Castilian Spanish

This is because much of the variation in Peninsular Spanish is between north and south, often imagined as Castilian versus Andalusian.

[7] Typically, it is more loosely used to denote the Spanish spoken in all of Spain as compared to Spanish spoken in Latin America.

Castellano septentrional ("Northern Castilian") is the Spanish term for the dialects from the Northern half of Spain, including those from Aragón or Navarre, which were never part of Castile.

These dialects can be distinguished from the southern varieties of Andalusia, Extremadura, and Murcia.

[8] Español castellano, the literal translation of Castilian Spanish, is not a common expression; it could refer to varieties found in the region of Castile; however, the dialects of Castile, like other dialects, are not homogenous, and they tend to merge gradually with the dialects of other regions.
