婿

1. son-in-law
2. husband

(common “Jōyō” kanji)

• Go-on: さい (sai)
• Kan-on: せい (sei, Jōyō)
• Kun: むこ (muko, 婿, Jōyō)

*/moko/ → *⟨muko₁⟩ → */mukʷo/*⟨mo₍₁₎ko₁⟩ → */mʷokʷo/[1] → /muko/

Found in the Nihon Shoki of 720 CE with the ideographic spelling 聟.[2]

Although the reading muko is not confirmed in Old Japanese documents, the presence of cognate words suggests that this may be from Proto-Japonic *moko (cognate with Okinawan むーく (mūku), Kunigami むふ (muhu), Miyako むく (muku) and the moko below). This would be the a result of a phonological change, whereby non-final */o/ in Proto-Japonic nouns shifted to become /u/ in Central Old Japanese.

In regard to the derivation, there are some theories proposed, however many of them are associated with the verbs 向かう (mukau, “to go towards”) and 迎える (mukaeru, “to receive”), both derived from 向く (muku, “to turn toward”), from Proto-Japonic *muk-, from the idea of "the facing party, the other person (of a pair)"; see also 向こう (mukō, “the other side, the facing side”). Theories to explain this inconsistency in the proto-forms have not been published yet.
