Leonese is a set of certain vernacular Romance dialects that are spoken in northern and western portions of the historical region of León in Spain (modern provinces of León, Zamora, and Salamanca), and in a few adjoining areas in Portugal. In this narrow sense, Leonese is different from the dialects grouped under Asturian, though there is no clear division in purely linguistic terms. The current number of speakers of Leonese is estimated to be between about 20,000 and 50,000. The westernmost fringes of the provinces of León and Zamora belong to the territory of the Galician language, though there is dialectal continuity between the linguistic areas.
