what are modals pls explain
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:
- Can/could/be able to
- May/might
- Shall/should
- Must/have to
- Will/would
