Modal verbs are a special kind of verb. They always ‘come with’ another verb, for example:
– You must go now. See how we have ‘must’ and ‘go’. Go is the main verb.
– Can you fly? No, I can’t. In the second sentence, ‘I can’t’ means ‘I can’t fly’; fly is the main verb.
The modal verb changes the meaning of the sentence. So in the first sentence, ‘You must go’ makes the action of ‘going’ into a more important action! ‘Can you fly?’ doesn’t mean the same as ‘are you flying now’ – it’s about your ability to fly, some time.
Here is a list of modal verbs (and some verbs which are like modals – we can call them semimodals):
must / mustn’t / should / shouldn’t / may / may not / have to / don’t have to
Can you put these words in order, from 100% to 0% where 100% is something you MUST do?
100% ———————————————————- 0%
Do you know the meaning of ‘need to’ and ‘ought to’? These are semimodals too and have their own meanings.
