Word History

Etymology

Middle English, "the morning star, a fallen rebel archangel, the Devil," going back to Old English, borrowed from Latin Lūcifer "morning star," noun derivative of lūcifer "light-bringing, light-bearing," from lūc-, lūx "light" + -i- -i- + -fer -fer — more at light entry 1

Note: In patristic Latin Lūcifer was taken to be a name for the Devil of Christianity, based on the use of the word in the Vulgate rendering of Isaiah 14:12, where it translates Hebrew hêlēl, taken to mean "the shining one."

: devil entry 1 sense 1

Etymology

Old English Lucifer "the morning star, a fallen angel, the Devil," from Latin Lucifer "the morning star, bearer of light," derived from luc-, lux "light" and -fer "bearing"

Word Origin

What we sometimes call "the morning star" is really the planet Venus. The Romans called it Lucifer, meaning "bearer of light," because it appeared in the sky just before sunrise. So when, in the Old Testament, the prophet Isaiah says, in describing the downfall of the king of Babylon, "How are you fallen from heaven, O Morning Star, son of dawn," the "Morning Star" became Lucifer in the Latin translation. Early Christians thought that Isaiah was also referring to the devil, who had likewise "fallen from heaven." Thus the word Lucifer came to be applied to the devil.
