Zarphatic, also called Judeo-French (Zarphatic: Tzarfatit) or Western Loez,[3] is a language that was spoken by the French Jews of northern France and in parts of west-central Germany, such as Mainz, Frankfurt am Main and Aix-la-Chapelle. It was also spoken by French Jews who moved to Norman England.[4] Some have conjectured that the language influenced the development of Yiddish.[5][6]
