In my neighborhood, there used to be four large Orthodox congregations: Heights Jewish Center, Young Israel, Green Rd. Synagogue, and Chabad. There was also an ad hoc congregation that had begun in a home, called “Zichron Chaim.” It was commonly referred to as “the shteeble,” which is a Yiddish word for “little house” and refers to a small, organic, grass roots congregation, loosely formed and typically without a rabbi, that meets in a home and then sometimes, if it grows, migrates to a more spacious space.
