Aṣṭādhyāyī

Indian postage stamp commemorating Pāṇini.

Aṣṭādhyāyī. A Sanskrit treatise on grammar written in the 6th to 5th century BCE by the Indian grammarian Pāṇini. This work set the linguistic standards for Classical Sanskrit. It sums up the science of phonetics and grammar that had evolved in the Vedic religion.

The editors of learnsanskrit.org state:

The core of the Pāṇinian system is the Aṣṭādhyāyī (“the eight chapters”), a system of around 4000 rules divided into eight major chapters. Together, these rules generate grammatically valid Sanskrit expressions. And if an expression is not grammatically valid, then it cannot be generated by the system of rules.

In other words, we can say that the Aṣṭādhyāyī defines a generative grammar for Sanskrit. And it does so by defining a formal language to specify the various transformations of sounds, words, and sentences that Sanskrit requires. So in some sense, the Aṣṭādhyāyī is the first program.

The Aṣṭādhyāyī is so comprehensive that essentially all later Sanskrit literature is consistent with its model of Sanskrit. Perhaps Pāṇini's greatest achievement is that he “froze” Sanskrit and preserved the form it has today.
