Old Riojan

Old Riojan is an extinct variety of Navarro-Aragonese which was spoken in northeastern medieval La Rioja. This variety went extinct due to a rapid mixture with Castilian following La Rioja falling into the control of Crown of Castile.

Latin had been spoken in La Rioja after 218 BC, following the Second Punic War. These varieties eventually evolved into Old Riojan, and were first documented in the Glosas Emilianenses. In the modern day, the modern Riojan varieties of Castilian contain several characteristics which belonged to Old Riojan.
