Modal verbs help the main verbs in the sentences.
Modal verbs have a job of their own to do.
In this lesson, you’ll learn when to use each modal verb and practise using them.
Can/Can’t
Do/does/don’t/doesn’t
Could
Must
Should
Would
A main verb should never change form after a modal verb. All verbs stay the same.
In this video, Claire explains the main verbs of ‘can’ and ‘do’ with examples.
