1811, from stem of fetus + -al (1).
fetch (v.) Look up fetch at Dictionary.com
Middle English fecchen, from Old English feccan "to bring, bring to; seek, gain, take," apparently a variant of fetian, fatian "bring near, bring back, obtain; induce; marry," which is probably from Proto-Germanic *fetan (source also of Old Frisian fatia "to grasp, seize, contain," Old Norse feta "to find one's way," Middle Dutch vatten, Old High German sih faggon "to mount, climb," German fassen "to grasp, contain").

This would connect it to the PIE verbal root *ped- "to walk," from *ped- (1) "foot" (see foot (n.)). With widespread sense development: to "reach," "deliver," "effect," "make (butter), churn" (19c.), "restore to consciousness" (1620s), also various nautical senses from 16c.-17c.; meaning "to bring in as equivalent or price" is from c. 1600. In 17c. writers on language didn't derive a word's etymology; they fetched it. As what a dog does, c. 1600, originally fetch-and-carry. Variant form fet, a derivation of the original Old English version of the word, survived as a competitor until 17c. Related: Fetched; fetching.
fetch (n.1) Look up fetch at Dictionary.com
"apparition of a living person, specter, a double," 1787, an English dialect word of unknown origin (see OED for discussion).
A peculiarly weird type of apparition is the wraith (q.v.) or double, of which the Irish fetch is a variant. The wraith is an exact facsimile of a living person, who may himself see it. Goethe, Shelley, and other famous men are said to have seen their own wraiths. The fetch makes its appearance shortly before the death of the person it represents, either to himself or his friends, or both. [Lewis Spence, "An Encyclopedia of Occultism," 1920]

fetish (n.) Look up fetish at Dictionary.com
"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.) Look up fetishism at Dictionary.com
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.

"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).

fetus (n.) Look up fetus at Dictionary.com
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.

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- (source also of 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.

fever (n.) Look up fever at Dictionary.com
earlier also feaver, late Old English fefor, fefer "fever, temperature of the body higher than normal," from Latin febris "fever," related to fovere "to warm, heat," probably from PIE root *dhegh- "burn" (source also of Gothic dags, Old English dæg "day," originally "the heat;" Greek tephra "ashes"); but some suggest a reduplication of a root represented by Sanskrit *bhur- "to be restless."

The Latin word was adopted into most Germanic languages (German Fieber, Swedish feber, Danish feber), but not in Dutch. English spelling influenced by Old French fievre. Alternative to Old English hrið, hriðing (cognate with Old High German hritto, Irish crith, Welsh cryd, Lithuanian skriečiù). Extended sense of "intense nervous excitement" is from 1580s. Also as a verb in Old English, feferian.

Old English feawe (plural; contracted to fea) "not many, a small number; seldom, even a little," from Proto-Germanic *faw- (source also of Old Saxon fa, Old Frisian fe, Old High German fao, Old Norse far, Danish faa).

This is from PIE root *pau- (1) "few, little" (source also of Latin paucus "few, little," paullus "little," parvus "little, small," pauper "poor;" Greek pauros "few, little," pais (genitive paidos) "child;" Latin puer "child, boy," pullus "young animal;" Oscan puklu "child;" Sanskrit potah "a young animal," putrah "son;" Old English fola "young horse;" Old Norse fylja "young female horse;" Old Church Slavonic puta "bird;" Lithuanian putytis "young animal, young bird").

Always plural in Old English, according to OED "on the analogy of the adverbial fela," meaning "many." Phrase few and far between attested from 1660s. Unusual ironic use in quite a few "many" (1854), earlier a good few (1803).
There is likewise another dialectical use of the word few among them [i.e. "the Northern Counties"], seemingly tending to its total overthrow; for they are bold enough to say--"a good few," meaning a good many. [Samuel Pegge, "Anecdotes of the English Language," London, 1803]

Preserved in Scottish. Sense of "displaying unearthly qualities" and "disordered in the mind (like one about to die)" led to modern ironic sense of "affected."

fiancee (n.) Look up fiancee at Dictionary.com
"woman to whom one is betrothed," 1844 (1837 as a French word in English), from French fiancée, fem. of fiancé, past participle of fiancer "to betroth," from fiance "a promise, trust," from fier "to trust," from Vulgar Latin *fidare "to trust," from Latin fidus "faithful" from the same root as fides "faith" (see faith).

fianchetto (n.) Look up fianchetto at Dictionary.com
chess move, 1847, Italian, diminutive of fianco "flank (attack)," from Old French flanc "hip, side" (see flank (n.)).
fiasco (n.) Look up fiasco at Dictionary.com
1855, theater slang for "a failure in performance;" by 1862 it had acquired the general sense of "any ignominious failure or dismal flop," on or off the stage. It comes via the French phrase fiare fiasco "turn out a failure" (19c.), from Italian far fiasco "suffer a complete breakdown in performance," literally "make a bottle," from fiasco "bottle," from Late Latin flasco "bottle" (see flask).

The literal sense of the image (if it is one) is obscure today, but "the usual range of fanciful theories has been advanced" [Ayto]. Century Dictionary says "perhaps in allusion to the bursting of a bottle," Weekley pronounces it impenetrable and compares French ramasser un pelle "to come a cropper (in bicycling), literally to pick up a shovel." OED keeps its distance and lets nameless "Italian etymologists" make nebulous reference to "alleged incidents in Italian theatrical history." Klein suggests Venetian glass-crafters tossing aside imperfect pieces to be made later into common flasks. But according to an Italian dictionary, fare il fiasco used to mean "to play a game so that the one that loses will pay the fiasco," in other words, he will buy the next bottle (of wine). If the dates are not objectionable, that plausibly connects the literal sense of the word with the notion of "a costly mistake."
fiat (n.) Look up fiat at Dictionary.com
1630s, "authoritative sanction," from Latin fiat "let it be done" (used in the opening of Medieval Latin proclamations and commands), third person singular present subjunctive of fieri "be done, become, come into existence," used as passive of facere "to make, do" (see factitious).
