feather

feather: [OE] The concept of ‘feathers’ is closely bound up with those of ‘wings’ and ‘flying’, and not surprisingly feather belongs to a word family in which all three of these meanings are represented. Its ultimate source is the prehistoric Indo-European base *pet-, which also produced Greek ptéron ‘wing’ (as in English pterodactyl), Latin penna ‘feather, wing’ (source of English pen), and Sanskrit pátati ‘fly’. Its Germanic descendant was *fethrō, from which came German feder, Dutch veer, Swedish fj?der and English feather (itself used in the plural for ‘wings’ in Anglo-Saxon times).
=> pen, pterodactyl

feather (n.)

Old English feeer "a feather; a pen," in plural, "wings," from Proto-Germanic *fethro (cognates: Old Saxon fethara, Old Norse fiotr, Swedish fj?der, Middle Dutch vedere, Dutch veder, Old High German fedara, German Feder), from PIE *pet-ra-, from root *pet- "to rush, to fly" (see petition (n.)). Feather-headed "silly" is from 1640s. Feather-duster attested by 1835. Figurative use of feather in (one's) cap attested by 1734. Birds of a feather "creatures of the same kind" is from 1580s.

feather (v.)

Old English fieerian "to furnish with feathers or wings," from feeer (see feather (n.)). Meaning "to fit (an arrow) with feathers" is from early 13c.; that of "to deck, adorn, or provide with plumage" is from late 15c. In reference to oars (later paddles, propellers, etc.) from 1740, perhaps from the notion of the blade turned edgewise, or from the spray of the water as it falls off (compare nautical feather-spray, that produced by the cutwater of a fast vessel). The noun in reference to this is from the verb. Meaning "cut down to a thin edge" is from 1782, originally in woodworking. Phrase feather one's nest "enrich oneself" is from 1580s.
