There is in the rules or definitions (sutras) of Panini a remarkably subtle and penetrating account of Sanskrit grammar. The construction of sentences, compound nouns, and the like is explained through ordered rules operating on underlying structures in a manner strikingly similar in part to modes of modern theory. As might be imagined, this perceptive Indian grammatical work held great fascination for 20th-century theoretical linguists. A study of Indian logic in relation to Paninian grammar alongside AristotleAristotelian]] and Western logic in relation to Greek grammar and its successors could bring illuminating insights.

The descriptive Grammar of Sanskrit, which Panini, brought to its high- est perfection, is one of the greatest monuments of human intelligence and (what concerns us more) an indispensable model for description of languages. The only achievement in our field, which can take rank with it is the historical linguistics of the nineteenth century and this indeed owed its origin largely to Europe’s acquaintance with the Indian Grammar. One forgot that the Comparative Grammar of the Indo- European languages got its start only when the Paninian analysis of an Indo-European language became known in Europe. . . . If the accen- tuation of Sanskrit and Greek, for instance had been unknown, Verner could not have discovered the Pre-Germanic sound change, that goes by his name. Indo-European Comparative Grammar had (and has) at its service, only one complete description of a language, the grammar of Panini. For all other Indo-European languages it had only the traditional grammars of Greek and Latin woefully incomplete and unsystematic. (1933: 267–76)

Panini was a Sanskrit grammarian who gave a comprehensive and scientific theory of phonetics, phonology, and morphology. Sanskrit was the classical literary language of the Indian Hindus and Panini is considered the founder of the language and literature. It is interesting to note that the word "Sanskrit" means "complete" or "perfect" and it was thought of as the divine language, or language of the gods.

The grammar of Panini stands supreme among the grammars of the world, alike for its precision of statement, and for its thorough analysis of the roots of the language and of the formative principles of words. By employing an algebraic terminology it attains a sharp succinctness unrivalled in brevity, but at times enigmatical. It arranges, in logical harmony, the whole phenomena, which the Sanskrit language presents, and stands forth as one of the most splendid achievements of human invention and industry. So elaborate is the structure that doubts have arisen whether its complex rules offormation and phonetic change, its polysyllabic derivatives, its ten conjugations with1heir multiform aorists and long array of tenses, could ever have been the spoken language of a people." 29

Panini’s grammar is the earliest scientific grammar in the world, the earliest extant grammar of any language, and one of the greatest ever written. It was the discovery of Sanskrit by the West, at the end of the 18th century, and the study of Indian methods of analyzing language that revolutionized our study of language and grammar, and gave rise to our science of comparative philology … The study of language in India was much more objective and scientific than in Greece or Rome. The interest was in empirical investigation of language, rather than philosophical and syntactical. Indian study of language was as objective as the dissection of a body by an anatomist.

A treatise called Astadhyayi (or Astaka) is Panini's major work. It consists of eight chapters, each subdivided into quarter chapters. In this work Panini distinguishes between the language of sacred texts and the usual language of communication. Panini gives formal production rules and definitions to describe Sanskrit grammar. Starting with about 1700 basic elements like nouns, verbs, vowels, consonants he put them into classes. The construction of sentences, compound nouns etc., is explained as ordered rules operating on underlying structures in a manner similar to modern theory. In many ways Panini's constructions are similar to the way that a mathematical function is defined today.

Sanskrit is constructed like geometry and follows a rigorous logic. It is theoretically possible to explain the meaning of the words according to the combined sense of the relative letters, syllables and roots. Sanskrit has no meanings by connotations and consequently does not age. Panini's language is in no way different from that of Hindu scholars conferring in Sanskrit today.

Our Gods spoke in Sanskrit; our sages thought in Sanskrit, our poets wrote in Sanskrit. All that is best in us—the best thoughts, the best ideas, the best lines—seeks instinctively to clothe itself in Sanskrit. To millions it is still the language of their Gods; to others it is the language of their ancestors; to all it is the language par excellence; a common inheritance, a common treasure that enriches all the family of our sister languages. 46

The creation of Sanskrit, the “refined” language, was a prodigious work on a grand scale. Grammarians and semanticists of genius undertook to create a perfect language, artificial and permanent, belonging to no one, that was to become the language of the entire culture. Sanskrit is built on a basis of Vedic and the Prakrits, but has a much more complex grammar, established according to a rigorous logic. It has an immense vocabulary and a very adaptable grammar, so that words can be grouped together to express any nuance of an idea, and verb forms can be found to cover any possibility of tense, such as future intentional in the past, present continuing into the future, and so on. Furthermore, Sanskrit possesses a wealth of abstract nouns, technical and philosophical terms unknown in any other language. Modern Indian scholars of Sanskrit culture have often remarked that many of the new concepts of nuclear physics or modern psychology are easy for them to grasp, since they correspond exactly to familiar notions of Sanskrit terminology.

Classical Sanskrit is often called Paninian Sanskrit. Western scholars are of the opinion that this is a continuation of Old Indo-Aryan in the MIA period. This is only partially true.

Burrow, whose The Sanskrit Language (1973) is still the authority in this field, says: "Vedic is a language which in most respects is more archaic and less altered from original Indo-European than any other member of the family" (34); he also states that root nouns, "very much in decline in the earliest recorded Indo-European languages", are preserved better in Sanskrit, and later adds, "Chiefly owing to its antiquity the Sanskrit language is more readily analysable, and its roots more easily separable from accretionary elements than… any other IE language" (123, 289).
