• Dai Kanwa Jiten: character 19360
• Dae Jaweon: page 1092, character 24
• Hanyu Da Zidian (first edition): volume 3, page 2230, character 10

Phono-semantic compound (形聲／形声, OC *ŋjed) : phonetic 埶 (OC *ŋeds) + semantic 灬 (“fire”).

Schuessler (2024) considers this a *-t derivation of Proto-Sino-Tibetan *nwe (“warm”), whence also Burmese နွေး (nwe:, “warm; lukewarm”), နွှေး (hnwe:, “to warm something; to revise”).

Often considered to be related to 爇 (OC *ŋʷjed, “to burn; to toast”) and 焫 (OC *njod, “hot”).
