Spanish language
The Spanish word for Spanish is "español", and the Spanish word for Castilian is "castellano". In the other Romance languages spoken on the Iberian Peninsula, such as Galician, Catalan, Asturian, and others, Spanish is usually called "Castellán" or "Castellà" instead of "Spanish". In Spain, the name of the subject in schools is "lengua castellana" (Castilian language). However, in the regions of Spain in which people speak only Spanish, people call their language Spanish.
