Why “mariticide” is a great word
MARITICIDE — [Noun] The act of killing one's spouse, especially the murder of a husband by his wife; also, a woman who has killed her husband. From Latin maritus ("husband") + -cide (from Latin caedere, "to kill"). Unlike "uxoricide," which designates the killing of a wife, or the generic "homicide," mariticide precisely names the severing of the most intimate social contract by the hand that pledged to cherish it. It is the arsenic in the evening cordial, the blade drawn in the shared bedroom, and the cold weight of a wedding ring left on a nightstand—a private apocalypse that inverts the sacrament of trust into a lethal, final ceremony.
