Modal Verbs with Simple Definitions and Usage Examples

Modal verbs are an essential part of English grammar, serving as auxiliary verbs that express necessity, possibility, ability, or permission. They help convey the attitude of the speaker towards the action being discussed. Common modal verbs include can, could, may, might, must, and shall. When someone says, “I can swim,” they indicate their ability to do so; conversely, if they say, “I may go to the party,” it expresses a possibility rather than certainty. Understanding how to use these verbs effectively is crucial for mastering English grammar and enhancing communication skills.

What Are Modal Verbs?

Modal verbs are a fascinating aspect of English grammar that often goes unnoticed in everyday communication. These auxiliary verbs, which include can, could, may, might, must, and should, serve a unique purpose in conveying necessity, possibility, ability, and permission. For example, when I say “I can swim,” I’m expressing my ability to do something; whereas if I say “You must finish your homework,” I’m indicating an obligation. This subtle yet powerful function of modal verbs adds nuance to our language and enables us to express complex ideas efficiently.
