Leonese (, ) is a set of vernacular Romance language varieties currently spoken in northern and western portions of the historical region of León in Spain (the modern provinces of León, Zamora, and Salamanca) and a few adjoining areas in Portugal. In this narrow sense, Leonese is distinct from the dialects grouped under the Asturian language. There is no real linguistic division, though; it is only a purely political and identitary division, as dialectal areas (western, central, eastern...) are in fact shaped along a north-south axis (thus encompassing lands both north and south of the mountains, both in Asturias and in Castile and León). In the past, it was spoken in a wider area, including most of the historical region. The current number of Leonese speakers is estimated at 20,000 to 50,000. The westernmost fringes of the provinces of León and Zamora are in the territory of the Galician language, although there is dialectal continuity between the linguistic areas. The Leonese and Asturian dialects have long been recognized as a single language, currently known as Astur-Leonese or Asturian-Leonese. Sometimes the language as a whole is simply called "Asturian" because of several reasons, such as the Leonese dialects being on the brink of extinction, or the widespread ignorance of its very existence (even in León), as well as their lack of recognition and institutional support (as opposed to their Asturian counterparts). On the other hand, Menéndez Pidal and fellow scholars discussed a "Leonese language" descending from Latin and encompassing two groups: the Asturian dialects on one hand, and dialects spoken in the provinces of León and Zamora in Spain and a related dialect in Trás-os-Montes (Portugal), on the other hand. Unlike Asturian, which is regulated by the Academy of the Asturian Language (ALLA) and promoted by the Asturian Government and local legislation, the Leonese dialects are not officially promoted or regulated. Moreover, the Asturleonese dialect (considered part of the Leonese dialects) of Miranda do Douro (Portugal), Mirandese, is most certainly a dialect on its own, considering the numerous differences it has when compared to dialects in the Spanish side. In fact, it is often considered as a separate language, especially in Portugal, where it is an official language along with Portuguese and it is regulated by the Institute of the Mirandese Language. Thus, Asturleonese is sometimes considered a group of two languages, Asturian or Asturleonese proper, and Mirandese. Name Menéndez Pidal
