Tamil is the oldest and purest of the four Dravidian languages. Ancient Indian literature is not all about the Vedas; itâ€™s about Sangam literature too. Tamil, the oldest and truest of the Dravidian speeches, boasts of this literary tradition of more than 2,200 years, the most remarkable body of secular poetry extant in India. While other pre-Aryan languages were happily courting Sanskrit and Prakrit (600 BC-600AD), Old Tamil stood firm in its corner refusing to yield. However, the evolutionary story of the language and script are a controversy among scholars even today.
