Languages of Catalonia
There are four languages with official status in Catalonia (an autonomous community of Spain): Catalan; Spanish- which is official throughout Spain; Aranese, a dialect of Occitan spoken in the Aran Valley; and Catalan Sign Language. Many other languages are spoken in Catalonia as a result of recent immigration from all over the world.
Valencian Community
Spanish (Castilian or "castellano") has official status in all of Spain, including the Valencian Community. Aside from it, the Statute of Autonomy recognizes Valencian as the language proper to the Valencian people ("llengua pròpia"), and commends its protection and regulation to the Acadèmia Valenciana de la Llengua (AVL) under the Generalitat Valenciana. Valencian is also official in the autonomous communities of Catalonia and the Balearic Islands, where it is called Catalan.
