The name Pāṇini is a patronymic meaning descendant of Paṇina.{{cite book |author1=Pāṇini |url=https://books.google.com/books?id=iSDakY97XckC&pg=PR20 |title=Aṣṭādhyāyī of Pāṇini |author2=Sumitra Mangesh Katre |publisher=Motilal Banarsidass |year=1989 |isbn=978-81-208-0521-7 |page=xx}} His full name was Dakṣiputra Pāṇini according to verses 1.75.13 and 3.251.12 of Patanjali's Mahābhāṣya, with the first part suggesting his mother's name was Dakṣi.{{sfn|Scharfe|1977|p=88}}

Nothing definite is known about when Pāṇini lived, not even in which century he lived. Pāṇini has been dated between the seventh{{sfn|Bod|2013|p=14}} or sixth{{sfn|Scharfe|1977|p=88}} and fourth century BCE.{{sfn|Vergiani|2017|p=243, n.4}}{{sfn|Bronkhorst|2016|p=171}}{{sfn|Houben|2009|p=6}}{{sfn|Cardona|1997|p=268}}{{sfn|Bronkhorst|2019}}{{refn|group=note|name="dating"}}

George Cardona (1997) in his authoritative survey and review of Pāṇini-related studies, states that the available evidence strongly supports a dating not before 400 BCE, while earlier dating depends on interpretations and is not probative.{{sfn|Cardona|1997|pp=261–268}}

Based on numismatic findings, von Hinüber (1989) and Falk (1993) place Pāṇini in the mid-4th century BCE.{{sfn|Vergiani|2017|p=243, n.4}}{{sfn|Bronkhorst|2016|p=171}}{{sfn|Houben|2009|p=6}}{{sfn|Bronkhorst|2019}} Pāṇini's rupya (A 5.2.119, A 5.2.120, A. 5.4.43, A 4.3.153,) mentions a specific gold coin, the niṣka, in several sutras, which originated in India in the 4th-century BCE.{{sfn|Houben|2009|p=6}} According to Houben, "the date of "{{c.|350 BCE}} for Pāṇini is thus based on concrete evidence which till now has not been refuted."{{sfn|Houben|2009|p=6}} According to Bronkhorst, there is no reason to doubt the validity of Von Hinüber's and Falk's argument, setting the terminus post quem{{refn|group=note|The earliest time or historical period during which an event may have happened}} for the date of Pāṇini at 350 BCE or the decades thereafter.{{sfn|Bronkhorst|2019}} According to Bronkhorst,

{{blockquote|...thanks to the work carried out by Hinüber (1990:34-35) and Falk (1993: 303-304), we now know that Pāṇini lived, in all probability, far closer in time to the period of Aśoka than had hitherto been thought. According to Falk's reasoning, Panini must have lived during the decade following 350 BCE, that is, just before (or contemporaneously with?) the invasion by Alexander of Macedonia.{{sfn|Bronkhorst|2016|p=171}}}}

It is not certain whether Pāṇini used writing for the composition of his work, though it is generally agreed that he knew of a form of writing, based on references to words such as lipi ("script") and lipikara ("scribe") in section 3.2 of the Aṣṭādhyāyī.{{cite book |author=Richard Salomon |author-link=Richard G.

Harry Falk in his 1993 overview states that ancient Indians neither knew nor used writing scripts, and Pāṇini's mention is likely a reference to Semitic and Greek scripts.{{cite book|last1=Falk|first1=Harry |author-link=Harry Falk (Indologist)|title=Schrift im alten Indien: ein Forschungsbericht mit Anmerkungen |trans-title= Writing in ancient India: a research report with notes |date=1993|publisher=Gunter Narr Verlag|language=de|pages=109–167|isbn=9783823342717}} In his 1995 review, Salomon questions Falk's arguments and writes it is "speculative at best and hardly constitutes firm grounds for a late date for Kharoṣṭhī. The stronger argument for this position is that we have no specimen of the script before the time of Aśoka, nor any direct evidence of intermediate stages in its development; but of course this does not mean that such earlier forms did not exist, only that, if they did exist, they have not survived, presumably because they were not employed for monumental purposes before Aśoka".{{cite journal | last=Salomon | first=Richard |author-link= Richard G.

