In the fifteenth century Rāmachandra, in his Prakriyā-kaumudī, or "Moonlight of Method," endeavoured to make Pāṇini's grammar easier by a more practical arrangement of its matter. Bhaṭṭoji's Siddhānta-kaumudī (seventeenth century) has a similar aim; an abridgment of this work, the Laghu-kaumudī, by Varadarāja is commonly used as an introduction to the native system of grammar. Among non-Pāṇinean grammarians may be mentioned Chandra (about 600 A.D.), the pseudo-Çākaṭāyana (later than the Kāçikā), and, the most important, Hemachandra (12th century), author of a Prākrit grammar.

The current language Pāṇini describes is very close in structure to the late Vedic found in certain Brāhmaṇa texts. As noted earlier, scholars have recognized other varieties of Sanskrit. Epic Sanskrit is so called because it is represented principally in the two epics, Mahābhārata (“Great Epic of the Bhārata Dynasty”) and Rāmāyaṇa (“Romance of Rāma”). In the latter the term saṃskṛta ‘adorned, cultivated, purified (by grammar)’ is encountered, possibly for the first time with reference to the language. The date of composition for the core of early Epic Sanskrit is considered to be in the centuries just preceding the Common Era.

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.
