Sanskrit's grammatical tradition centers on Panini's Ashtadhyayi ('Eight Chapters'), composed around the 4th century BCE — one of the most sophisticated grammatical systems ever devised for any language, with nearly 4,000 sutras (rules) systematically describing Sanskrit's phonology, morphology, and syntax with extraordinary precision and economy.

Panini's grammar is so rigorously systematic that it has been compared to a generative formal system, predating modern linguistic formalism by over two millennia.

• ›The Ashtadhyayi remains the foundational reference for Classical Sanskrit grammar studied even today
• ›Two later commentators, Katyayana (vartikas) and Patanjali (Mahabhashya), expanded and clarified Panini's rules
• ›Understanding Sanskrit grammar at an advanced level means engaging with this exact tradition, not a simplified modern paraphrase
