Etimoloji
/afuɡi/ → */awuɡi/ → /auɡi/ → /ɔːɡi/ → /oːɡi/ Originally the continuative or noun stem form of verb 扇ぐ (aogu, “to fan, to wave something to create a breeze”). The change in vowels represents a regular historical sound shift. Ultimately from Proto-Japonic *aponki. First cited to the late 900s.
