団扇
うちわ · uchiwa · JLPT N1 · noun
fan
🪭 団 = round + 扇 = fan: a round fan, uchiwa
団 means round and 扇 means fan. An uchiwa is a flat, round fan with a handle, not a folding one, which is why the round kanji comes first.
扇 — door 戶 + feather 羽
扇 combines 戶 (door) above 羽 (feathers), originally depicting a door-leaf made of woven feathers or a feathered fan that swings like a door. The image extended to flat hand-fans, then by association to anything that fans, fluffs, or stirs up — including the verb 'to fan' and a measure word for doors and windows.
