A verb is a word that describes an action, occurrence, or state of being in a sentence. Verbs are the main part of a sentence or phrase, along with nouns. Almost every sentence requires a verb. Verbs can be expressed in different tenses, depending on when the action is being performed. For example, "Jennifer walked to the store" is a sentence where "walked" is the verb that shows an action in the past tense. Verbs can also indicate the perfect tense and past participle. Verbs are essential in communication and are used to convey meaning in a sentence.
