New Books in Critical Theory 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/Associate Professor and scholar of Sanskrit grammar, presents his reinterpretation of Pāṇini’s Ashtadhyayi. He explains the ‘linguistic machine’ nature of the grammar and the longstanding problem of competing rules. He argues that ‘later’ means rightmost operation in the text and shows how this resolves conflicts with concrete Sanskrit examples.

Episode notes
Panini's Grammar Is A Generative Machine
- Panini's Ashtadhyayi is not a descriptive grammar but a generative linguistic machine that derives words and sentences via ordered rule application.
- It builds words from bases and suffixes so every step should apply a single rule producing automatic correct outputs without human choice.
Rule Conflict Was Misread For Centuries
- A core problem in Panini scholarship is simultaneous rule applicability requiring a meta-rule to decide which rule wins.
- Traditionally commentators read Panini's meta-rule to mean the later rule in the serial order defeats earlier ones, spawning many corrective meta-rules.
Later Means Rightmost Wins
- Rajpopat reinterprets Panini's 'apply the later rule' to mean the rule applying to the right-most (later in pronunciation/writing) part wins.
- This left-to-right, rightmost-wins reading resolves many longstanding contradictions and wrong derivations.
