Whats “yiddish”?
You mean “lashon Ashkenaz”?
Or “Teitch”?
Ok. But I never heard of yiddish…… The anti religious and anti “Semitic” jews, made that up.
Agav, the ת being pronounced as a S goes back to Aramaic times, where they pronounced ת like ש S, hence they used ת and ש interchangeably.
Also the Greco Roman “S”, which makes plurality, comes from the Hebrew ת, even though they could pronounce “th”, they still said “S” for plurality, because that’s they way it was pronounced back then.
I used to think it was German mis- pronunciation, but the ת and ש being swapped in Aramaic is a very strong proof.
