This document discusses different types of verbs. It describes verbs as being classified into main verbs and helping verbs, action verbs and linking verbs, and transitive verbs and intransitive verbs. Main differences include:
- Helping verbs support the main verb. Verb phrases contain one main verb and zero or more helping verbs.
- Action verbs express physical or mental activity while linking verbs connect the subject to a describing word. Only action verbs can take direct objects.
- Transitive verbs have a direct object receiving the verb's action, while intransitive verbs do not take direct objects. Whether a verb is transitive or intransitive can depend on how it is used in a sentence.
