If all you know about the dreidel is that at one point someone made one out of clay and wrote a song about it, you would not be alone. Along with the menorah (or, to be more specific, the nine-armed hanukkiah used in the celebration of Hannukah) and the latke, the dreidel is one of Hannukah’s most recognizable symbols; it finds its way onto socks, cardboard cutouts, and sweaters.
