What is a Modal Auxiliary? 

Modal auxiliaries are auxiliary verbs that lend different shades of meaning to the main verb to which they are attached. 

Modal help to express the mood or attitude of the speaker and convey ideas about the possibility, probability, obligation, advisability, and permission. 

The single-word modal auxiliaries are: Can, May, Must, Shall, Will, Could, Might, Should, Would.

Example:
