If I understand correctly, both Litvaks and Chassidic people emphasized speaking Yiddish at home before WW2. What changed?
In today's age, why is Yiddish the primary language for Chassidim and not for Litvaks?
Why didn't Yeshivish people decide to continue ensuring the survival of the Yiddish language, like their Chassidic counterparts? (I understand that the shiur/class in many Yeshivish yeshivas is still taught in Yiddish; however, most of these students didn't grow up in a household that spoke Yiddish).
If there are any sources, that would be great.
