Synonym: To give up, yield, forego, cede, surrender, resign, abdicate, quit, relinquish, renounce, desert, forsake, leave, retire, withdraw from. To Abandon, Desert, Forsake. These words agree in representing a person as giving up or leaving some object, but differ as to the mode of doing it. The distinctive sense of abandon is that of giving up a thing absolutely and finally; as, to abandon one's friends, places, opinions, good or evil habits, a hopeless enterprise, a shipwrecked vessel. Abandon is more widely applicable than forsake or desert. The Latin original of desert appears to have been originally applied to the case of deserters from military service. Hence, the verb, when used of persons in the active voice, has usually or always a bad sense, implying some breach of fidelity, honor, etc, the leaving of something which the person should rightfully stand by and support; as, to desert one's colours, to desert one's post, to desert one's principles or duty. When used in the passive, the sense is not necessarily bad; as, the fields were deserted, a deserted village, deserted halls. Forsake implies the breaking off of previous habit, association, personal connection, or that the thing left had been familiar or frequented; as, to forsake old friends, to forsake the paths of rectitude, the blood forsook his cheeks. It may be used either in a good or in a bad sense. Origin: OF. Abandoner, F.abandonner; a (L. Ad)+bandon permission, authority, LL. Bandum, bannum, public proclamation, interdiction, bannire to proclaim, summon: of Germanic origin; cf. Goth. Bandwjan to show by signs, to designate OHG. Banproclamation. The word meant to proclaim, put under a ban, put under control; hence, as in OE, to compel, subject, or to leave in the control of another, and hence, to give up. See Ban.

| abandoned | 1. Forsaken, deserted. "Your abandoned streams." 2. Self-abandoned, or given up to vice; extremely wicked, or sinning without restraint; irreclaimably wicked; as, an abandoned villain. Synonym: Profligate, dissolute, corrupt, vicious, depraved, reprobate, wicked, unprincipled, graceless, vile. Abandoned, Profligate, Reprobate. These adjectives agree in expressing the idea of great personal depravity. Profligate has reference to open and shameless immoralities, either in private life or political conduct; as, a profligate court, a profligate ministry. Abandoned is stronger, and has reference to the searing of conscience and hardening of heart produced by a man's giving himself wholly up to iniquity; as, a man of abandoned character. Reprobate describes the condition of one who has become insensible to reproof, and who is morally abandoned and lost beyond hope of recovery. " God gave them over to a reprobate mind." (Rom. I. 28) Source: Websters Dictionary (01 Mar 1998) |
