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
The word "Catalan" is derived from the territorial name of Catalonia, itself of disputed etymology. The main theory suggests that (Latin "Gathia Launia") derives from the name "Gothia" or "Gauthia" ("Land of the Goths"), since the origins of the Catalan counts, lords and people were found in the March of Gothia, whence "Gothland" > "Gothlandia" > "Gothalania" > "Catalonia" theoretically derived.
