Question

who many types of modals?​

Answer 1

Answer:

There are nine modal auxiliary verbs: shall, should, can, could, will, would, may, must, might. There are also quasi-modal auxiliary verbs: ought to, need to, has to. Why only quasi? Because the nine modals sit before the base form: I shall go, I could go, etc., but with ought/need/has we have to insert a to: I ought to go, it needs to be done, it has to be April (said at the onset of a shower, prompting inference).
