Linking verbs: Verbs that do not show action; instead, the linking verb renames or describes the subject.
Action verbs: express action by describing the behavior of a person, place or thing. They may
describe physical or mental actions.Auxiliary verbs: which are sometimes called helping verbs, act as helpers to other verbs. They
appear in front of action verbs and linking verbs.A transitive verb always has a noun that receives the action of the verb.
