Modals Exercises for Class 9 CBSE With Answers

What are the Modal Verbs?
Modals (also called modal verbs, modal auxiliary verbs, modal auxiliaries) are special verbs which behave irregularly in English. They are different from normal verbs like “work, play, visit…” They give additional information about the function of the main verb that follows it. They have a great variety of communicative functions.

Modals are verbs used to express the mood or attitude of the speaker. They are used before ordinary verbs and express meanings such as permission, possibility, certainty and necessity. Modals have not ‘-s/es’ in the third person singular. They have no infinitive and -ing form.
