As well as making simple statements or asking questions, we may sometimes want to express our intentions and attitudes, talk about necessity and possibility, or make offers, requests, or suggestions. In English, these uses of language are usually expressed by a set of verbs called modals. Modals always occur with other verbs, and can be thought of as a special kind of auxiliary verb, e.g.
I must go to the post office.
Can I borrow your umbrella?
The most commonly used modals in English are:
can / could / will / would / may / might / must / ought to / should
