Nusach Sefard

Nusach Sefard, Nusach Sepharad, or Nusach Sfard is the name for various forms of the Jewish siddurim, designed to reconcile Ashkenazi customs (Hebrew: מנהג "Custom", pl. minhagim) with the kabbalistic customs of Isaac Luria. 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. Each Hasidic dynasty uses its own version of the Nusach Sefard siddur, often with great divergence between different versions.

Some versions are nearly identical to Nusach Ashkenaz, while others come far closer to Nusach Edot Mizrach: most versions fall somewhere in between. All versions incorporate the customs of Isaac Luria.

Some non-Hasidic Ashkenazi synagogues, such as the Anshei Sefard synagogues, use this rite.

In 2012, Koren Publishers Jerusalem released the Koren Sacks Siddur in Nusach Sefard (Sepharad) in cooperation with the Orthodox Union. It features introduction, commentary and translation by Jonathan Sacks, the British Chief Rabbi. The Koren Sacks siddur is the only Orthodox siddur that includes prayers for the state of Israel, its soldiers and national holidays, a halakhic guide for visitors to Israel, a modern translation and transliteration, and citations of modern halachic authorities.

It is generally held that every Jew is bound to observe the mitzvot (commandments of Judaism) by following the customs appropriate to his or her family origin: see Minhag. For this reason a number of rabbis disapprove of the adoption of Nusach Sefard by Ashkenazi Jews.
