[caffeine etymology, caffeine origin, 英语词源]
feign: feign: [13] Feign is first cousin to faint. It comes from the present stem of Old French faindre or feindre ‘pretend, shirk’, whose past participle gave English faint. This in turn came from Latin fingere ‘make, shape’, which also gave English effigy, fiction, figure, and figment and is related to English dairy and dough. The semantic progression from ‘make, shape’ to ‘reform or change fraudulently’, and hence ‘pretend’, had already begun in classical Latin times.
=> dairy, dough, effigy, faint, fiction, figure
feint: feint: The noun feint [17] and the adjective feint [19] are essentially different words, but they have a common ultimate origin. Feint ‘misleading mock attack’ was borrowed from French feinte, a noun use of the feminine form of the past participle of feindre ‘pretend’ (from which English got feign). Feint ‘printed with pale lines’ is an artificial variant of faint introduced in the printing trade in the mid 19th century (and faint itself originally came from the past participle of feindre).
=> faint, feign
feisty: feisty: [19] Feisty, nowadays a colloquial Americanism for ‘quarrelsome’ or ‘spirited’, originated in Middle English as a term for a ‘farting dog’. It goes back to the now obsolete English verb fist ‘fart’, which came ultimately from Indo-European *pezd- (source also of Latin pēdere ‘break wind’, whence English petard ‘small bomb’ [16], as in ‘hoist with one’s own petard’); like *perd-, the Indo-European ancestor of English fart, this was probably of imitative origin.

In the 16th and 17th centuries the expression fisting dog, literally ‘farting dog’, was applied contemptuously to a ‘mongrel’ or ‘cur’. This eventually became shortened to feist, and (mongrels being notoriously combative) feisty was born.
=> fizzle, petard
forfeit: forfeit: [13] A forfeit was originally a ‘transgression’ or ‘misdemeanour’. The word comes from Old French forfet, a derivative of the verb forfaire or forsfaire ‘commit a crime’. This was a compound formed from fors- ‘beyond (what is permitted or legal)’, which is descended from Latin forīs ‘outdoor, outside’ (source of English forest and related to foreign), and faire ‘do, act’, which came from Latin facere (whence English fact, fashion, feature, etc).

The etymological meaning ‘misdeed’ was originally taken over from Old French into Middle English (‘Peter was in hand nummen [taken] for forfait he had done’, Cursor mundi 1300), but by the 15th century it was being edged out by ‘penalty imposed for committing such a misdeed’.
=> door, fact, factory, fashion, forest, foreign
caffeine (n.): trimethyl-derivative of xanthine, 1830, from German Kaffein, coined by chemist F.F. Runge (1795-1867), apparently from German Kaffee "coffee" (see coffee) + chemical suffix -ine (2) (German -in). The form of the English word may be via French caféine.
counterfeit (v.): late 13c., from Old French contrefait "imitated" (Modern French contrefait), past participle of contrefaire "imitate," from contre- "against" (see contra-) + faire "to make, to do" (from Latin facere; see factitious). Medieval Latin contrafactio meant "setting in opposition or contrast." Related: Counterfeited; counterfeiting. The noun and adjective are from late 14c.
decaffeinate (v.): 1909 (implied in decaffeinated), from de- + caffeine + -ate (2).
feign (v.): A 17c. respelling of fain, fein, from Middle English feinen, feynen "disguise or conceal (deceit, falsehood, one's real meaning); dissemble, make false pretenses, lie; pretend to be" (c. 1300), from Old French feindre "hesitate, falter; be indolent; lack courage; show weakness," also transitive, "to shape, fashion; depict, represent; feign, pretend; imitate" (12c.), from Latin fingere "to touch, handle; devise; fabricate, alter, change" (see fiction).

From late 14c. as "simulate (an action, an emotion, etc.)." Related: Feigned; feigning. The older spelling is that of faint, feint, but this word acquired a -g- in imitation of the French present participle stem feign- and the Latin verb.
feint (n.): 1670s, "a false show, assumed appearance;" 1680s as "a pretended blow, movement made to deceive an opponent as to the object of an attack," from French feinte "a feint, sham, fabrication, pretense," abstract noun from Old French feint "false, deceitful; sham, artificial; weak, faint, lazy, indolent" (13c.), originally fem. past participle of feindre "pretend, shirk" (see feign).

