Verbs express actions, states of being, or conditions. There are several types of verbs including action verbs, linking verbs, helping verbs, and verbs that indicate tense such as present, past, or future. Action verbs show physical or mental actions, while linking verbs connect subjects to predicates by expressing a state of being. Helping verbs help express shades of meaning along with a main verb. Verbs can also be transitive or intransitive, with transitive verbs taking direct objects and intransitive verbs not.
