While its origins are debated, Basque is considered a language isolate, meaning it's not related to any other known language family.
There are also smaller pockets of other non-Indo-European languages spoken in Southern Europe, including:
* Greek: While often considered part of the Indo-European family, it forms a separate branch, making it distinct from most other European languages.
* Turkish: Spoken by a significant minority in Cyprus and Greece.
* Arabic: Spoken by smaller communities in Spain, especially in Andalusia.
* Romani: A language spoken by the Roma people, found in various countries across Europe, including Southern Europe.
It's important to remember that while these languages are not Indo-European, they have all been influenced by the dominant Indo-European languages in the region, and their speakers have adopted many cultural practices and traditions from their Indo-European neighbors.
