The kanji "婿" is a phono-semantic compound, formed by combining the semantic component "女" (woman) with the phonetic component "胥" (xū). The "女" radical indicates the character's relation to marriage or a female connection, while "胥" primarily provides its sound but also carries a connotation of "mutual" or "assisting." This construction reflects the concept of a man who joins a woman's family through marriage. Etymologically, "婿" originates from ancient Chinese, where it depicted a man who marries into his wife's family. In its earliest forms in bronze script and later small seal script, the character maintained this structure. The "胥" component itself is composed of "疋" (foot/step) over "月" (meat/moon, originally a pictograph of a plate of meat), suggesting a person who brings offerings or serves—a role fitting for a groom integrating into a new household. This character was standardized during the small seal script reform in the Qin dynasty before evolving into its modern clerical and regular script forms. The kanji arrived in Japan around the 5th-6th centuries CE, imported alongside Buddhism and Chinese writing system. Japan adopted both the character and its meaning, though the practice of mukoiri (婿入り), where the groom lives with the bride's family, made the character particularly culturally resonant. Interestingly, while "婿" refers specifically to a son-in-law or groom, the Japanese reading "muko" is a native Japanese word (yamato kotoba) that existed prior to the kanji's importation, demonstrating how a pre-existing concept was mapped onto an appropriate Chinese character.
