A menorah, the Hebrew word for lamp, has seven branches. It was originally used in the First and Second Temples in Jerusalem. Menorahs were lit daily using olive oil of the purest quality. A hanukkiyah is a Hanukkah menorah used specifically to light the candles (often used today instead of oil) on Hanukkah. With nine branches, it is lit each night to celebrate the miracle of oil lasting eight days. Despite these differences, today hanukkiyahs are commonly referred to as menorahs.
