Sanskrit was the language of Greater India, Vedic India (same
thing), and Greater Iran. It was the language of the Vedas. It was
closely tied with its counterpart, Avestan, the official language
of Greater Iran and the Avesta. Sanskrit is still spoken today in
India, numbering in about 10,000 active, fluent speakers. It
originated before the Mahajanapada times of Ancient India. It was
first used for Vedic culture, which again, sprouted in Greater
India (composite of today's North India, Pakistan, and
Afghanistan).
