Social Control through language

The so called "purity" of Sanskrit makes it a dead language, may be true, but that was the intention of the users, to safeguard their own supremacy over the masses. Nair exclaims:
"... The maintenance of the purity of Sanskrit language since the days of Panini until the present day is wonder of wonders that is largely to be explained by the tenacity of the Brahmin to preserve it as such, as the sacred language of status group even though their spoken language was, by and large, the local languages or a mixture of the two. This is not to admit that early Sanskrit before it reification did not borrow words from Dravidian languages and made them its own. As a matter of fact detailed research in the linguistic prehistory India is bound to reveal many instances for such a fusion of Tamil words into Sanskrit, especially that style of Sanskrit which came to be used for limited secular purposes."
