Judeo-Latin

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. In the Middle Ages, there was no Judeo-Latin in the sense of "an ethnodialect used by Jews on a regular basis to communicate among themselves", and the existence of such a Jewish language under the Roman Empire is pure conjecture.
