Things that are soft, light, and downy can be described as feathery. After you brush your dog, you'll find his feathery fur all over the house.
Feathery things, from your sister's feathery hairdo to the feathery branches of the willow tree in your yard, look or feel like feathers. You can use this adjective for anything that resembles the light, fluffy down of a baby bird or the graceful plumage of a swan. Feathery comes from feather and its root meaning "to fly."
