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.
