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
However, some traits of the Spanish spoken in Spain are exclusive to that country, and for this reason, courses of Spanish as a second language often neglect them, preferring Mexican Spanish in the United States and Canada whilst European Spanish is taught in Europe. Spanish grammar and to a lesser extent pronunciation can vary sometimes between variants.
