A modal verb, also known as a modal auxiliary or simply a modal, is a type of auxiliary verb that is used to express various degrees of possibility, ability, permission, necessity, or obligation in a sentence. Modal verbs are unique in that they do not have a specific meaning on their own but instead modify the main verb in a sentence to convey a specific sense or attitude. Examples of modal verbs include "can," "could," "may," "might," "shall," "should," "will," "would," "must," "ought to," and "need to." These verbs are used to indicate different shades of meaning and can greatly impact the overall tone and intention of a sentence.
