Basque (Euskara) is a language isolate – the only surviving pre-Indo-European language in Western Europe, with no demonstrated relationship to any other known language family. According to Ethnologue, approximately 750,000 people speak Basque as a first language, concentrated in the Basque Autonomous Community and Navarre in northern Spain and in the French Basque Country (Pays Basque) in southwestern France. Euskara holds co-official status alongside Spanish in the Basque Autonomous Community and is recognized in parts of Navarre, making it a required language for government communications, legal proceedings, and public services in those jurisdictions. The standard written form (Batua, established in 1968) is used in formal, educational, and official contexts, while regional dialects including Bizkaian, Gipuzkoan, and Lapurdian remain in active use across different areas of the Basque Country.
