Definition of Modal Verb : Modal verbs are used to represent a variety of hypothetical situations, including requests, advise, and capacity (a complete list is provided in the following section). They are used in conjunction with a primary verb to subtly alter its meaning. They can't necessarily be used on their own because they are auxiliary verbs. (A modal verb should only be used by itself if the context makes it obvious what the primary verb is.)

Example : I swim every Tuesday.

I can swim every Tuesday.

The first sentence is just a statement. But the second one there is a modal verb Can.
