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.
Spanish naming customs
The Catalan-speaking territories also abide by the Spanish naming customs, yet usually the discrete surnames are joined with the word "i" ("and"), instead of the Spanish "y", and this practice is very common in formal contexts. For example, the former president of the Generalitat de Catalunya (Government of Catalonia) is formally called "El Molt Honorable Senyor Carles Puigdemont i Casamajó". Furthermore, the national language policy enumerated in article 19.1 of Law 1/1998 stipulates that "the citizens of Catalonia have the right to use the proper regulation of their Catalan names and surnames and to introduce the conjunction between surnames".
