I must admit I find it a bit ironic that many Jews in America keep alive a Germanic language - Yiddish. Wouldn’t it make sense to switch to Hebrew?
That is why the state of Israel schooled all of the original citizens from the post WWII Exodus to learn Hebrew.
Yiddish is the lingua franca of New York City. A wonderfully soulful and colorful language that is being lost in the west and practically wiped out in Israel (I stand to be corrected on that point). Also getting lost is the food of Jewish Eastern Europe as “healthy” Shepardic and Israeli stuff is getting popular. I don’t think it is a patch on the delicious, hardy foods that I grew up with. Hummus! Yuck!
