What does diabolology mean?
Diabolology is the formal study of the devil — a specialized branch of theology and religious scholarship concerned with the figure of Satan, his nature, his origins, and his role in religious belief. The term derives from Greek roots: diabolos, meaning 'slanderer' or 'accuser,' the word used for the devil in the Greek New Testament, combined with -logia, meaning 'study' or 'discourse.' While closely related to demonology, the broader field covering all demons and evil spirits, diabolology focuses specifically on the devil as a singular figure. The word is rare and decidedly academic in register, appearing mainly in theological treatises, historical analyses of witchcraft and heresy, and scholarly discussions of how concepts of evil developed within Christianity and related traditions. For readers interested in religious history, it offers a precise label for a surprisingly well-developed area of inquiry.
nounThe branch of theology or scholarship concerned with the devil, demons, and beliefs about evil spirits; the systematic study of the devil and demonology.
- The systematic study or scholarly treatment of the devil, especially within theology.

Etymology of diabolology
Diabolology comes from the Greek diabolos, meaning 'slanderer' or 'accuser,' which became the standard Greek term for the devil in the New Testament, joined to -logia, 'study' or 'discourse.' It entered English through post-classical Latin and scholarly usage, likely during the early modern period when systematic theological treatments of Satan flourished. It shares its root with words like diabolical and diabolism, and sits alongside demonology as a sibling discipline with a narrower focus.
How diabolology is actually used
A rare, learned term found chiefly in academic theology, religious studies, and historical scholarship. It carries no pejorative connotation itself and should not be confused with diabolism, which denotes devil-worship. Far less common than its sibling term demonology.
