Basque is related to no other language on Earth
Spanish, French, English, Russian and Hindi are all distant cousins. Basque, spoken between Spain and France, is no one’s cousin at all.
Most languages of Europe belong to one huge family, Indo-European: English, Spanish, Russian, Greek and Hindi all descend from a common ancestor spoken thousands of years ago. A few belong to other families, like Finnish and Hungarian (Uralic).
Basque belongs to none. It is a language isolate: linguists have never demonstrated a relationship with any other language. It is the only one in Europe.
Where it comes from
The leading explanation is that Basque is older than its neighbours. It probably descends from languages spoken in western Europe before Indo-European languages arrived. Inscriptions from Roman-era Aquitaine contain names that look like early Basque.
Over the years people have tried to link it to Georgian, Berber, Etruscan and even the Picts. None of these theories has convinced most specialists.
Small but stubborn
A 2021 survey counted about 806,000 speakers, around 94% of them on the Spanish side. Basque was suppressed under Franco, and has since been revived through Basque-medium schools called ikastolak.
Even Spanish carries a trace of it: the word for left, izquierda, is widely thought to come from Basque ezker. In Basque, the language is called euskara.

Bring it up
“Basque has no known relatives at all. It may be the last survivor of the languages Europe spoke before Latin and Celtic arrived.”
