Etymology[edit]

A compound of 五段 (godan, five grades) and 活用 (katsuyō, conjugation). An extension of the 四段活用 (yodan katsuyō) conjugation class, the fifth base, -o, is a pseudo base derived from the suffix -o attaching to the irrealis conjugation resulting in -au, which phonologically regularly elides into [oː].
