The kanji 婚 is a phono-semantic compound (形声文字). It combines the radical 女 (おんな, "woman") with the phonetic component 昏 (こん, "darkness," "twilight"). The component 昏 suggests the act of marriage often occurring at twilight or in the evening. In ancient times, marriages were often arranged, and the union was considered a private and personal event, like the twilight of the evening. The 女 component indicates the subject of the action, a woman involved in the marriage.
