Mariticide

Mariticide (from Latin maritus "husband" + -cide, from caedere "to cut, to kill") literally means the killing of one's own husband. It can refer to the act itself or the person who carries it out. It can also be used in the context of the killing of one's own boyfriend. In current common law terminology, it is used as a gender-neutral term for killing one's own spouse or significant other of either sex. Conversely, the killing of a wife or girlfriend is called uxoricide.
