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.
Castilian Spanish
The term "Castilian Spanish" can be used in English for the specific varieties of Spanish spoken in north and central Spain. Sometimes it is more loosely used to denote the Spanish spoken in all of Spain as compared to Spanish spoken in Latin America. There are several different varieties of Spanish, which should not be confused with the other official and non-official languages in Spain, of which Castilian is only the most prominent because it is the only one that is official throughout the whole national territory.
