Some intransitive verbs have a causative meaning, and take an object: 1 run , I ran a pin into my finger. Intransitive verbs may take a noun of kindred meaning as object (called the cognate object); as, to sleep a sleep, to run a race, to live a life. Verbs used with the third person only are called impersonal verbs; as, methinks , it rains , it snows . In the case of some verbs, the transitive form is distinguished from the corresponding intransitive by a change of vowel; as, raise , rise; set , sit ; fell , fall . Such verbs are called causative (q. v.). The past tense of strong verbs is expre ed by a change of vowel only; as, throw , threw ; the past tense of weak verbs by adding to the verbal root the syllable -ed ; as, shout, shouted ; or its euphonic substituted ( -ed ); as love , loved . [STRONG, WEAK.] Auxiliary verbs are used in forming the tenses of other verbs; as, I have seen. [AUXILIARY.] "You have told me that a verb is (as every word also must be) a noun; but you added, that it is also something more; and that the title given on account of that distinguishing something more than the mere nouns convey."- Tooke: Diversions of Purley, pt. ii., ch. viii.
