Why “opsigamy” is a great word
Marriage contracted at an advanced age. From Ancient Greek ὀψέ (opsé, "late") + -γαμία (-gamía, "marriage"), from γάμος (gámos, "marriage"). Unlike "nubility," which denotes the youthful season for union, or "uxorilocal," which describes a residence custom, opsigamy is defined solely by the belatedness of its ceremony. It is the quiet registry-office wedding after decades of solitude, the deliberate merging of two sets of tarnished silverware, the soft weight of a well-worn hand finding its match—a pact made not in life's spring, but in its early winter, a defiance of chronology for the sake of settled companionship.
