既婚
きこん · kikon · JLPT N1 · na-adj
married
💍 既 (already) + 婚 (marriage): already tied in marriage, so 'married' is the already-done state
既 means 'already' or 'finished', and 婚 means 'marriage'. Together they describe the state of marriage that has already happened. Compare 未婚 (mi-kon), 'not yet married'.
既 — 皀 (food vessel) + 旡 (person turning away)
Originally a pictograph of a person turning away from a food vessel, signaling a finished meal. From this came the meanings 'already' and 'completed.' The modern sense 'since' or 'now that' developed by extension from the idea of an action already done.
