MODAL VERBS

A modal is a type of auxiliary (helping) verb that is used to express: ability, possibility, permission or obligation. Modal phrases (or semi-modals) are used to express the same things as modals, but are a combination of auxiliary verbs and the preposition to. The modals and semi-modals in English are:
1. Should- shouldn't
2. Have to- haven't
3. Must - musn't
4. Can- can't
Forms:

Should + subject + base form of the verb


must / have to / need to + base form of the verb

Examples:

  • She can speak six languages.
  • can't drive.
  • Children must do their homework.
  • We have to wear a uniform at work.
  • You should stop smoking.
