Comments:KW 165, EAS 47, SKE 91-2. The Kor. parallel is found only there; as for the Japanese word, it is not attested in any OJ or MJ sources, so the PJ reconstruction is uncertain. One should also note irregular PJ vocalism and tone (*-a- with high tone would be expected). This all makes the Kor.-Jpn. aspect of the etymology dubious.
