The word 'featherier' is derived from 'feather' (from Old English 'feðer', meaning a structure that covers birds) and the suffix '-ier' (meaning one who or that which). Thus, 'featherier' refers to something that is more like or characterized by feathers.
Think of 'feather' as the covering of birds, and '-ier' indicating a person or thing that has more of that quality. So, 'featherier' means something that has more feathers or is more feather-like.
