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.
I
don't know whats the work done by zvelebil and others quoted by Jyothi
Babu if
they could not trace what DRAVIDA means in Vedic Sanskrit.
India's
agony is there has been no national survey on scientific ground ( I am
not
using term linguistic ) done to understand relationship between the
languages
spoken in India.
