From Middle English fleme, fleom, from Old French flieme, flemie (“open vein”), probably via a Proto-Germanic source (compare Old Saxon flēma, Old High German fliotuma, fliodema, 古期英語 flȳtme, flītme (“fleam, lancet”)), borrowed from Vulgar Latin fletoma, *fletomus, from Late Latin flebotomus, phlebotomus, from Ancient Greek φλεβοτόμον (phlebotómon). Compare French flamme, Dutch vlijm, German Fliete, Danish flitte (“fleam”). Doublet of phlebotome.
From Middle English fleem, flem (“the rushing of water; current”), probably from 古期英語 flēam (“fleeing; flight; rush”), from Proto-Germanic *flaumaz (“stream; current; flood”), from Proto-Indo-European *plew- (“to fly; flow; run”). Cognate with Norwegian Nynorsk flaum (“flood”).
From Proto-Germanic *flaumaz.
