扇風機
せんぷうき · senpuuki · JLPT N2 · noun
electric fan
扇風機 = 扇 fan + 風 wind + 機 machine: a machine that makes wind
Read it as fan + wind + machine: 扇 (sen) is fan, 風 (fuu) is wind, 機 (ki) is machine. The 風 in the middle is the key part for the wind.
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.
