Joseph, ivrit is lashon hakodesh slightly distorted by an anti-religious man who used to put tefillin on a dog and let it run around Yerushalayim. It closely resembles real lashon hakodesh enough to be used as such if one leaves out the modern distortions like televizia. When one reads works like tha Alei Shur, one can see the results of such an effort. Its Hebrew is way more advanced than those of us non-Hebrew speakers are used to. Ben-Yehuda’s modern abominations and innovations do not cancel out thousands of years of Lashon Hakodesh. To say it does not resemble Lashon Hakodesh “in any way shape or form” is an admission that you don’t know Biblical, Mishnaic, or modern Hebrew well. Any perusal of a chumash with knowledge gleaned from a “hayesod” book will reveal the fact that they share more than they do not.
I will agree with you that usage of Yiddish for divrei kedusha made it holy, the way that Yaakov Avinu elevated simple stones of chullin into keilim of kedusha. The same thing applies to English, however. But does it retain its holiness when used for treif things? Are the works of Shalom Aleichem and other maskilim holy because they are in Yiddish? Does loshon hara said in a mikveh before davening in yiddish not count because it was spoken in an ersatz “looshin hakoidish”?
My brother-in law who lives in Kensington once visited me for shabbos, and he attended with me a shiur in English. after Shabbos, he expressed jealousy- where he lives, all the shiurim are in Yiddish, meaning he has no way of attending a shiur to improve his Torah knowledge on Shabbos. It’s hard enough for people to learn. Why throw up additional barriers and then wonder why they go off the derech?
But which Yiddish is holy? Is it the Lithuanian Yiddish or the Galician or Ungarshin yiddish? Is it more heilig to say “licht” or “lecht”? Is Lipa’s quote of the old marriage joke from kiddushin more or less heilig because he said “kaysif minoolin” instead of “kesef minalan”? does someone have “tzoros” or “tzooris”? Is your daughter Hinda or Henda? Is this Purim Toyrah, Purim Teyrah, or Pirim Toyrah?
Zei gebentched.
