Spanish language
In Spain and in some other parts of the Spanish-speaking world, Spanish is called not only (Spanish) but also (Castilian), the language from the kingdom of Castile, contrasting it with other languages spoken in Spain such as Galician, Basque, Asturian, Catalan, Aragonese and Occitan.
Basque language
The Spanish Constitution of 1978 states in Article 3 that the Spanish language is the official language of the nation, but allows autonomous communities to provide a co-official language status for the other languages of Spain. Consequently, the Statute of Autonomy of the Basque Autonomous Community establishes Basque as the co-official language of the autonomous community. The Statute of Navarre establishes Spanish as the official language of Navarre, but grants co-official status to the Basque language in the Basque-speaking areas of northern Navarre. Basque has no official status in the French Basque Country and French citizens are barred from officially using Basque in a French court of law. However, the use of Basque by Spanish nationals in French courts is permitted (with translation), as Basque is officially recognised on the other side of the border.
