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
Catalan shares many traits with the other neighboring Romance languages (Italian, Sardinian, Occitan, and Spanish). However, despite being spoken mostly on the Iberian Peninsula, Catalan has marked differences with the Iberian Romance group (Spanish and Portuguese) in terms of pronunciation, grammar, and especially vocabulary; showing instead its closest affinity with Occitan and to a lesser extent Gallo-Romance (French, Franco-Provençal, Gallo-Italian).
