Basque (/bæsk, bɑːsk/;[1] euskara [eus̺ˈkaɾa]) is a pre-Indo-European language spoken in the Basque Country, extending over a strip along eastern areas of the Bay of Biscay in Spain and France, straddling the western Pyrenees. It is classified as a language isolate, having no demonstrable genetic relation to any other known language, with the sole exception of the extinct Aquitanian language, which is considered to be an ancestral form of Basque.[2][3]
