The Asturian language is the native language of Asturias. Between 200,000 and 600,000 people speak it in Asturias. This language is very similar to Leonese Language, spoken in other territories that once made up the Kingdom of León (León, Western Zamora, Salamanca and Northwestern Cáceres where is called extremaduran), and to Mirandes Language, spoken in Miranda do Douro in Portugal. In Asturias, primary and secondary students can choose to study it.
