History
Etymology
From Middle English flawe, flay (“a flake of fire or snow, spark, splinter”), probably from Old Norse flaga (“a flag or slab of stone, flake”), from Proto-Germanic *flagō (“a layer of soil”), from Proto-Indo-European *plok- (“broad, flat”). Cognate with Icelandic flaga (“flake”), Swedish flaga (“flake, scale”), Danish flage (“flake”), Middle Low German vlage (“a layer of soil”), Old English flōh (“a fragment, piece”).
From Middle English *flaugh, from Middle Dutch vlāghe or Middle Low German vlāge, ultimately from Proto-West Germanic *flagā. Or, possibly of North Germanic origin, from Swedish flaga (“gust of wind”), from Old Norse flaga; all from Proto-Germanic *flagǭ (“blow, strike”). See modern Dutch vlaag (“gust of wind”).
