Sometimes particles and participial adjectives formed with this;prefix coincide in form with compounds of the negative prefix un- (see;2d Un-); as in undone (from undo), meaning unfastened, ruined; and;undone (from 2d un- and done) meaning not done, not finished.

Those which have acquired an opposed or contrary, instead of;a merely negative, meaning; as, unfriendly, ungraceful, unpalatable,;unquiet, and the like; or else an intensive sense more than a prefixed;not would express; as, unending, unparalleled, undisciplined,;undoubted, unsafe, and the like.;adv. Those which have the value of independent words, inasmuch as;the simple words are either not used at all, or are rarely, or at least;much less frequently, used; as, unavoidable, unconscionable,;undeniable, unspeakable, unprecedented, unruly, and the like; or;inasmuch as they are used in a different sense from the usual meaning;of the primitive, or especially in one of the significations of the;latter; as, unaccountable, unalloyed, unbelieving, unpretending,;unreserved, and the like; or inasmuch as they are so frequently and;familiarly used that they are hardly felt to be of negative origin; as,;uncertain, uneven, and the like.;adv.
