A historically rich Jewish language that contributed numerous loanwords to English and reflected Jewish cultural history, replaced by Hebrew in Israel.
"My bubbe and zayde proudly spoke Yiddish, not Hebrew. They regarded Yiddish as the Jewish language and Hebrew as a language used only in religious contexts. They spoke Yiddish, Ukrainian, Russian, and sometimes even tried to speak English, but Hebrew was for prayers only."
"jews had an awesome language that contributed such great loanwords as "schmaltzy" & "schmuck" & "schlong" & "schlock" & was a tangible reflex of their history as a people. now they all speak a glorified conlang. why? this sucks"
