Spanish

Spaniards,[a] or the Spanish people, are a Romance[26] ethnic group that are indigenous to Spain. They 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 Kingdom of Castile in north and central Spain. Historically, the Spanish people's heritage includes the pre-Celts and Celts (Celtiberians, Lusitanians, Gallaecians, Oestriminis, Turduli and Celtici).
