Dear Mr.Lalit Mishra
Could you pl explain the reason behind and origin of the word Bharani nakshatra (Star cluster) without referring Puranic, Akhanda Bharata, Proto Indo European language, Proto-Sanskrit and other speculative theories (non est), before Claiming that Tamil borrows all the names of nakshtras, rashish and planets from Sanskrit.
Could you pl check the words द्रविडः draviḍaḥ, द्राविडः drāviḍaḥ in your Sanskrit dictionaries or Proto Indo European dictionaries before claiming that there has been no Dravida language in the times Vedas were being re-organized, Since, In the Vedas, "DRAVIDA" is name given to "God Agni".
You have confessed that Tamil is shaped as an Independent language. you pl remember that the grammars of Tamil and Sanskrit languages are totally different. For e.g vibhakti (cases), gender, numbers, etc. Even vibhaktis of Hindi and Sanskrit languages are totally different. Unlike Sanskrit, Tamil is living classical language. Pl study Tholkappiyam before commenting that Tamil has borrowed grammar rules from "Divine language(?)" Sanskrit.
with kind regards
