conscience (n.): early 13c., from Old French conscience "conscience, innermost thoughts, desires, intentions; feelings" (12c.), from Latin conscientia "knowledge within oneself, sense of right, a moral sense," from conscientem (nominative consciens), present participle of conscire "be (mutually) aware," from com- "with," or "thoroughly" (see com-) + scire "to know" (see science).

Probably a loan-translation of Greek syneidesis, literally "with-knowledge." Sometimes nativized in Old English/Middle English as inwit. Russian also uses a loan-translation, so-vest, "conscience," literally "with-knowledge."
fine (adj.): mid-13c., "unblemished, refined, pure, free of impurities," also "of high quality, choice," from Old French fin "perfected, of highest quality" (12c.), a back-formation from finire or else from Latin finis "that which divides, a boundary, limit, border, end" (see finish (v.)); hence "acme, peak, height," as in finis boni "the highest good." The English word is from c. 1300 as "rich, valuable, costly;" also in a moral sense "true, genuine; faithful, constant." From late 14c. as "expertly fashioned, well or skillfully made," also, of cloth, "delicately wrought." Of weapons or edges, "sharp" from c. 1400. In reference to quality of gold and silver, late 15c.

In French, the main meaning remains "delicate, intricately skillful;" in English since c. 1300 fine has been also a general broad expression of admiration or approval, the equivalent of French beau (as in fine arts, 1767, translating French beaux-arts). Related: Finer; finest. Fine print is from 1861 as "type small and close-set;" by 1934 in the extended sense "qualifications and limitations of a deal."
gross (adj.): mid-14c., "large;" early 15c., "thick," also "coarse, plain, simple," from Old French gros "big, thick, fat; tall; strong, powerful; pregnant; coarse, rude, awkward; ominous, important; arrogant" (11c.), from Late Latin grossus "thick, coarse" (of food or mind), in Medieval Latin "great, big" (source also of Spanish grueso, Italian grosso), a word of obscure origin, not in classical Latin. Said to be unrelated to Latin crassus, which meant the same thing, or to German gross "large," but said by Klein to be cognate with Old Irish bres, Middle Irish bras "big."

Its meaning forked in English. Via the notion of "coarse in texture or quality" came the senses "not sensitive, dull stupid" (1520s), "vulgar, coarse in a moral sense" (1530s). Via notion of "general, not in detail" came the sense "entire, total, whole, without deductions" (early 15c.), as in gross national product (1947). Meaning "glaring, flagrant, monstrous" is from 1580s; modern meaning "disgusting" is first recorded 1958 in U.S. student slang, from earlier use as an intensifier of unpleasant things (gross stupidity, etc.).
incorruptible (adj.): mid-14c., in a physical sense, from Middle French incorruptible (14c.), or directly from Late Latin incorruptibilis, from in- ânotâ (see in- (1)) + corruptibilis (see corruptible). From 1660s in a moral sense. Related: Incorruptibly.
unblemished (adj.): c. 1300, from un- (1) "not" + past participle of blemish (v.). Originally in moral sense; material sense is attested from mid-15c.
untainted (adj.): 1580s, in the moral sense; c. 1600 in the physical sense; from un- (1) "not" + past participle of taint (v.). Earlier was untained (mid-15c.), from a Middle English variant of taint (v.).
vice (n.1): "moral fault, wickedness," c. 1300, from Old French vice "fault, failing, defect, irregularity, misdemeanor" (12c.), from Latin vitium "defect, offense, blemish, imperfection," in both physical and moral senses (in Medieval Latin also vicium; source also of Italian vezzo "usage, entertainment"), from PIE *wi-tio-, from root *wei- (3) "vice, fault, guilt."
Horace and Aristotle have already spoken to us about the virtues of their forefathers and the vices of their own times, and through the centuries, authors have talked the same way. If all this were true, we would be bears today. [Montesquieu]
Vice squad "special police unit targeting prostitution, narcotics, gambling, etc.," is attested from 1905, American English. Vice anglais "fetish for corporal punishment," literally "the English vice," is attested from 1942, from French. In Old French, the seven deadly sins were les set vices.
