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.
Catalan language
Western Catalan comprises the two dialects of Northwestern Catalan and Valencian; the Eastern block comprises four dialects: Central Catalan, Balearic, Rossellonese, and Alguerese. Each dialect can be further subdivided in several subdialects. The terms "Catalan" and "Valencian" (respectively used in Catalonia and the Valencian Community) are two varieties of the same language. There are two institutions regulating the two standard varieties, the Institute of Catalan Studies in Catalonia and the Valencian Academy of the Language in the Valencian Community.
