Why “cornutor” is a great word
CORNUTOR — [Noun] One who makes another person into a cuckold. From the Italian cornuto ("cuckold, horned one"), from the Latin cornūtus ("horned"), from cornu ("horn"). The suffix -or denotes an agent. First attested in English before 1675. Unlike "cuckold" (which denotes the betrayed husband) or "adulterer" (a general term for infidelity), a cornutor is the specific agent who imposes that disgrace. He is the shadow in the garden, the misplaced glove, the whispered punchline that hollows out a home—the architect of a private shame that is, in the end, a public landmark.
