Basque ( in Basque : Euskara ) is the language spoken by the Basque people in the Basque Country and diaspora . Today Basque holds co-official language status in the Basque regions of Spain : the full autonomous community of the Basque Country and some parts of Navarre . Basque has no official standing in the Northern Basque Country of France and French citizens are barred from officially using Basque in a French court of law .
