Ashtadhyayi is an ancient Sanskrit text composed by the grammarian Pāṇini around the 4th century BCE. It serves as a foundational work in the field of Sanskrit grammar, outlining the rules and structures of the language. The text consists of eight chapters, or "adhyāyas," which systematically describe the formation of words and sentences. The Ashtadhyayi employs a concise and technical style, using a unique system of rules and meta-rules. Its influence extends beyond linguistics, impacting fields such as linguistics, philosophy, and computer science. Scholars continue to study this work for its insights into language structure and its historical significance in the development of grammar.
