“Hanukkah gelt” is an unusual expression in American Jewish speech. Apart from the Orthodox, such Yiddishisms aren’t commonly employed in English for Jewish religious practices and customs. Orthodox Jews may go to “shul,” but most other Jews go to synagogue or temple. The former “daven,” the latter pray. The more punctiliously observant speak of “Likhtbentshn”; for the less rigorous, it’s candle lighting. Yet who says “Hanukkah money”?
