CG, Ivrit is a living language, developing language. Many new words were indeed “invented” by scholars (their religious levels here are as irrelevant as the fact that the Ford Motor Company was founded by one of the more dastardly anti-Semites in American history). So too are all modern European languages as they contain words which were coined by scientists as they made discoveries (generally from Greek). English is a mix of French and German for historical reasons. Yiddish is a mix of Germanic and Slavic with some Hebrew as well as borrowings from other local languages (hence “American Yiddish”).
Moi aussi, I neither hate nor love Yiddish. It is for me a quaint relic to be dusted off when the great-aunt who gave it visits and then put back in the closet.