Scharfe adds that the best evidence, at the time of his review, is that no script was used in India, aside from the Northwest Indian subcontinent, before around 300 BCE because Indian tradition "at every occasion stresses the orality of the cultural and literary heritage."{{citation|last= Scharfe|first= Hartmut|series= Handbook of Oriental Studies|title= Education in Ancient India|pages= 10–12|year=2018|publisher=Brill |location=Leiden, Netherlands |isbn=9789047401476}} Kenneth Norman states that writing scripts in ancient India evolved over long periods of time like other cultures, that it is unlikely that ancient Indians developed a single complete writing system at one and the same time in the Mauryan era. It is even less likely, states Norman, that a writing script was invented during Ashoka's rule, starting from nothing, for the specific purpose of writing his inscriptions and then it was understood all over South Asia where the Aśoka pillars are found.{{cite book|author=Oskar von Hinüber|author-link=Oskar von Hinüber|title=Der Beginn der Schrift und frühe Schriftlichkeit in Indien|trans-title=The beginning of writing and early writing in India|year=1989|publisher=Akademie der Wissenschaften und der Literatur|oclc= 22195130|pages=241–245|isbn=9783515056274|language=de}} Jack Goody states that ancient India likely had a "very old culture of writing" along with its oral tradition of composing and transmitting knowledge, because the corpus of Vedic literature is too vast, consistent and complex to have been entirely created, memorized, accurately preserved and spread without a written system.{{cite book|author=Jack Goody|author-link=Jack Goody|title=The Interface Between the Written and the Oral|url=https://archive.org/details/interfacebetween00good|url-access=registration|year=1987|publisher=Cambridge University Press|isbn=978-0-521-33794-6|pages=[https://archive.org/details/interfacebetween00good/page/110 110]–124}} Falk disagrees with Goody, and suggests that it is a Western presumption and inability to imagine that remarkably early scientific achievements such as Pāṇini's grammar (5th to 4th century BCE), and the creation, preservation and wide distribution of the large corpus of the Brahmanic Vedic literature and the Buddhist canonical literature were possible without any writing scripts. Johannes Bronkhorst disagrees with Falk, and states, "Falk goes too far. It is fair to expect that we believe that Vedic memorisation — though without parallel in any other human society — has been able to preserve very long texts for many centuries without losing a syllable. (...) However, the oral composition of a work as complex as Pāṇini's grammar is not only without parallel in other human cultures, it is without parallel in India itself. (...) It just will not do to state that our difficulty in conceiving any such thing is our problem".{{cite journal | last=Bronkhorst | first=Johannes | author-link=Johannes Bronkhorst | title=Literacy and Rationality in Ancient India | journal= Asiatische Studien/Études Asiatiques (Asian Studies) | volume=56 | issue=4 | year=2002 | pages=797–831 | url=https://core.ac.uk/download/pdf/77159988.pdf}}}}

Pāṇini cites at least ten grammarians and linguists before him: Āpiśali, Kāśyapa, Gārgya, Gālava, Cākravarmaṇa, Bhāradvāja, Śākaṭāyana, Śākalya, Senaka, Sphoṭāyana and Yaska.{{sfn|Cardona|1997|p=§1.3}} According to Kamal K.

The Sanskrit epic Brihatkatha and the Buddhist scripture Mañjuśrī-mūla-kalpa both mention Pāṇini to have been a contemporary with the king Dhana Nanda (reigned 329-321 BCE), the last monarch of the Nanda Empire before Chandragupta Maurya came to power.{{Cite book |last=Singh |first=Upinder |author-link=Upinder Singh |url=https://books.google.com/books?id=H3lUIIYxWkEC |title=A History of Ancient and Early Medieval India: From the Stone Age to the 12th Century |date=2008 |publisher=Pearson Longman |isbn=978-81-317-1120-0 |pages=258 |language=en}}

