mdd -“Health, so if someone decides to start writing English using Hebrew script, but otherwise leave everything the same, it is going to be a new language? Ridiculous!”
First of all, Yiddish is Not just German with the Aleph -Bais. There are many differences.
Second of all, you said dialect. It can only be a dialect if it fits into one of the four definitions. Since it doesn’t have the same Alpha -Bet, it is a different language. This language might have come as an offshoot of German, but it isn’t German -it’s the only Jewish language right now. How come you think you are smarter than Gedolim for the last umteen years? They chose to speak in Yiddish over the languages of the countries where they resided in, this includes Ivrit, when they lived in EY. You don’t think they could learn a new language, esp. Ivrit which comes from Loshon Kodesh? The reason is because it’s (Yiddish) the Jewish language.
So stop with Yiddish is nothing more than German already.
