Judeo-Latin (also spelled Judaeo-Latin) is the use by Jews of the Hebrew alphabet to write Latin.
[2] The term was coined by Cecil Roth to describe a small corpus of texts from the Middle Ages.
[2] 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.
[3] The Judeo-Latin corpus consists of an Anglo-Jewish charter and Latin quotations in otherwise Hebrew works (such as anti-Christian polemics,[4] incantations and prayers).
[2] Christian converts to Judaism sometimes brought with them an extensive knowledge of the Vulgate translation of the Bible.
