Meaning

noun (Judeo-Christian and Islamic religions) chief spirit of evil and adversary of God; tempter of mankind; master of Hell

noun a planet (usually Venus) seen just before sunrise in the eastern sky

noun lighter consisting of a thin piece of wood or cardboard tipped with combustible chemical; ignites with friction

originFrom Middle English Lucifer, from Latin Lūcifer (from lūx (“light”) + ferō (“bear, carry”)). Attested in Old English as Lūċifer. Replaced native calque lēohtberend (“lightbearer”) also from the same Latin source. Application of the name to Satan results from what is probably a misinterpretation of Isaiah 14:12 (whence also the corresponding sense of morning star).
