Nouns and Modals

Nouns are words that name people, places, things, or ideas—such as "teacher," "city," or "happiness." Modals are auxiliary verbs like "can," "may," "must," or "should" that express possibility, ability, permission, or obligation. They help modify the meaning of main verbs to convey different nuances or degrees of certainty. For example, "she can swim" indicates ability, while "you must leave" shows obligation. Together, nouns and modals help form clear and precise sentences by identifying what is involved and conveying the speaker's attitude or intent regarding actions or concepts.
