The grammar of Panini is one of the most remarkable literary works that the world has ever seen, and no other country can produce any grammatical sys… - Panini

The author of the oldest extant Sanskrit grammar was Panini, a native of extreme north-west India, ... His work consists of nearly 4000 aphorisms, each of which owing to the extreme conciseness of the style, generally consists of not more than two or three words. Hence, the whole grammar could be printed within the compass of about thirty-five octavo pages. Yet it describes the entire Sanskrit language with a completeness which has never been equalled elsewhere. Thus it is at once the shortest and the fullest grammar in the world.

While Pāṇini's work is purely grammatical and lexicographic, cultural and geographical inferences can be drawn from the vocabulary he uses in examples, and from his references to fellow grammarians, which show he was a northwestern person. New deities referred to in his work include Vasudeva (4.3.98). The concept of dharma is attested in his example sentence dharmam carati "he observes the law" (cf. Taittiriya Upanishad 1.11).

The most successful, hence most prominent amongst these grammarians was Panini. His grammar, surpassing all others in tightness and precision, became the standard and remained so undisputedly until today. Panini was able to joint the original devanagari language into an exact framework of rules, thus preserving it for the posterity. Since his time, this language is called Sanskrit, “joined together, refined”.
