paragraph_text: Name of the language
  
  In Spain and some other parts of the Spanish-speaking world, Spanish is called not only español but also castellano (Castilian), the language from the Kingdom of Castile, contrasting it with other languages spoken in Spain such as Galician, Basque, Asturian, Catalan/Valencian, Aragonese, Occitan and other minor languages.
  
  The Spanish Constitution of 1978 uses the term castellano to define the official language of the whole of Spain, in contrast to las demás lenguas españolas (lit. "the other Spanish languages "). Article III reads as follows:
  
  El castellano es la lengua española oficial del Estado.... Las demás lenguas españolas serán también oficiales en las respectivas Comunidades Autónomas... Castilian is the official Spanish language of the State.... The other Spanish languages shall also be official in their respective Autonomous Communities...
  
  The Royal Spanish Academy (Real Academia Española), on the other hand, currently uses the term español in its publications. However, from 1713 to 1923, it called the language castellano.
  
  The Diccionario panhispánico de dudas (a language guide published by the Royal Spanish Academy) states that, although the Royal Spanish Academy prefers to use the term español in its publications when referring to the Spanish language, both terms— español and castellano —are regarded as synonymous and equally valid.
