Modals Exercises

Modal verbs play an important role in English grammar as they help express possibility, probability, ability, permission, necessity, and obligation. Verbs such as will, would, shall, should, can, could, may, might, must, need, and ought to are commonly used as helping verbs to support the main verb in a sentence. Understanding how these modals function is essential for forming meaningful and grammatically correct sentences. Modals Exercises provide learners with structured practice to identify, choose, and use modal verbs correctly in different contexts, thereby strengthening their overall command of the English language.
