In Mitzrayim, the Jews were rescued for three reasons (according to one midrash anyways):
They didn’t change a) clothes b)names and c) language.
A common argument for Yiddish. What i fail to understand is what makes ‘Yiddish’ into a Jewish language – Loshon HaKodes/Ivrit Tenachi is a Jewish Language. Yiddish is a collection of German, English, Loshon HaKodesh and a dozen other languages put together. Why is it Jewish?
