DEFINITIONS.
CLASSES OF VERBS WITH RESPECT TO MEANING.
+A Transitive Verb is one that requires an object+. [Footnote: The object of a transitive verb, that is, the name of the receiver of the action, may be the object complement, or it may be the subject; as, Brutus stabbed Caesar, Caesar was stabbed by Brutus.]
+An Intransitive Verb is one that does not require an object+.
CLASSES OF VERBS WITH RESPECT TO FORM.
+A Regular Verb is one that forms its past tense and past participle by adding ed to the present+. [Footnote: If the present ends in e, the e is dropped when ed is added; as, lov_e_, lov_ed_; believ_e_, believ_ed_.]
+An Irregular Verb is one that does not form its past tense and past participle by adding ed to the present+.
