History

Etymology

Unclear: * Possibly from French floche (“tuft of wool”), from floc, from Old French flosche (“down, velvet”), from Latin floccus (“piece of wool”), probably from Frankish *flokkō (“down, wool, flock”), from Proto-Germanic *flukkô (“down, piece of wool, flock”), from Proto-Indo-European *plewk- (“hair, fibres, tuft”). * Or, from Middle English *flos (attested in Middle English Flosmonger (a surname)), from Proto-West Germanic *fleus, related to English fleece. Cognate with Old High German flocko (“down”), Middle Dutch vlocke (“flock”), Norwegian dialectal flugsa (“snowflake”), Dutch flos (“plush”) (tr=17c.).

From dialectal flosh (“a flush, stream of water, sluice”), from Middle English flosche, flusche, flasche, flaske (“a watery or marshy place, swamp”), perhaps from Old French flache, from Middle Dutch vlacke (“a flat area, plain”), ultimately related to Proto-West Germanic *fleutan. Compare also German Floss (“a float”).

Origin obscure. Perhaps of North Germanic origin. Compare Norwegian flos, flus (“rind, scale, strip peeled off”).
