Panini was an eminent Sanskrit grammarian of ancient India. He is believed to have codified the Sanskrit grammar using just under 4000 ‘sutras’ (rules). His notable contribution includes detailed and scientific theory of phonetics, phonology and morphology.
Panini’s major work is Astadhyayi (Astaka), which provides a differentiation between the language used in scriptures and the language used by the people for communication. The basic grammar elements of Sanskrit are classified in this book. The rules involved in the construction of sentences are explained in detail in this work.
