Modal verbs:
- Modals are helping verbs that add a mood or attitude to the main verb: ability, possibility, duty, advice, necessity.
- The modals are can, could, may, might, shall, should, will, would, must, and the semi-modals ought to, need and dare.
- Modals never take -s, -ed or -ing and are followed by the base form of the verb (ought takes "to").
- do / does / did are primary auxiliaries: they form questions, negatives and emphasis, but add no mood of their own.
Example: You ought to respect your elders.
(A) Ought — Modal.
- "Ought to" expresses duty or advice: You ought to help him.
(B) must — Modal.
- It expresses necessity or obligation: You must wear a helmet.
(C) does — Not a modal.
- It is a form of the auxiliary do (Does she sing?), or a main verb meaning "performs" (She does her work).
(D) should — Modal.
- It expresses advice or duty: You should sleep early.
(E) doesn't — Not a modal.
- It is the negative of the auxiliary does (He doesn't eat meat).
