Nusach Sefard, Nusach Sepharad, or Nusach Sfard is the name for various forms of the Jewish siddurim, designed to reconcile Ashkenazi customs with the kabbalistic customs of Isaac Luria.[1] To this end it has incorporated the wording of Nusach Edot haMizrach, the prayer book of Sephardi Jews, into certain prayers. Nusach Sefard is used nearly universally by Hasidim, as well as by some other Ashkenazi Jews, but has not gained significant acceptance by Sephardi Jews. Some Hasidic dynasties use their own version of the Nusach Sefard siddur, sometimes with notable divergence between different versions.
