feather
UK: ˈfeðə | US: ˈfeðər
n. 1. One of the light, horny structures forming the plumage of birds, used for flight, insulation, and display.
n. 2. A feather-like object or part (e.g., in archery or decoration).
vt. 3. To cover or adorn with feathers.
The word "feather" traces back to Old English feþer, derived from Proto-Germanic feþrō, linked to the verb fǣtan (to adorn or form). The morpheme feat reflects the idea of shaping or crafting (as feathers are finely structured), while -her suggests belonging or attachment (as feathers belong to birds). This dual logic captures both the functional and possessive nature of feathers in avian biology.
