2、fine:  Both the adjective and the noun fine have come a very long way since their beginnings in Latin finis ‘end’. The etymological sense of the adjective is ‘finished’ – hence, ‘of high quality’. It comes via Old French fin from Vulgar Latin *fīnus, an adjective formed from the Latin verb fīnīre ‘limit, complete’ (source of English finish). (A derivative of *finus was the noun *finitia, from which ultimately English gets finesse .) The noun fine also comes from an Old French fin, this time a noun descended directly from Latin fīnis.In medieval times this was used for ‘money to be paid at the completion of legal proceedings’ – hence the present-day sense ‘payment imposed as a punishment’. From the same ultimate source, but reflecting different aspects of it, come confine  and define  (‘limitation’) and refine  (‘high quality’).=> confine, define, final, finance, finesse, finish, refine
4、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."
6、c. 1200,"termination, end; end of life,"from Old French fin"end, limit, boundary; death; fee, payment, finance, money"(10c.), from Latin finis"end"(see finish (v.)), in Medieval Latin also"payment in settlement, fine or tax." Modern meaning"exaction of money payment for an offense or dereliction"is via sense of"sum of money paid for exemption from punishment or to compensate for injury"(mid-14c., from the same sense in Anglo-French, late 13c.) and from phrases such as to make fine"make one's peace, settle a matter"(c. 1300). Meaning"sum of money imposed as penalty for some offense"is first recorded 1520s.
