Lucifer, << LOO suh fuhr, >> is a name commonly used for the devil. It was originally a Latin word meaning light bearer. The word comes from a Latin translation of a Hebrew term from Isaiah, which means shining one. It appears in Isaiah 14:12: “How you have fallen from the heavens, O shining one, son of morning!”
Isaiah applied the name shining one or Lucifer to a king of Babylon. But it came to be thought of as an evil archangel who was hurled from heaven for his wickedness and revolt against God. The word also refers to the planet Venus as the morning star.
