A dreidel is a four-sided spinning top, played with during the Jewish holiday of Hanukkah.Each side of the dreidel bears a letter of the Hebrew alphabet: נ (Nun), ג (Gimel), ה (Hei), ש (Shin), which together means "a great miracle happened there" (referring to the miracle occurring in the land of Israel). Happy Hanukkah for all my Jewish customers and students!
