Menachem > “דער עמעס”
the goal was to differentiate between Yiddish and Hebrew spelling so that those who learnt Yiddish would not be able to read Ivrit. I once talked to an elderly Yid from Odessa who just left USSR. He said that he – sadly – learned Yiddish as a kid but then communistim came and his cheder closed, and he wished to learn to read Ivrit all his life. I opened a chumash on the first page and ordered him: “read”. He read “bereshis bara …” and could not believe himself “I always was able to read Ivrit?!?”
This is like a moshal of a person who had a treasure buried in his yard his whole life but he was aware. Was he a rich man?
