the Debreciner Rav ZL was asked about about english and he replied that our “Yeshivishizing” english suffices to fulfill what the Chasam Sofer wanted. We borrow many expressions from Yiddish, Aramaic (as in l’chorah, memaileh etc) and Hebrew (like mamsh), as well as changing the usage and syntax (The usage of the word “by” in “I was by so-and-so for Shabbos” does not happen in the English language).
