Castilian is the official language of Spain and all the countries that have been colonized by Spain (Almost all the Latin American countries). The term 'Spanish' is a slip-up. In Castilian itself, it is named "Castellano". It is the same language spoken in Spain (just different accent). You oughtn't forget that 4 languages are spoken in Spain (Spanish languages) which are Castilian (Official one) Galician, Catalan, and Basque.
