wallop

Etymology 1

From Middle English wallopen (“gallop”), from Anglo-Norman [Term?], from Old Northern French walop (“gallop”, noun) and waloper (“to gallop”, verb) (compare Old French galoper, whence 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 *klaub- (“to spring, stumble”). Possibly also derived from a deverbal of Frankish *walhlaup (“battle run”) from *wal (“battlefield”) from Proto-Germanic [Term?] (“dead, victim, slain”) from Proto-Indo-European *wel- (“death in battle, killed in battle”) + *hlaup (“course, track”) from *hlaupan (“to run”). Compare the doublet gallop.
