The document provides definitions and examples for different types of verbs: - Helping verbs are used before the main verb to convey additional information about the function of the main verb. Examples are can, may, must. - Linking verbs connect the subject to a noun or adjective that often renames or describes the subject, such as is, are, am, was, were. - Action verbs express actions and can be either transitive or intransitive. Transitive verbs exert an action on an object, while intransitive verbs make sense without an object.
