The Hanukkah menorah, also chanukiah or hanukkiah is a nine-branched candelabrum lit during the eight-day holiday of Hanukkah, as opposed to the seven-branched menorah used in the ancient Temple or as a symbol. On each night of Hanukkah, a new branch is lit. The ninth holder, called the Shamash ("helper" or "servant"), is for a candle used to light all other candles or to be used as an extra light. To be kosher, the Shamash must be offset on a higher or lower plane than the main eight candles or oil lamps, but there are differing opinions as to whether all the lights must be arranged in a straight line, or if the channukiah can be arranged in a curve. The hanukkiah, along with the seven-branched menorah and the Star of David, is among the most widely produced articles of Jewish ceremonial.
