Which language is NOT Indo-European?

Hungarian is not an Indo-European language. It belongs to the Uralic language family, which is completely distinct from the Indo-European language family. While neighboring countries such as Slovakia, Romania, and Serbia have Indo-European languages, Hungary stands out with its unique linguistic roots. The origins of Hungarian can be traced back to the Ural Mountains in Siberia, and it shares linguistic similarities with languages spoken by indigenous peoples in northern Russia and Finland. Therefore, Hungarian is considered a non-Indo-European language due to its distinct linguistic heritage and its classification within the Uralic language family.
