Children nowadays are taught sherashim – lashhon kodesh at a pretty young age.
To the issue at hand, I very much believe in a project started recently called “Aleh” or something like it – to train Rebbeim and teachers how to convey material with a “Geshmack”, how to pump a joyful zest and “bren” into Yiddishkeit. A pleasurable enjoyment enough to counteract the other “pleasures”. It has the backing of Gedolim. (and no, I have nothing to do with it)
