quail: Quail the bird [14] and quail ‘cower’ [15] are not related. The former comes via Old French quaille from medieval Latin coacula, which probably originated in imitation of the bird’s grating cry. It is not known for certain where the verb (which originally meant ‘decline, wither, give way’) came from, although some have linked it with another verb quail, now obsolete, which meant ‘curdle’. This came via Old French quailler from Latin coāgulāre, source of English coagulate.

(early 14c. as a surname (Quayle), from Old French quaille (Modern French caille), perhaps via Medieval Latin quaccula (source also of Provençal calha, Italian quaglia, Old Spanish coalla), or directly from a Germanic source (compare Dutch kwakkel, Old High German quahtala "quail," German Wachtel, Old English wihtel), imitative of the bird's cry.

quail (v.)youdaoicibaDictYouDict
c. 1400, "have a morbid craving;" early 15c., "grow feeble or sick;" mid-15c., "to fade, fail, give way," of unknown origin, perhaps from Middle Dutch quelen "to suffer, be ill," from Proto-Germanic *kwaljan, from PIE *gwele- (1) "to throw, to pierce" (see quell). Or from obsolete quail "to curdle" (late 14c.), from Old French coailler, from Latin coagulare (see coagulate). Sense of "lose heart, shrink, cower" is attested from 1550s. According to OED, common 1520-1650, then rare until 19c., when apparently it was revived by Scott. Related: Quailed; quailing.
