Necrophilia, also called thanatophilia and necrolagnia, is a paraphilia characterized by a sexual attraction to corpses. 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.
