What is a dreidel and what are the four signs on it and what do the four letters spell out?
What is a small four-sided spinning top with a Hebrew letter on each side.
Each side of the dreidel bears a letter of the Hebrew alphabet: נ (Nun), ג (Gimel), ה (Hei), ש (Shin), which together form the acronym for "נס גדול היה שם" (Nes Gadol Hayah Sham – "a great miracle happened there").
