Dravidian languages theory

The Dravidian languages theory suggests that many languages spoken mainly in southern India and parts of Pakistan, Sri Lanka, and Bangladesh share a common ancestral language called Proto-Dravidian. Linguists study similarities in vocabulary, grammar, and sounds among these languages—like Tamil, Telugu, Kannada, and Malayalam—to trace their roots back to this ancient language. The theory helps explain how these languages are related and evolved over thousands of years, providing insight into the cultural and historical connections of the Dravidian-speaking peoples.
