- gallant[gallant 词源字典]
- gallant:  Gallant originated as the present participle of Old French galer ‘make merry, rejoice’. This probably came from Gallo- Romance *walāre, a derivative of Frankish *wala ‘well’ (of which English well is a relative). Following its French model, the English adjective originally meant ‘showy, splendid, gorgeous’ as well as ‘spirited, brave’ and ‘courteous, polished’ (the last of which led in the 17th century to ‘courteously attentive to women’ and ‘amorous’). Regale  too goes back to Old French galer.

- gallant (adj.)
- mid-15c., "showy, finely dressed; gay, merry," from Old French galant "courteous," earlier "amusing, entertaining; lively, bold" (14c.), present participle of galer "rejoice, make merry," which is of uncertain origin. Perhaps from a Latinized verb formed from Frankish *wala- "good, well," from Proto-Germanic *wal- (source also of Old High German wallon "to wander, go on a pilgrimage"), from PIE root *wel- (2) "to wish, will" (see will (v.)), "but the transition of sense offers difficulties that are not fully cleared up" [OED]. Sense of "politely attentive to women" was adopted early 17c. from French. Attempts to distinguish this sense by accent are an 18c. artifice.
