Fur Shur, neither Sanskrit nor Greek got off the ground as written languages until the invention of writing, and that was by a non-Indo-European group that might even have Dravidian linguistic underpinnings. They are known as the Sumerians!
Interesting discussion - I’ve always heard that Sanskrit is a written and not a spoken language.
The Sumerian theory is fascinating. Isn’t cuneiform the earliest known form of nonideographic writing?
As for English in India, their need for a lingua franca which is also spoken worldwide, seems obvious.
I was deployed to Uzbekistan where the regime changed written Uzbek from cyrillic to the Latin alphabet, and replaced Russian in the schools with English as the second language.
To my mind, ever since blam told me about that, it seems so plausible, I'm just waiting for more archaeological proof. I already consider it true but not completely proven.
