In addition to these, there are a number of seriously endangered and recognised minority languages: Aragonese, recognised, but not official, in Aragon. Asturian, recognised, but not official, in Asturias. Part of the Asturleonese language along Leonese and others. Leonese, recognised, but not official, in Castile and León. Spoken in the provinces of León and Zamora. Part of the Asturleonese language along Asturian and others. Spanish itself also has distinct dialects. For example, the Andalusian or Canarian dialects, each with their own subvarieties, some of them being partially closer to the Spanish of the Americas, which they heavily influenced to varying degrees, depending on the region or period and according to different and non-homogeneous migrating or colonisation processes. Despite being a dialect, some Andalusian speakers have attempted to promote Andalusian as a different language independent of Spanish. Five very localised dialects are of difficult filiation: Fala (a variety mostly ascribed to the Galician-Portuguese group locally spoken in an area of the province of Cáceres sometimes called Valley of Jálama/Xálima, which includes the towns of San Martín de Trevejo, Eljas and Valverde del Fresno); Cantabrian and Extremaduran, two Astur-Leonese dialects also regarded as Spanish dialects; Eonavian, a dialect between Asturian and Galician, closer to the latter according to several linguists; and Benasquese, a Ribagorçan dialect that was formerly classified as Catalan, later as Aragonese, and which is now often regarded as a transitional language of its own. Asturian and Leonese are closely related to the local Mirandese which is spoken on an adjacent territory but over the border into Portugal. Mirandese is recognised and has some local official status. Portuguese has been traditionally spoken by the inhabitants of the following border areas: Cedillo and Herrera de Alcántara (province of Cáceres), La Alamedilla (province of Salamanca, primarily spoken in the place up until the mid-20th century), and Olivenza (province of Badajoz). With the exception of Basque, which appears to be a language isolate, all of the languages present in mainland Spain are Indo-European languages, specifically Romance languages. Afro-Asiatic languages, such as Arabic (including Ceuta Darija) or Berber (mainly Riffian), are spoken by the Muslim population of Ceuta and Melilla and by recent immigrants (mainly from Morocco) elsewhere.
