Dear Manju, The earlier form of Kannada was a product of Proto-Tamil and Prakrit but not certainly sanskrit. Morover, The Brahmi script that Kannada uses is certainly a form of Tamil Brahmi which evolved from "Vettazhuthu". Tholkappium is based on this "Vettazhuthu". sanskrit borrows the grammer from Prakrit text of Panini. So dont be carried by false claims. You are more closer to Tamil than to Sanskrit.
