| Alternative spelling |
|---|
| 息う |
From Old Japanese. Attested in the Nihon Ryōiki (810-824). Also cited to the Nihon Shoki of 720,[1] however, that may only be traceable to supplemental glosses added later to the kanbun original. In turn, from Proto-Japonic *yukəpu.
Considering the senses, and that the alternative kanji spelling with 息 was used for the Nihon Shoki kana gloss attestation, the term is likely derived from, or otherwise related to, 息 (iki, “breath, breathing”).
