Definition of modal auxiliary
- : an auxiliary verb (such as can, must, might, may) that is characteristically used with a verb of predication and expresses a modal modification and that in English differs formally from other verbs in lacking -s and -ing forms
What is a modal verb?
A small group of auxiliary verbs, called the modal verbs (or modal auxiliary verbs, modal auxiliaries, or simply modals) are only used in combination with ordinary verbs. A modal verb changes the other verb’s meaning to something different from simple fact. Modals may express permission, ability, prediction, possibility, or necessity.
The principal modal verbs are: can, could, may, might, must, ought, shall, should, will, and would.
The modal verbs are different from ordinary verbs in several ways: 1) they have no inflections at all; that is, they lack an -ing form, an -ed form, and even an -s form for the third-person singular; 2) a modal verb is always followed by the infinitive form of a verb (unless that verb has already been stated) but never follows another verb; 3) modal verbs do not follow to and are not followed by to. (Ought to, like the near-modal verb have to, is a special case.)
In their simple form, modal verbs normally refer to present or future time:
I must be nearly there by now.
I might arrive a bit later than I’d anticipated.
A trip like this can take hours more than one expects.
As if English wasn’t hard enough to learn, modal verbs complicate things even further. There are a lot of irregularities in the English language that can be confusing to students learning it as a second to their native tongue. We don’t have genders like a lot of languages, instead we stick with “a” or “the”; we have 12 tenses most of which are never used; and we have so many similar words that often get mixed up like accept/except, bear/bare, and their/there. English and other Germanic languages, however, utilize modal verbs to help express a function and are vital to gaining command of the English language.

What are Modal Verbs?
Modal verbs are used in conjunction with verbs to express their function. Examples are permission, obligation, lack of necessity, possibility, ability, prohibition, advice and probability. You must remember that modal verbs are followed by an infinitive but without the word “to”. Must in the last sentence is an example of a modal verb. Modal verbs are different from other auxiliary verbs as they cannot stand alone in a sentence. They should always be followed by the base verb word (infinitive) like, play, work, run, and eat. Conjugated verbs such as: likes, played, working, ran and eats do not work with modal verbs. For a true beginner student of English this elementary English course will teach you the basic concepts, grammar, numbers and the alphabet.
