揺蕩い

/tajutapi/ → /tajutafi/ → /tajutai/

From Old Japanese 揺蕩ひ (tayutapi). Appears in the Man'yōshū of 759 CE.^[1][2]

Derived as the 連(れん)用(よう)形(けい) (ren'yōkei, “stem or continuative form”) of the verb 揺蕩(たゆた)う (tayutau, “to bob, to pause, to hesitate”).^[1][2][3][4]

The kanji spelling is an example of jukujikun (熟字訓), based on the synonymous Middle Chinese-derived term 揺蕩 (yōtō).

• (Tokyo) たゆたい [tàyútáꜜì] (Nakadaka – [3])^[2][4]
