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.
Spaniards
Spaniards are a Romance ethnic group and nation. They are indigenous to Spain and share a common Spanish culture, history, ancestry, and language. Within Spain, there are a number of nationalisms and regionalisms, reflecting the country's complex history and diverse culture. Although the official language of Spain is commonly known as "Spanish", it is only one of the national languages of Spain, and is less ambiguously known as Castilian, a standard language based on the medieval romance speech of the early Kingdom of Castile in north-central Spain and the Mozarabic dialect of the Taifa of Toledo which was incorporated by the former in the 11th century. There are several commonly spoken regional languages, most notably Basque (a Paleohispanic language), Catalan and Galician (both Romance languages like Castilian). There are many populations outside Spain with ancestors who emigrated from Spain and who share a Hispanic culture; most notably in Hispanic America.
