Selected source glosses provide context, not a complete modern definition inventory

From earlier floow (“woolly substance, down, nap, lint”), also spelt flough, flue, and flew, from West Flemish vluwe, of uncertain ultimate origin: * Compare Old English flōh (“that which is flown off, fragment, piece”); see flaw * Possibly representing a blend of flue + puff; compare Middle Dutch vloe, or perhaps onomatopoeic; compare dialectal English floose, flooze, fleeze (“particles of wool or cotton; fluff; loose threads or fibres”), Danish fnug (“down, fluff”), Swedish fnugg (“speck, flake”). * Alternatively, West Flemish vluwe may derive from French velu (“hairy, furry”), from Latin villūtus (“having shaggy hair”), from villus (“shaggy hair, tuft of hair”). For words of similar sound and meaning in other languages, compare Japanese フワフワ (fuwafuwa, “lightly, softly”), Hungarian puha (“soft, fluffy”), Polish puchaty (“soft, fluffy”), Romanian puf (“down, peachfuzz, soft hair of some animals, powderpuff”).

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
