      Alternative Spellings



  • According to Gold, the pronunciation of kosher in American English is influenced by the [ow] vowel of "American Western Ashkenazic English," which was spoken by Jews from Germany and/or other western parts of Ashkenaz after immigration to the United States (David Gold, "Jewish English," in J. A. Fishman (ed.), Readings in the Sociology of Jewish Languages. Leiden: Brill. 280-298). British Jewish English uses the [ɔ] vowel from Northeastern Yiddish.