Cardona offers an earlier date for Pāṇini,{{sfn|Cardona|1997|p=261-262}} by arguing the compound word Yona, discussed in sutra 4.1.49, instead of referring to a writing (lipi) c.q. cuneiform of the Achaemenid Empire, or the Greek of Alexander the Great, refers to Greek women; and that Indus valley residents possibly had contacts with Greek women before Darius's 535 BCE, or Alexander's 326 BCE conquests.{{sfn|Cardona|1997|p=261}}{{refn|group=note|In 1862 Max Müller argued that yavana may have meant "Greek"{{refn|group=note|Ionian}} during Pāṇinis time, but may also refer to Semitic or dark-skinned Indian people.{{cite book|author=Max Müller |author-link=Max Müller |title=On Ancient Hindu Astronomy and Chronology|url=https://books.google.com/books?id=VB1bAAAAcAAJ&pg=PA70 |year=1862|pages=footnotes of 69–71|bibcode=1862ahac.book.....M}}{{cite book|author=Patrick Olivelle |author-link=Patrick Olivelle |title=Dharmasutras|url=https://books.google.com/books?id=gnVxqvPg9a0C |year=1999|publisher=Oxford University Press|isbn=978-0-19-283882-7|page=xxxii with footnote 13}}}} K. B. Pathak (1930) argues that the kumāraśramaṇa, of sutra 2.1.70, derived from śramaṇa, which refers to female renunciates, c.q. "Buddhist nuns", could also refer to Jain Aryika, of unknown origin, possibly permitting Pāṇini to be placed before the, 5th century BCE, Gautama Buddha.{{sfn|Cardona|1997|p=261-262}} Others, based on Panini's linguistic style, date his works to the sixth or fifth century BCE, as:

• According to Bod, Pāṇini's grammar defines Classical Sanskrit, so Pāṇini is chronologically placed in the later part of the Vedic period, corresponding to the seventh to fifth century BCE.{{sfn|Bod|2013|p=14-18}}
• According to A. B. Keith, the Sanskrit text that most matches the language described by Pāṇini is the Aitareya Brāhmaṇa ({{c.|8th – 6th BCE}}).{{Cite book |last=Keith |first=Arthur Berriedale |author-link=Arthur Berriedale Keith |title=Rigveda Brahmanas: the Aitareya and Kauṣītaki Brāhmaṇas of the Rigveda |date=1998 |publisher=Motilal Banarsidass |isbn=978-8120813595 |location=Delhi |language=en |oclc=611413511}}

Nothing certain is known about Pāṇini's personal life. In an inscription of Siladitya VII of Valabhi,{{Who|date=October 2023}} he is called Śalāturiya, which means "a man from Salatura".{{Citation needed|date=October 2023}} This means Pāṇini lived in Salatura in ancient Gandhara (present day north-west Pakistan), which likely was near Lahor, a town at the junction of the Indus and Kabul rivers.{{refn|group=note|now a part of the Swabi District of modern Pakistan}}{{cite book |author=Hartmut Scharfe |url=https://books.google.com/books?id=2_VbnWkZ-SYC&pg=PA88 |title=Grammatical Literature |publisher=Otto Harrassowitz |year=1977 |isbn=978-3-447-01706-0 |pages=88 with footnotes}}{{Cite book |last=Saroja Bhate |url=http://archive.org/details/in.ernet.dli.2015.204734 |title=Panini |publisher=Sahitya Akademi |year=2002 |isbn=81-260-1198-X |pages=4}} According to the memoirs of the 7th-century Chinese scholar Xuanzang, there was a town called Suoluoduluo on the Indus where Pāṇini was born, and where he composed the Qingming-lun (Sanskrit: Vyākaraṇa).{{Citation |title=Encyclopaedia of Hinduism |pages=1983–2007 |year=1997 |editor-last=Singh |editor-first=Nagendra Kr. |url=https://books.google.com/books?id=Vl8_VgikeLcC&q=statue&pg=PA1988 |location=New Delhi |publisher=Centre for International Religious Studies: Anmol Publications |isbn=978-81-7488-168-7}}{{cite book |last=Mishra |first=Giridhar |author-link=Rambhadracharya |title=अध्यात्मरामायणेऽपाणिनीयप्रयोगाणां विमर्शः |publisher=Sampurnanand Sanskrit University |year=1981 |place=Varanasi, India |language=sa |trans-title=Deliberation on non-Paninian usages in the Adhyatma Ramayana |chapter=प्रस्तावना |trans-chapter=Introduction |access-date=21 May 2013 |chapter-url=http://jagadgururambhadracharya.org/works/arapv/prastavana.php |archive-url=https://web.archive.org/web/20140311211052/https://jagadgururambhadracharya.org/works/arapv/prastavana.php |archive-date=11 March 2014}}

