There are three types of verbs that you can use in a sentence: action verbs, linking verbs, or
helping verbs.
Action Verbs: A verb that connects the subject to an action. An action verb answers the question what is the subject doing?
Ex: He gave a short speech before we ate.
Linking Verbs: A verb can often connect the subject of the sentence to a describing word.
Ex: The clock seemed broken.
Helping Verbs: Helping verbs are verbs that are used with the main verb to describe a mood or tense. Helping verbs are usually a form of be, do, or have.
Ex: We have seen that movie three times.
Tip:
Whenever you write or edit sentences, keep the subject and verb in mind. As you write, ask yourself these questions to keep yourself on track:
Subject: Who or what is the sentence about?
Verb: Which word shows an action or links the subject to a description?
