Nusach (Jewish custom)

In Judaism, Nusach (Hebrew: נוסח, romanized: nusáḥ, Yiddish: נוסח, romanized: núsekh, plural נוסחים nusaḥim, Yiddish: נוסחאות, romanized: nuskhóes) is the exact text of a prayer service; sometimes the English word "rite" is used to refer to the same thing. Nusakh means "formulate" or "wording."

Texts used by different communities include Baladi-rite prayer, nusach Ashkenaz, nusach Sefard, nusach edot haMizraḥ, Italian Nusach and the nusach Ari.

A textual nusach is distinct from a musical one; the latter refers to a community's musical style or tradition, particularly the chant used for recitative prayers such as the Amidah.
