Judeo-Latin (also spelled Judaeo-Latin) is the use by Jews of the Hebrew alphabet to write Latin. The term was coined by Cecil Roth to describe a small corpus of texts from the Middle Ages.
Usage
The Judeo-Latin corpus consists of an Anglo-Jewish charter and Latin quotations in otherwise Hebrew works (such as anti-Christian polemics, incantations and prayers).
