THE politics of nomenclature may finally end in Tamil Nadu with the DMK government going in for largescale renaming in a bid to stop the ongoing caste violence in its southern districts.

Thus, Anna and Periyar districts, named after prominent leaders of the Dravidian movement, are now rechristened Dindugal and Erode respectively.
