affairyoudaoicibaDictYouDict
affair: [13] Like ado, and of course to-do, affair originally meant literally ‘to do’. It was coined in Old French from the phrase à faire ‘to do’, and entered English via Anglo-Norman afere. The spelling affair was established by Caxton, who based it on the French model. The specific sense of a ‘love affair’ dates from the early 18th century.

fail: [13] Fail, fallacy [15], fallible, false, and fault all come ultimately from the same source – the Latin verb fallere. This originally meant ‘deceive’, but it developed semantically to ‘deceive someone’s hopes, disappoint someone’, and in its Vulgar Latin descendant *fallīre this meaning had progressed to ‘be defective, fail’. English acquired the word via Old French faillir. Its Anglo-Norman form, failer, came to be used as a noun, and is the source of English failure [17].

faintyoudaoicibaDictYouDict
faint: [13] Faint comes from Old French faint, which was originally the past participle of the verb faindre, feindre ‘pretend, shirk’ (whence English feign). This meant ‘pretended, simulated’, ‘lazy, shirking’, and ‘cowardly’, and all these senses were originally taken over by English. None now survives except the last, in the phrase faint heart, but in their place the underlying notion of ‘feebleness’ has produced ‘not bright, dim’ and ‘weak and dizzy’. The verb, based on the second of these, developed in the late 14th century. The variant spelling feint, used of printed lines, was introduced in the mid 19th century.

fair: English has two distinct words fair, one Germanic and the other Romance. The older, meaning ‘beautiful’ [OE], comes from a prehistoric Germanic *fagraz, which survives also in Swedish fager ‘beautiful’. It derived from a base *fag-, which seems originally to have meant ‘fitting, suitable’ (a variant of it was the ultimate source of fake and possibly also of the now archaic noun fig ‘clothes, array’, as in ‘in full fig’).

Of its main present-day meanings, ‘just, equitable’ developed in the 14th century and ‘not dark’ in the mid 16th century. Fair ‘festive event’ [13] comes from Old French feire. This was a descendant of late Latin fēria, a singular use of a noun which in classical times had been used in the plural, fēriae, for ‘holiday’. A close relative of fēriae was the adjective festus ‘joyous’, source of English feast, festival, festoon, and fête.

fairyyoudaoicibaDictYouDict
fairy: [14] Fairy is an Old French coinage. It comes from Old French faerie, which meant ‘enchantment, magic’ and was derived from fae ‘fairy’ (source of English fay [14]). This in turn came from the Latin plural fāta, used in personifying the Fates, three goddesses who in ancient mythology governed human destiny. The original notion of the French noun survives in the mock-medieval term faerie (introduced by Edmund Spenser in his Faerie Queene 1590), but in fairy itself it has been gradually replaced by the meaning of the word from which it was originally derived – fay.

faithyoudaoicibaDictYouDict
faith: [12] Faith comes ultimately from the prehistoric Indo-European *bhidh-, *bhoidh- (source also of English federal). It produced Latin fidēs ‘faith’, which lies behind a wide range of English words, including confide, defy, diffident (which originally meant ‘distrustful’), fealty [14], fidelity [15], fiduciary [17], and perfidy [16].

Its descendants in the Romance languages include Italian fede, Portuguese (as in auto-da-fé, literally ‘act of faith’, acquired by English in the 18th century), and Old French feid. This was pronounced much as modern English faith is pronounced, and Middle English took it over as feth or feith. (A later Old French form fei, foreshadowing modern French foi, produced the now defunct English fay [13]).

savoir-faire: see sapient
affair (n.)youdaoicibaDictYouDict
c. 1300, "what one has to do," from Anglo-French afere, Old French afaire "business, event; rank, estate" (12c., Modern French affaire), from the infinitive phrase à faire "to do," from Latin ad "to" (see ad-) + facere "to do, make" (see factitious).

A Northern word originally, brought into general use and given a French spelling by Caxton (15c.). General sense of "vague proceedings" (in romance, war, etc.) first attested 1702.

Thus, in our dialect, a vicious man is a man of pleasure, a sharper is one that plays the whole game, a lady is said to have an affair, a gentleman to be a gallant, a rogue in business to be one that knows the world. By this means, we have no such things as sots, debauchees, whores, rogues, or the like, in the beau monde, who may enjoy their vices without incurring disagreeable appellations. [George Berkeley, "Alciphron or the Minute Philosopher," 1732]

But that was before Tolkien. As a type of supernatural being from late 14c.

As a name for the diminutive winged beings in children's stories from early 17c.
Yet I suspect that this flower-and-butterfly minuteness was also a product of "rationalization," which transformed the glamour of Elfland into mere finesse, and invisibility into a fragility that could hide in a cowslip or shrink behind a blade of grass. It seems to become fashionable soon after the great voyages had begun to make the world seem too narrow to hold both men and elves; when the magic land of Hy Breasail in the West had become the mere Brazils, the land of red-dye-wood. [J.R.R. Tolkien, "On Fairy-Stories," 1947]

And faith is neither the submission of the reason, nor is it the acceptance, simply and absolutely upon testimony, of what reason cannot reach. Faith is: the being able to cleave to a power of goodness appealing to our higher and real self, not to our lower and apparent self. [Matthew Arnold, "Literature & Dogma," 1873]
From late 14c. as "confidence in a person or thing with reference to truthfulness or reliability," also "fidelity of one spouse to another." Also in Middle English "a sworn oath," hence its frequent use in Middle English oaths and asseverations (par ma fay, mid-13c.; bi my fay, c. 1300).

Also faith healer, attested by 1874; from faith + healer. Faith-curer is from 1883.
The power which a man's imagination has over his body to heal it or make it sick is a force which none of us is born without. The first man had it, the last one will possess it. If left to himself, a man is most likely to use only the mischievous half of the force--the half which invents imaginary ailments for him and cultivates them; and if he is one of those very wise people, he is quite likely to scoff at the beneficent half of the force and deny its existence. [Mark Twain, "Christian Science," 1907]
