Necrophilia, also calle thanatophilia and necrolagnia, is the sexual attraction to corpses. It is classified as a paraphilia by the Diagnostic and Statistical Manual of the American Psychiatric Association. The word is artificially derived from Ancient Greek: νεκρός (nekros; "corpse," or "dead") and φιλία (philia; "love"). The term appears to have originated from Krafft-Ebing's 1886 work Psychopathia Sexualis.
