gallop

Etymology

From Middle English galopen (“to gallop”), from Old French galoper (compare modern French galoper), from Frankish *wala hlaupan (“to run well”), from *wala (“well”) + *hlaupan (“to run”), from Proto-Germanic *hlaupaną (“to run, leap, spring”), from Proto-Indo-European *klaup-, *klaub- (“to spring, stumble”). Possibly also derived from a deverbal of Frankish *walhlaup (“battle run”) from *wal (“battlefield”) from a Proto-Germanic word meaning "dead, victim, slain" from Proto-Indo-European *wel- (“death in battle, killed in battle”) + *hlaup (“course, track”) from *hlaupan (“to run”). More at well, leap, valkyrie. See also the doublet wallop, coming from the same source through an Old Northern French variant.
