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.
Names given to the Spanish language
In the regions where regional languages are spoken, there is obviously a daily need to make the contrast between the national language and the regional language and so the national language is most often referred to as Castilian, particularly in the regional languages themselves (for example, "espanyol" is virtually never used to refer to the language in Catalan: "castellà" is used instead; in Basque, the name of the language is "gaztelania" or "gaztelera", never "espainiera"; and in Galician, the most commonly used term is "castelán" rather than "español"). That is often mirrored by educated English-speakers to refer to the linguistic situation in Spain.
