Panini was a Sanskrit grammarian who gave a comprehensive and scientific theory of phonetics, phonology, and morphology.
Sanskrit was the classical literary language of the Indian Hindus and Panini is considered the founder of the language and literature.
The word "Sanskrit" means "complete" or "perfect" and it was thought of as the divine language, or language of the gods.
He was born in Shalatula, a town near to Attock on the Indus river in present day Pakistan.
He lived somewhere between the 4th and 7th century BC.
There is also no agreement among historians about the extent of the work which he undertook and how much of it was his own innovation.
What is in little doubt is that, given the period in which he worked, he is one of the most innovative people in the whole development of knowledge.
