Judaeo-Piedmontese

Judaeo-Piedmontese was the vernacular language of the Italian Jews living in Piedmont, Italy, from about the 15th century until World War II. It was based on the Piedmontese language, with many loanwords from ancient Hebrew, Provençal, and Spanish. Most of the speakers were murdered during the war, and as of 2015 it is virtually extinct.