According to Hartmut Scharfe, Pāṇini lived in Gandhara, close to the borders of the Achaemenid Empire, and Gandāra was then an Achaemenian satrapy following the Achaemenid conquest of the Indus Valley. He must, therefore, have been technically a Persian subject but his work shows no awareness of the Persian language.{{sfn|Scharfe|1977|p=88}}{{cite journal |last1=Lal |first1=Shyam Bihari |author-link=Shyam Bihari Lal |date=2004 |title=Yavanas in Ancient Indian Inscriptions |journal=Proceedings of the Indian History Congress |volume=65 |pages=1115–1120 |issn=2249-1937 |jstor=44144820}} According to Patrick Olivelle, Pāṇini's text and references to him elsewhere suggest that "he was clearly a northerner, probably from the northwestern region".{{cite book |author=Patrick Olivelle |author-link=Patrick Olivelle |url=https://books.google.com/books?id=gnVxqvPg9a0C |title=Dharmasutras |publisher=Oxford University Press |year=1999 |isbn=978-0-19-283882-7 |pages=xxvi–xxvii}}

According to Kathāsaritsāgara legends Pāṇini studied under his guru Varsha in Pataliputra. Not the brightest of his disciples, on the advice of Varsha's wife, Pāṇini went to the Himalayas to do penance and gain knowledge from Shiva. Sutras were granted by Shiva, who danced and played his damaru before Pāṇini and produced the basic sounds of these sutras, Panini accepted them and they are now known as the Shiva Sutras. Armed with this new grammar Pāṇini came back from the Himalayas to Pataliputra. But at the same time, Vararuchi, another disciple of Varsha had learned of a grammar from Indra. They engaged in a debate which lasted eight days and on the last day, with Vararuchi emerging dominant, Pāṇini was able to defeat him with the help of Shiva who destroyed Vararuchi's grammar book. Pāṇini then defeated the rest of Varsha's disciples and emerged as the greatest grammarian.Vettam Mani. [https://archive.org/stream/puranicencyclopa00maniuoft Puranic Encyclopedia: a comprehensive dictionary with special reference to the epic and Puranic literature]. Motilal Banarsidass. 1975.

Pāṇini is believed to have spent the major portion of his life in Pataliputra and according to some pandits, he was born and brought up there, the ancestors of Pāṇini having already moved there from Salatura. Pāṇini, has also been associated with the University of Taxila.{{cite book|last1=Prakash|first1=Buddha|title=Political And Social Movements in Ancient Punjab|date=1964 |publisher=Motilal Banarsidass|isbn=9788120824584|url=https://books.google.com/books?id=U6QSPwAACAAJ|quote=Pāṇini and Kautilya, two masterminds of ancient times, were also brought up in the academic traditions of Taxila.}}

Growing out of a centuries-long effort to preserve the language of the Vedic hymns from "corruption", the Aṣtādhyāyī is the high point of a vigorous, sophisticated grammatical tradition devised to arrest language change. The Aṣtādhyāyī's preeminence is underlined by the fact that it eclipsed all similar works that came before: while not the first, it is the oldest such text surviving in its entirety.{{Cite book |last=Burrow |first=Thomas |author-link=Thomas Burrow |title=The Sanskrit language |date=2001 |publisher=Motilal Banarsidass |isbn=978-81-208-1767-8 |edition=1st Indian |location=Delhi |pages=49}}{{Cite book |last=Itkonen |first=Eas |author-link=Esa Itkonen |title=Universal History of Linguistics: India, China, Arabia, Europe |publisher=John Benjamins Publishing Company |year=1991 |isbn=9789027277671 |pages=69}}{{Cite book |last=Burnell |first=Arthur Coke |author-link=Arthur Coke Burnell |url=https://books.google.com/books?id=1DYLAAAAQAAJ&dq=whitney+panini+grammar&pg=PA85 |title=On the Aindra School of Sanskrit Grammarians, Their Place in the Sanskrit and Subordinate Literatures |date=1875 |publisher= |pages=87 |language=en}}{{Cite book |last1=Embleton |first1=Sheila |author-link=Sheila Embleton |url=https://books.google.com/books?id=iT5IAAAAQBAJ&dq=whitney+panini+grammar&pg=PA154 |title=The Emergence of the Modern Language Sciences: Studies on the transition from historical-comparative to structural linguistics in honour of E.F.K.

