Modal Verbs Exercises

Modal verbs are helping verbs used with the base form of a main verb to express ability, possibility, permission, necessity, advice, or logical deduction. They show the speaker’s attitude or judgment about a situation.

Modal verbs do not change according to the subject and are always followed by the base form of the verb (without -s, -ed, or -ing).
