Spanish Portuguese Jews developed Ladino which was taken after the inquisition over to Morocco, Babylonian Jews from Iraq use a type of Judeo-Arabic unique to Jews of that area.
Jerusalemites from old established families spoke Yiddish alongside Hebrew and Ladino, my own roots are from Yemin Moshe and my grandparents were sephardim who spoke Yiddish fluently. Post 1945 it was a way of making survivors feel welcome. Yiddish is a warm golden language which is part of our heritage, but must say German to my ears always sounds horrific
