A demon is a supernatural being, often malevolent, that appears in the religious traditions, mythologies, and literatures of the world. The term originates from the Ancient Greek word daimon (δαίμων), which can also mean "spirit" or "god." In Hebrew, the equivalent term is shed (שד), which can refer to a demon or evil spirit. In Arabic, the term is shaytan (شيطان), which can also mean "Satan" or "devil." Demons are often depicted as agents of evil, tempters, or tricksters, and they are frequently associated with possession, temptation, and various forms of malevolent activity. The concept of demons is prevalent in Abrahamic religions, including Judaism, Christianity, and Islam, as well as in various other religious and mythological traditions around the world. In many traditions, demons are believed to be fallen angels, spirits of the dead, or entities that exist to oppose divine will and tempt humans into sin or wrongdoing.
