Sounds so German but the Jews from the series live in NY. Got a little confused. It is not Hebrew either.
I don't know the series
but German Jews used to speak Yiddish
it has a lot to do with German.
But is hardly spoken after the Second World War
because you reject German
Their ancestors probably come from Eastern Europe. Many of the Eastern European Jews spoke Yiddish.
Yiddish actually emerged from the old Middle High German because many Jews were expelled from Germany and found a new home in Eastern Europe.
That's why Yiddish sounds so German. Many words seem familiar to you.
? Funny post.
Yes confused and did not read his own link
