Linguistic rights
Spanish language is the stated to be the official language of Spain in Article 3 of the Spanish constitution, being the learning of this language compulsory by this same article. However, the constitution makes provisions for other languages of Spain to be official in their respective communities. An example would be the use of the Basque language in the Basque Autonomous Community (BAC). Apart from Spanish, the other co-official languages are Basque, Catalan and Galician.
