plume: [14] Latin plūma originally denoted ‘down, feathers’ (it is probably related to English fleece). Eventually, though, it came to signify a ‘single feather’, and evolved in this sense to Italian piuma, Spanish pluma, and French plume – source of English plume. The derivative plumage [15] originated in Old French. => fleece, plumage
