noun
Refers to a man in the context of marriage, often from the perspective of his bride or her family. Can mean 'husband' or specifically 'groom' at a wedding.

noun
Used to refer to one's own son-in-law or someone else's son-in-law. The possessive 'one's' is implied by context; the word itself does not inherently mean 'my'.

He is my son-in-law.
婿と一緒に釣りに行った。
I went fishing with my son-in-law.
Rarely used kanji form.
The kanji 婿 is composed of 女 (woman) and 胥 (assistant), suggesting a man who assists or joins a woman's family. The reading むこ is of native Japanese origin, but its exact derivation is uncertain.
