Autonomous communities of Spain
Spanish legislation, most notably in the Statutes of Autonomy of the bilingual communities, use the term "own language", or "language proper to a community", to refer to a language other than Spanish that originated or had historical roots in that particular territory. The Statutes of Autonomy of the respective autonomous communities have declared Basque the language proper to the Basque Country and Navarre, Catalan the language proper to Catalonia, the Balearic Islands and the Valencian Community—where it is historically, traditionally and officially known as Valencian—and Galician to be the language proper to Galicia. There are other protected regional languages in other autonomous communities. As a percentage of total population in Spain, Basque is spoken by 2%, Catalan/Valencian by 17%, and Galician by 7% of all Spaniards. A 2016 Basque Government census revealed 700,000 fluent speakers in Spain (51,000 in Basque counties in France) and 1,185.000 total when passive speakers are included.
Peninsular Spanish
Peninsular Spanish (), also known as Spanish of Spain () European Spanish () and Iberian Spanish (), sometimes inaccurately referred to as Castilian Spanish () refers to the varieties of the Spanish language spoken in the Iberian Peninsula, as opposed to the Spanish spoken in the Americas and in the Canary Islands. The related term Castilian Spanish is often applied to formal varieties of Spanish as spoken in Spain. According to folk tradition, the "purest" form of Peninsular Spanish is spoken in the Castilian province of Valladolid, although the concept of "pure" language has been questioned by modern linguists.
