Asturleonese

Asturleonese is a Romance language or language family spoken in northwestern Spain and northeastern Portugal, namely in the historical regions and Spain's modern-day autonomous communities of Asturias, northwestern Castile and León, Cantabria and Extremadura, and in Riudenore and Tierra de Miranda in Portugal. The name of the language is largely uncommon among its native speakers, as it forms a dialect continuum of mutually intelligible varieties and therefore it is primarily referred to by various regional glossonyms like Leonese, Cantabrian, Asturian or Mirandese (in Portugal). Extremaduran is sometimes included as well. Asturleonese has been classified by UNESCO as an endangered language, as the varieties are being increasingly replaced by Spanish and Portuguese.

Phylogenetically, Asturleonese belongs to the West Iberian branch of the Romance languages that gradually developed from Vulgar Latin in the old Kingdom of León. The Asturleonese group is typically subdivided into three linguistic areas (Western, Central and Eastern) that form the vertical Asturleonese region, from Asturias, through León, to the north of Portugal and Extremadura. The Cantabrian Montañes in the East and Extremaduran in the South have transitional traits with Spanish (northern Spanish for Cantabrian, southern Spanish for Extremaduran). There are differing degrees of vitality of the language for each region in the area: Asturias and Miranda do Douro have historically been the regions in which Asturleonese has been the best preserved.
