Venus is a Latin word. No need for translation. In Latin, the the morning star was often called Phosphorus. Another name for that was Lucifer. But that does not necessarily mean Venus = Lucifer or Lucifer = Venus.
"Like the planet Mercury, Venus was known in ancient Greece by two different names—Phosphorus (see Lucifer) when it appeared as a morning star and Hesperus when it appeared as an evening star. Its modern name comes from the Roman goddess of love and beauty (the Greek equivalent being Aphrodite), perhaps because of the planet’s luminous jewel-like appearance."

"Lucifer, (Latin: Lightbearer) Greek Phosphorus, or Eosphoros, in classical mythology, the morning star (i.e., the planet Venus at dawn); personified as a male figure bearing a torch, Lucifer had almost no legend, but in poetry he was often herald of the dawn. In Christian times Lucifer came to be regarded as the name of Satan before his fall. It was thus used by John Milton (1608–74) in Paradise Lost, and the idea underlies the proverbial phrase “as proud as Lucifer.” ""
