Modal Verbs

Modals in fact belong to verbs or auxiliary verbs though they do not do any action. Modals, in plain words, are words that indicate the intensity of command, request, permission, sense of obligation, etc.

The most common modals are can, could, may, might, should, would, must, ought to, dare, need.

Below is a classification of situations under which we use a modal. Study carefully.

Request – May (100%), Could (60%), Can (10%)
  • May I enter the class? (Between servant and his master. High respect)
  • Could I have a glass of water, please? (Between two strangers. Medium respect)
  • Can I use your pen? (Between friends. No respect but friendship)

In the three instances above you can see three people making three requests to three different people. While may is an expression of high respect and awe, could is less and can is more like a friendly gesture.
