Lucifer is another name for Satan. This is because people interpret a passage in the Book of Isaiah of the Bible in a certain way. Lucifer is Latin. It is made of two parts, lux-lucis (light) and ferre (to bring).There are two mentions of Lucifer in the Latin Vulgate. is used to refer to the morning star, the planet Venus that appears at dawn: once in 2 Peter 1:19 to translate the Greek word "Φωσφόρος" (Phosphoros), which has exactly the same literal meaning of "Light-Bringer" that "Lucifer" has in Latin; and once in Isaiah 14:12 to translate "הילל" (Hêlēl), which also means "Morning Star".
