⚫︎ 婿入り Translation: Entering a family as a son-in-law (getting married and moving into the wife's family home). ⚫︎ 婿養子 Translation: A son-in-law adopted into the family (often to continue the family name). ⚫︎ 花婿 Translation: Bridegroom (more formal term for the groom).

The kanji 婿 is a 形声文字 (keishō moji) or phono-semantic compound. It combines the phonetic element 女 (onna), meaning "woman," "female," or "daughter," with the semantic element 胥 (sho), which contributes the sound and originally meant "help." This combination suggests a man who "helps" the woman (the wife) and her family, implying a relationship of support and integration within the family unit. Over time, the meaning specifically narrowed to the concept of son-in-law.
