As Ashkenazi Jews moved away from Europe, mostly in the form of aliyah to Israel, or immigration to North America, and other English-speaking areas; and Europe (particularly France) and Latin America, the geographic isolation that gave rise to Ashkenazim has given way to mixing with other cultures, and with non-Ashkenazi Jews who, similarly, are no longer isolated in distinct geographic locales. Hebrew has replaced Yiddish as the primary Jewish language for many Ashkenazi Jews, although <answer>many Hasidic and Hareidi groups</answer> continue to use Yiddish in daily life. (There are numerous Ashkenazi Jewish anglophones and Russian-speakers as well, although English and Russian are not originally Jewish languages.)
What two groups continue to use Yiddish in daily life?
many Hasidic and Hareidi groups
