スベロアの公用語は何？
Soule's own language has been Basque for centuries, with the region featuring its own Souletin dialect. At the same time, the neighbouring Béarnais has been widely understood, and in recent centuries even spoken as a lingua franca. However, both Basque and Bearnese have lost ground to French with both languages struggling to survive into the next generation. Basque is attested to have been widespread farther east of the territory into the Pyrenees in previous centuries.
