Aragonese (/ˌærəɡəˈniːz/ ARR-ə-gə-NEEZ; aragonés [aɾaɣoˈnes] in Aragonese) is a Romance language spoken in several dialects by about 12,000 people as of 2011, in the Pyrenees valleys of Aragon, Spain, primarily in the comarcas of Somontano de Barbastro, Jacetania, Alto Gállego, Sobrarbe, and Ribagorza/Ribagorça. It is the only modern language which survived from medieval Navarro-Aragonese in a form distinct from Spanish.
Historically, people referred to the language as fabla ('talk' or 'speech'). Native Aragonese people usually refer to it by the names of its local dialects such as cheso (from Valle de Hecho) or patués (from the Benasque Valley).
Ribagorza (Spanish: [riβaˈɣoɾθa], Aragonese: [ɾiβaˈɣoɾθa]) or Ribagorça (Western Catalan: [riβaˈɣɔɾsa]; French: Ribagorce) is a comarca (administrative subdivision) in Aragon, Spain, situated in the north-east of the province of Huesca. It borders the French département of the Haute-Garonne to the north and Catalonia (the comarques of Val d'Aran, Alta Ribagorça, Pallars Jussà, and Noguera) to the east. Within Aragon its neighboring comarcas are Sobrarbe, Somontano de Barbastro, and La Litera. It roughly corresponds to the Aragonese part of the medieval County of Ribagorza. The administrative capital of Ribagorza is Graus, although the historical capital of the county was at Benabarre.
The Ribagorçan dialect is a transitional Aragonese–Catalan dialect spoken in the western part of the comarca. Municipalities in the eastern part, bordering Catalonia, are part of La Franja, a geolinguistic area, where the local language is a variety of Catalan. However, Aragonese and Catalan form a dialect continuum here and the geographical limit of both languages cannot be drawn in a clear-cut manner.
La Litera (Spanish: [la liˈteɾa]) or La Llitera (Catalan: [la ʎiˈteɾa]) (Aragonese: A Litera) is an Aragonese comarca in the south-east of the province of Huesca.
Its cultural capital is Tamarite de Litera, its administrative capital is Binefar and it borders the comarques of Ribagorza, Somontano de Barbastro, Cinca Medio, Bajo Cinca in Aragon and Noguera and Segrià in Catalonia.
