El Principinu — in Extremaduran language, a vernacular Romance dialects of the Asturleonese language spoken in Extremadura and adjoining areas in the province of Salamanca. I got this book directly from the translator, Antoniu Garrido Correas. Honestly, previously I know nothing about Extremadura. Then I realised that this area, together with Portugal, used to be the historical region of Lusitania.
