A report on Pāṇini

Pāṇini and Yāska are the two celebrated ancient scholars of Vyākaraṇa; both are dated to several centuries prior to the start of the common era, with Pāṇini likely from the fifth century BCE.

The author of the Mahābhāṣya, an ancient treatise on Sanskrit grammar and linguistics, based on the Aṣṭādhyāyī of Pāṇini. This Patañjali's life is dated to mid 2nd century BCE by both Western and Indian scholars. This text was titled as a bhashya or "commentary" on Kātyāyana-Pāṇini's work by Patanjali, but is so revered in the Indian traditions that it is widely known simply as Mahā-bhasya or "Great commentary". As per Ganesh Sripad Huparikar, actually, Patanjali (2nd century BCE), the forerunner among ancient grammatical commentators, “adopted an etymological and dialectical method of explaining in the whole of his 'Mahābhāshya' (Great Commentary), and this has assumed, in the later commentary literature the definite form of 'Khanda-anvaya'.” So vigorous, well reasoned and vast is his text, that this Patanjali has been the authority as the last grammarian of classical Sanskrit for more than 2,000 years, with Pāṇini and Kātyāyana preceding him. Their ideas on structure, grammar and philosophy of language have also influenced scholars of other Indian religions such as Buddhism and Jainism.

The history of morphological analysis dates back to the ancient Indian linguist Pāṇini, who formulated the 3,959 rules of Sanskrit morphology in the text Aṣṭādhyāyī by using a constituency grammar.

Sanskrit can also more narrowly refer to Classical Sanskrit, a refined and standardized grammatical form that emerged in the mid-1st millennium BCE and was codified in the most comprehensive of ancient grammars, the Aṣṭādhyāyī ('Eight chapters') of Pāṇini.

The Aṣṭādhyāyī of Pāṇini, from c. 4th century BC in Ancient India, is often cited as an example of a premodern work that approaches the sophistication of a modern syntactic theory since works on grammar had been written long before modern syntax came about.

The first systematic grammar, of Sanskrit, originated in Iron Age India, with Yaska (6th century BC), Pāṇini (6th–5th century BC ) and his commentators Pingala (c.

Authored by Sanskrit philologist and scholar Pāṇini and dated to around 500 BCE, it describes the language as current in his time, specifically the dialect and register of an élite of model speakers, referred to by Pāṇini himself as śiṣṭa.

It was studied and codified by Sanskrit grammarians from the later Vedic period (roughly 8th century BCE), culminating in the Pāṇinian grammar of the 4th century BCE.

The earliest activities in the description of language have been attributed to the 6th-century-BC Indian grammarian Pāṇini who wrote a formal description of the Sanskrit language in his .

There is no use of ' as a technical term prior to Patañjali, but Pāṇini (6.1.123) refers to a grammarian named ' as one of his predecessors.
