Leonese (llionés), in the narrow sense of this article, 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.
