Their Aragonese language, which might have been spoken in the whole of the Kingdom of Aragon, Kingdom of Navarre and La Rioja in the Middle Ages, is nowadays a seriously endangered language, natively spoken only by around 25,000 people in the northern mountain area of the autonomous community of Aragon.

[2] In 2009, the Aragonese language was recognized by the regional government as the "native language, original and historic" of Aragon, and it received several linguistic rights, such as use in public administration.

[5] Most Aragonese (90% or more) speak the Spanish language, traditionally in a northern variety with some regional traits, particularly in intonation and vocabulary.

The use of the native Aragonese language is now confined to a minority, mostly in rural and mountainous regions of northern Aragon.

In the easternmost areas, La Franja, varieties of the Catalan language are spoken by about 90% of the population.
