Related: Craftily; craftiness.[crafty etymology, crafty origin, 英语词源]
cunning (adj.): early 14c., "learned, skillful," present participle of cunnen "to know" (see can (v.1)). Sense of "skillfully deceitful" is probably late 14c. As a noun from c. 1300. Related: Cunningly.
fine (adj.): mid-13c., "unblemished, refined, pure, free of impurities," also "of high quality, choice," from Old French fin "perfected, of highest quality" (12c.), a back-formation from finire or else from Latin finis "that which divides, a boundary, limit, border, end" (see finish (v.)); hence "acme, peak, height," as in finis boni "the highest good." The English word is from c. 1300 as "rich, valuable, costly;" also in a moral sense "true, genuine; faithful, constant." From late 14c. as "expertly fashioned, well or skillfully made," also, of cloth, "delicately wrought." Of weapons or edges, "sharp" from c. 1400. In reference to quality of gold and silver, late 15c.

In French, the main meaning remains "delicate, intricately skillful;" in English since c. 1300 fine has been also a general broad expression of admiration or approval, the equivalent of French beau (as in fine arts, 1767, translating French beaux-arts). Related: Finer; finest. Fine print is from 1861 as "type small and close-set;" by 1934 in the extended sense "qualifications and limitations of a deal."
machination (n.): late 15c., "a plotting, intrigue," from Old French machinacion "plot, conspiracy, scheming, intrigue," from Latin machinationem (nominative machinatio) "device, contrivance, machination," noun of action from past participle stem of machinari "contrive skillfully, to design; to scheme, to plot," from machina (see machine (n.)). Related: Machinations.

precarious (adj.): 1640s, a legal word, "held through the favor of another," from Latin precarius "obtained by asking or praying," from prex (genitive precis) "entreaty, prayer" (see pray). Notion of "dependent on the will of another" led to extended sense "risky, dangerous, uncertain" (1680s). "No word is more unskillfully used than this with its derivatives. It is used for uncertain in all its senses; but it only means uncertain, as dependent on others ..." [Johnson]. Related: Precariously; precariousness.
pretty (adj.): Old English prættig (West Saxon), pretti (Kentish), *prettig (Mercian) "cunning, skillful, artful, wily, astute," from prætt, *prett "a trick, wile, craft," from Proto-Germanic *pratt- (cognates: Old Norse prettr "a trick," prettugr "tricky;" Frisian pret, Middle Dutch perte, Dutch pret "trick, joke," Dutch prettig "sportive, funny," Flemish pertig "brisk, clever"), of unknown origin.

Connection between Old English and Middle English words is uncertain, but if they are the same, meaning had shifted by c. 1400 to "manly, gallant," and later moved via "attractive, skillfully made," to "fine," to "beautiful in a slight way" (mid-15c.). Ironical use from 1530s. For sense evolution, compare nice, silly. Also used of bees (c. 1400). "After the OE. period the word is unknown till the 15th c., when it becomes all at once frequent in various senses, none identical with the OE., though derivable from it" [OED].

quaint (adj.): c. 1200, cointe, "cunning, ingenious; proud," from Old French cointe "knowledgeable, well-informed; clever; arrogant, proud; elegant, gracious," from Latin cognitus "known, approved," past participle of cognoscere "get or come to know well" (see cognizance). Modern spelling is from early 14c.

Later in English, "elaborate, skillfully made" (c. 1300); "strange and clever" (mid-14c.). Sense of "old-fashioned but charming" is first attested 1795, and could describe the word itself, which had become rare after c. 1700 (though it soon recovered popularity in this secondary sense). Related: Quaintly; quaintness.
ricochet (n.): 1769, from ricochet (v.) or French ricochet "the skipping of a shot or of a flat stone on water," but in earliest French use (15c.) "verbal to-and-fro," and only in the phrase fable du ricochet, an entertainment in which the teller of a tale skillfully evades questions, and chanson du ricochet, a kind of repetitious song; of uncertain origin.

No reason for the -ch- spelling, which dates to 13c. Whited sepulchre "hypocrite" is from Matt. xxiii.27.
skillful (adj.): also skilful, early 14c., from skill + -ful. Related: Skillfully; skilfully.
tool (v.): "to drive a vehicle," 1812, probably from tool (n.) as if "to manage skillfully." The meaning "to work or shape with a tool" is recorded from 1815; that of "equip (a factory) with machine tools" is from 1927. Related: Tooled; tooling.
unskillful (adj.): also unskilful, late 14c., "foolish," from un- (1) "not" + skillful (adj.). Meaning "inexpert" is from 1560s. Related: Unskillfully.
