Languages of Catalonia
According to the government of Catalonia, Spanish, locally known as Castilian, is currently the most spoken language in Catalonia (45.9% daily users of Spanish vs. 35.6% daily users of Catalan vs. 11% daily users of both Spanish and Catalan) and especially in the Barcelona metropolitan area, as well as native language and usual language of many Catalan citizens. This language is widely prevalent in the press, cinema and in daily life.
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".
