8. Basque
Basque is one of the language isolates that we decided to include in our list of 10 examples of isolated or extinct languages. The Basque language is not related to any other known language family today. It is spoken in small areas of France and Spain, but there are basque speakers throughout Europe and America, too. Speakers of Basque are usually bilingual and we cannot know the exact number of speakers due to lack of data.
