+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+.
+An Irregular Verb is one that does not form its past tense and past participle by adding ed to the present+.
+An Adverb is a word used to modify a verb, an adjective, or an adverb. [Footnote: Adverbs have several exceptional uses. They may be used independently; as, Now, there must be an error here. They may modify a phrase or a preposition; as, He came just in time; It went far beyond the mark. They may modify a clause or a sentence; as, He let go simply because he was exhausted; Certainly you may go.
It may also be noted here that adverbs are used interrogatively; as, How, when, and where is this to be done? and that they may add to the office of the adverb that of the conjunction; as, I go where I am sent.]
