Is Dravidian the source of Indo-European?
Indo-European Languages, the most widely spoken family of languages in the world (although not the largest language family in the world), containing the following nine subfamilies: Albanian, Armenian, Baltic, Celtic, Germanic, Greek, Indo-Iranian, Italic (including the Romance languages), Slavic; and five extinct subfamilies, Anatolian (including Hittite), Phrygian, Thracian, Tocharian, and an Unclassified group (including Venetic, which some linguists believe to be an Italic language). Indo-European languages were first spoken in Europe and southern Asia and, because of European colonialism, are now widespread throughout the world.
