Names of demons originating in Abrahamic faith traditions include Satan, Lilith, Beelzebub and Moloch. Other demons' names include Mara, from Buddhism, and Tlaltecuhtli, from Aztec mythology.
Satan is the most significant demon in Christianity, Judaism and Islam. The name Satan derives from a root meaning "to oppose" or "to act as an adversary." In the Quran, the Devil goes by the names Shaitan, which shares the same root as Satan, and Iblis, which probably derives from the Greek term "diabolos," meaning "slanderer."
Lesser demons in the Abrahamic tradition include Lilith, Beelzebub and Moloch. Lilith is a female demon sometimes considered Adam's first wife before Eve. The Hebrew name Lilith means "night monster."
Beelzebub is a Philistine god that the Bible characterizes as a demon. The name "Beelzebub" means "lord of the flies." Moloch is a Phoenician god worshipped by idolatrous Israelites and associated with child sacrifice. His name means "king."
Mara is the evil spirit in Buddhism who tempted Siddhartha as he sat beneath the Bodhi Tree. "Mara" means "death" or "thirst." Other names for Mara include Papiyan, which means “more wicked,” and Varsavarti, which means “he who fills desires.”
In Aztec mythology, Tlaltecuhtli is an Earth monster with many mouths. Although it is usually depicted as a female demon, Tlaltecuhtli's name means "Earth Lord."
