1. Korean
Korean is by far a language isolate with the greatest number of speakers so we decided to put it in the first place on our list of 10 examples of isolated or extinct languages. Actually, it was considered a language isolate but in recent times some linguists tend to believe that Korean is linked to a family of languages called the Altaic language family, but as this issue is still not resolved due to many existing theories, for many Korean remains a language isolate with a total number of speakers of around 77 million throughout the world.
