 Usage: -- To Affirm, Asseverate, Aver, Protest.  We affirm when we declare a thing as a fact or a proposition. We asseverate it in a peculiarly earnest manner, or with increased positiveness as what can not be disputed. We aver it, or formally declare it to be true, when we have positive knowledge of it. We protest in a more public manner and with the energy of perfect sincerity. People asseverate in order to produce a conviction of their veracity; they aver when they are peculiarly desirous to be believed; they protest when they wish to free themselves from imputations, or to produce a conviction of their innocence.

 To thee, who hast thy dwelling here on earth.   --Milton.
