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.).