Borrowed c. 1300 as adjective ("deceitful," also "enfeebled; lacking in courage;" see feint (v.)), but long obsolete in that sense except as a trade spelling of faint among stationers and paper-makers. Also as a noun in Middle English with senses "false-heartedness" (early 14c.), "bodily weakness" (c. 1400).
feint (v.): c. 1300, feinten, "to deceive, pretend" (obsolete), also "become feeble or exhausted; to lack spirit or courage," from Middle English feint (adj.) "feigned, false, counterfeit" and directly from Old French feint "false, deceitful; weak, lazy," past participle of feindre "to hesitate, falter; lack courage; feign, pretend, simulate" (see feign). Sense of "make a sham attack, make a pretended blow" is attested by 1833, from the noun (1680s as "a feigned attack"). Related: Feinted; feinting.
feist (n.): also fist, "a breaking wind, foul smell, fart," mid-15c. (Old English had present participle fisting, glossing Latin festiculatio), a general West Germanic word with cognates in Middle Dutch veest, Dutch vijst; see feisty.
feisty (adj.): 1896, "aggressive, exuberant, touchy," American English, with -y (2) + feist "small dog," earlier fice, fist (American English, 1805); short for fysting curre "stinking cur," attested from 1520s, with present participle of now-obsolete Middle English fysten, fisten "break wind" (mid-15c.), from Proto-Germanic *fistiz "a fart," said to be from PIE *pezd- (see fart), but there are difficulties.

The 1811 slang dictionary defines fice as "a small windy escape backwards, more obvious to the nose than ears; frequently by old ladies charged on their lap-dogs." Compare also Danish fise "to blow, to fart," and obsolete English aske-fise, "fire-tender," literally "ash-blower" (early 15c.), from an unrecorded Norse source, used in Middle English for a kind of bellows, but originally "a term of reproach among northern nations for an unwarlike fellow who stayed at home in the chimney corner" [OED].
forfeit (n.): late 14c., forfet, "misdeed, offense against established authority," also "something to which the right is lost through a misdeed," from Old French forfet, forfait "crime, punishable offense" (12c.), originally past participle of forfaire "transgress," from for- "outside, beyond" (from Latin foris; see foreign) + faire "to do" (from Latin facere; see factitious). A French version of Medieval Latin foris factum; the notion perhaps is to "do too much, go beyond (what is right)." As an adjective from late 14c., from Old French forfait. Compare foreclose.
forfeit (v.): mid-14c., " transgress, offend, misbehave;" late 14c., "to lose by misconduct," from forfeit (n.) or from Anglo-French forfet, Old French forfait, past participle of forfaire. Related: Forfeited; forfeits; forfeiting.
forfeiture (n.): mid-14c., "loss of property as punishment for a crime, debt, etc.," from Old French forfaiture "crime, transgression; penalty for committing a crime" (12c.), from forfait (see forfeit (n.)).
Sinn Fein (n.): 1905, from Irish, literally "we ourselves," from Old Irish féin "self," from PIE *swei-no-, suffixed form of root *s(w)e- (see idiom). Movement founded 1905 by Irish journalist and politician Arthur Griffith (1872-1922).
surfeit (v.): late 14c., intransitive, "indulge or feed to excess," from surfeit (n.). Related: Surfeited; surfeiting. Transitive sense from 1590s.
surfeit (n.): early 14c., "excess quantity;" late 14c., "overindulgence," from Old French sorfet "excess; arrogance" (Modern French surfait), noun use of past participle of surfaire "overdo," from sur- "over" (see sur- (1)) + faire "do," from Latin facere "to make, do" (see factitious).
unfeigned (adj.): late 14c., "sincere, genuine, true, real," from un- (1) "not" + past participle of feign (v.).
