He was a renowned Indian grammarian and linguist who lived in ancient India, most likely between the 6th and 4th centuries BCE. His masterpiece, the Aṣṭādhyāyī, is a comprehensive and highly structured treatise on Sanskrit grammar that has had a profound influence on the study of language and linguistics.
While other scholars had contributed to the development of Sanskrit grammar before Pāṇini, his work is considered the most authoritative and influential. It is structured in eight chapters and includes over 4,000 sūtras (rules) that cover all aspects of Sanskrit grammar, including morphology, syntax, and phonology.
His work has been studied and analyzed for centuries, and it continues to be a valuable resource for linguists and scholars today.
