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.
Linguistic features of Spanish as spoken by Catalan speakers
The Spanish language is widely spoken in most of the Catalan-speaking territories, where it is partly characterized by language contact with the Catalan language. These territories are: Catalonia, the Valencian Community (except some inland areas which are only Spanish-speaking), the Balearic Islands, Andorra, and the easternmost areas of Aragon. This linguistic contact is encouraged by the fact that almost all of the Catalan speakers in these regions are Catalan–Spanish bilingual to a greater or lesser extent.
