fetid (adj.)youdaoicibaDictYouDict
early 15c., from Latin fetidus (commonly, but incorrectly, foetidus) "stinking," from fetere "have a bad smell, stink." This is perhaps connected with fimus "dung," or with fumus "smoke."
fetish (n.)youdaoicibaDictYouDict
"material object regarded with awe as having mysterious powers or being the representative of a deity that may be worshipped through it," 1610s, fatisso, from Portuguese feitiço "charm, sorcery, allurement," noun use of an adjective meaning "artificial."

The Portuguese adjective is from Latin facticius "made by art, artificial," from facere "to make, do, produce, etc." (see factitious, and compare French factice "artificial," restored from Old French faitise, from Latin facticius). Via the French word, Middle English had fetis, fetice (adj.) "cleverly made, neat, elegant" (of things), "handsome, pretty, neat" (of persons). But in the Middle Ages the Romanic derivatives of the word took on magical senses; compare Portuguese feiticeria "sorcery, witchcraft," feiticeiro "sorcerer, wizard." Latin facticius in Spanish has become hechizo "artificial, imitated," also "bewitchment, fascination."

The specific Portuguese use of the word that brought it to English probably began among Portuguese sailors and traders who used the word as a name for charms and talismans worshipped by the inhabitants of the Guinea coast of Africa. It was picked up and popularized in anthropology by Charles de Brosses' "Du culte des dieux fétiches" (1760), which influenced the word's spelling in English (French fétiche also is borrowed 18c. from the Portuguese word).
Any material image of a religious idea is an idol; a material object in which force is supposed to be concentrated is a Fetish; a material object, or a class of material objects, plants, or animals, which is regarded by man with superstitious respect, and between whom and man there is supposed to exist an invisible but effective force, is a Totem. [J. Fitzgerald Lee, "The Greater Exodus," London, 1903]
Figurative sense of "something irrationally revered, object of blind devotion" appears to be an extension made by the New England Transcendentalists (1837). For sexual sense (1897), see fetishism.
fetishism (n.)youdaoicibaDictYouDict
1801, "worship of fetishes," from fetish + -ism. Expanded in use by Comte taking it to denote a general type of primitive religion (animism). In the purely psycho-sexual sense, first recorded 1897 in writings of Henry Havelock Ellis (1859-1939).
In certain perversions of the sexual instinct, the person, part of the body, or particular object belonging to the person by whom the impulse is excited, is called the fetish of the patient. [E. Morselli in "Baldwin Dictionary of Philosophy," 1901]
Related: Fetishist (1845; psycho-sexual sense from 1897); fetishistic.
fetlock (n.)youdaoicibaDictYouDict
"tuft of hair behind the pastern-joint of a horse," early 14c., fetlak, from a Germanic source (cognates: Dutch vetlock, Middle High German fizlach, German Fiszloch), perhaps from Proto-Germanic *fetel- (source of German fessel "pastern"), from PIE *ped-el-, from root *ped- (1) "foot" (see foot (n.)). The Middle English diminutive suffix -ok (from Old English -oc) was misread and the word taken in folk etymology as a compound of feet and lock (of hair).
fetor (n.)youdaoicibaDictYouDict
"offensive smell," mid-15c., from Latin fetor, foetor "stink, stench, bad smell," from fetere "have a bad smell" (see fetid).

fetter (n.)youdaoicibaDictYouDict
Old English fetor "chain or shackle by which a person or animal is bound by the feet," figuratively "check, restraint," from Proto-Germanic *fetero (cognates: Old Saxon feteros (plural), Middle Dutch veter "fetter," in modern Dutch "lace, string," Old High German fezzera, Old Norse fiöturr, Swedish fjätter "fetter"), from PIE root *ped- (1) "foot" (see foot (n.)). The generalized sense of "anything that shackles" had evolved in Old English. Related Fetters.

fettle (n.)youdaoicibaDictYouDict
"condition, state, trim," c. 1750, in a glossary of Lancashire dialect, from northern Middle English fettle (v.) "to make ready, fix, prepare, arrange" (late 14c.), which is of uncertain origin, perhaps akin to Old English fetian "to fetch" (see fetch (v.)); perhaps from Old English fetel "a girdle, belt," from Proto-Germanic *fatilaz (cognates: German fessel "fetter, chain," Old Norse fetill "strap, brace"), from PIE *ped- (2) "container" (see vat). Related: Fettler; fettling.

fetus (n.)youdaoicibaDictYouDict
late 14c., "the young while in the womb or egg" (tending to mean vaguely the embryo in the later stage of development), from Latin fetus (often, incorrectly, foetus) "the bearing or hatching of young, a bringing forth," from Latin base *fe- "to generate, bear," also "to suck, suckle" (see fecund).

In Latin, fetus sometimes was transferred figuratively to the newborn creature itself, or used in a sense of "offspring, brood" (as in Horace's "Germania quos horrida parturit Fetus"), but this was not the basic meaning. It also was used of plants, in the sense of "fruit, produce, shoot," and figuratively as "growth, production." The spelling foetus is sometimes attempted as a learned Latinism, but it is not historic.
feu de joie (n.)youdaoicibaDictYouDict
public bonfire, French, literally "fire of joy."
feud (n.)youdaoicibaDictYouDict
c. 1300, fede "enmity, hatred, hostility," northern English and Scottish, ultimately (via an unrecorded Old English word or Old French fede, faide "war, raid, hostility, hatred, enmity, feud, (legal) vengeance," which is from Germanic) from Proto-Germanic *faihitho (compare Old High German fehida "contention, quarrel, feud"), noun of state from adjective *faiho- (cognates: Old English fæhð "enmity," fah "hostile;" German Fehde "feud;" Old Frisian feithe "enmity").

This is from PIE root *peig- (2), also *peik- "evil-minded, hostile" (see foe). Sense of "vendetta" is early 15c. Alteration of spelling in 16c. is unexplained. Meaning "state of hostility between families or clans" is from 1580s.
