I had to stay at home yesterday.’
Mustn’t vs Don’t have to
Mustn’t: prohibition (it’s forbidden). ‘You mustn’t smoke in hospital.’ Don’t have to: no obligation (it’s not necessary). ‘You don’t have to come if you don’t want to.’
Should and Ought to (Advice)
Should / ought to = it’s a good idea. ‘You should see a doctor.’ ‘You ought to study more.’ They are less strong than ‘must’.
