demonology

Demonology functions as a technical term used in two primary contexts: academic theology/history and occultism. In an academic sense, it refers to the scholarly analysis of how different cultures or religions have conceptualized evil spirits and demons over time. In an occult context, it refers to the practical study of identifying, summoning, or banishing specific entities.

Because it ends in the suffix -ology, the word carries a formal, systematic connotation. It suggests a structured body of knowledge rather than mere superstition. It is rarely used in casual conversation unless the topic is specifically about religion, folklore, or fantasy world-building.

When compared to "exorcism," which is the active process of removing a demon, "demonology" is the theoretical framework and knowledge base that informs such practices. It is the study of the "what" and "why," whereas exorcism is the "how."
