Sanskrit, as we know it, is not the original Vedic language.
SansKrit as the name signifies is a reformed language.
Samskara=to reform or clean up.
The Old Vedic language is Deva-Bhasha the language of the Gods (Deva).
Panini, a scholar cleaned up the very complex grammer and simplified it into Sanskrit. SansKrit as a language is very scientific, its almost mathematical! If you mixup randomly all the words in a Sanskrit sentence, it will still mean the same! The phonetic speech sounds in Sanskrit also rise and fall in perfect musical rhythm, accurate to the minutest degree. All verses constructed in Sanskrit are bound in a particular metre and a rhythm by the author. This is called Chhanda.

So, Veda was not spoken like random speech.
Rather, it was sung! People communicated in songs, with melody!
