New Books Network Rishi Rajpopat, "Panini's Perfect Rule: A Modern Solution to an Ancient Problem in Sanskrit Grammar" (Harvard UP, 2025)
Apr 9, 2026
Rishi Rajpopat, Research Assistant Professor and author of Panini’s Perfect Rule, studies Pāṇini’s Ashtadhyayi and Sanskrit grammar. He explains the decades-long puzzle of conflicting rules. He proposes a reinterpretation that reads “later” as right-hand in the word. He walks through concrete derivations and contrasts Pāṇini’s rule-based system with modern machine-learning approaches.

Episode notes
Panini's Grammar Is A Generative Machine
- Panini designed the Ashtadhyayi as a generative linguistic machine that derives words then composes sentences using mechanistic rules.
- He built ~4,000 concise rules so each derivation step applies one rule to produce grammatically correct Sanskrit words automatically.
Rule Conflict Broke The Machine Ideal
- A pervasive problem in Panini studies is simultaneous applicability of multiple rules during a derivation, which breaks the 'machine' ideal if humans must choose.
- Early commentators misread Panini's single meta-rule about conflicts, triggering centuries of added meta-rules and complexity.
Question Foundational Interpretations Before Adding Rules
- When a long scholarly tradition rests on an early interpreter's assumption, question that assumption rather than building more exceptions.
- Rajpopat advises re-examining primary texts for simpler elegant readings before appending meta-rules.
