Every complete sentence needs a verb. Think of it as the engine. Without it, the sentence doesn't go anywhere. Verbs are the words that show what's happening or what is.

They provide the action or describe a state of being. If a noun is a person, place, or thing, the verb is what that person, place, or thing is doing or feeling.

The most common type of verb is an action verb. These are probably the ones you think of first. They describe a physical or mental action. If you can do it, it's likely an action verb.

In each of these sentences, the verb tells you what the subject is doing. The action can be obvious, like running or jumping, or it can be more subtle, like hoping or believing.

Not all verbs show action. Some verbs connect the subject of the sentence to more information about it. These are called linking verbs. They don't describe what the subject does, but what the subject is.

The most common linking verb is "to be" and its various forms: am, is, are, was, were. Other linking verbs include seem, become, feel, appear, and look.

In these examples, the verb links the subject (cat, soup, I) to a word that describes it (fluffy, delicious, student). No action is happening. The verb simply acts as a bridge.

Sometimes, a verb needs a little help to express its full meaning. That's where helping verbs, also known as auxiliary verbs, come in. They team up with a main verb to create a verb phrase.

Common helping verbs include forms of "to be" (is, are, was), "to have" (has, have, had), and "to do" (do, does, did). Others like will, can, should, and may also act as helpers.

Notice how the helping verb works with the main verb (running, finished, go) to clarify the action. On their own, helping verbs don't show the main action, but they are essential for giving the main verb more context.

Understanding these three types of verbs is the first step to building strong, clear sentences.
