feel (v.)youdaoicibaDictYouDict[feel 词源字典]
Old English felan "to touch or have a sensory experience of; perceive, sense (something)," in late Old English "have a mental perception," from Proto-Germanic *foljan (cognates: Old Saxon gifolian, Old Frisian fela, Dutch voelen, Old High German vuolen, German fühlen "to feel," Old Norse falma "to grope"), from PIE root *pal- "to touch, feel, shake, strike softly" (cognates: Greek psallein "to pluck (the harp)," Latin palpare "to touch softly, stroke," palpitare "to move quickly"), perhaps ultimately imitative.

The meaning in Old English was "to perceive through senses which are not referred to any special organ."

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.)youdaoicibaDictYouDict
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.)youdaoicibaDictYouDict
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).

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].
