factoid about menorahs
A menorah is a candelabra, but is usually represented by the seven branched version that is described in the Torah. The Chanukiah has nine branches. One for the eight nights candles are lighted, and a branch for the shamus. A chanukiah is a menorah, but a menorah isn’t a chanukiah.
I didn’t know this till now – I thought the menorah was only for Hanukkah and had nine candles, one being the shamus to light the eight.