The Aṣṭādhyāyī consists of 3,959 sūtras{{efn-ua|aphoristic threads}} in eight chapters, which are each subdivided into four sections or pādas. The text takes material from lexical lists (dhātupāṭha, gaṇapātha) as input and describes the algorithms to be applied to them for the generation of well-formed words. Such is its intricacy that the correct application of its rules and metarules is still being worked out centuries later.{{Cite web|url=https://www.bbc.com/news/articles/cg3gw9v7jnvo|title=Cambridge PhD student solves 2,500-year-old Sanskrit problem|website=BBC News|date=15 December 2022 }}{{Cite web|url=https://www.cam.ac.uk/stories/solving-grammars-greatest-puzzle|title=Solving grammar's greatest puzzle|website=University of Cambridge|date=15 December 2022 }}

The Aṣṭādhyāyī, composed in an era when oral composition and transmission was the norm, is staunchly embedded in that oral tradition. In order to ensure wide dissemination, Pāṇini is said to have preferred brevity over clarityWhitney, p. xiii—it can be recited end-to-end in two hours. This has led to the emergence of a great number of commentaries{{efn-ua|bhāṣyas}} of his work over the centuries, which for the most part adhere to the foundations laid by Pāṇini's work.Burrow, §2.1.Coulson, p xvi.

Indian curriculums in the late classical era had at their core a system of grammatical study and linguistic analysis.{{Cite book |last=Filliozat |first=Pierre-Sylvain |title=The Sanskrit language: an overview: history and structure, linguistic and philosophical representations, uses and users |date=2000 |publisher=Indica Books |isbn=978-81-86569-17-7 |location=Varanasi}} The core text for this study was the Aṣṭādhyāyī of Pāṇini, the sine qua non of learning.Fallon, Oliver. 2009. Bhatti's Poem: The Death of Rávana ({{IAST|Bhaṭṭikāvya}}). New York: Clay Sanskrit Library. {{ISBN|978-0-8147-2778-2}} This grammar of Pāṇini had been the object of intense study for the ten centuries prior to the composition of the Bhaṭṭikāvya. It was Bhaṭṭi's purpose to provide a study aid to Pāṇini's text by using the examples already provided in the existing grammatical commentaries in the context of the Rāmāyaṇa. The intention of the author was to teach this advanced science through a relatively easy and pleasant medium. In his own words:

This composition is like a lamp to those who perceive the meaning of words and like a hand mirror for a blind man to those without grammar.

This poem, which is to be understood by means of a commentary, is a joy to those sufficiently learned: through my fondness for the scholar I have here slighted the dullard.

Bhaṭṭikāvya 22.33–34.

Pāṇini is known for his text Aṣṭādhyāyī, a sutra-style treatise on Sanskrit grammar,{{sfn|Staal|1965}}{{sfn|Lochtefeld|2002|p=64–65, 140, 402}} which consists of 3,996{{Cite book |last=Singh |first=Upinder |title=A History of Ancient and Early Medieval India |publisher=Pearson |year=2021 |isbn=978-81-317-1677-9 |pages=258}} verses or rules on linguistics, syntax and semantics in "eight chapters" which is the foundational text of the Vyākaraṇa branch of the Vedanga, the auxiliary scholarly disciplines of the Vedic period.W.

Pāṇini's analysis of noun compounds still forms the basis of modern linguistic theories of compounding in Indian languages. Pāṇini's comprehensive and scientific theory of grammar is conventionally taken to mark the start of Classical Sanskrit.{{cite book |author1=Yuji Kawaguchi |url=https://books.google.com/books?id=iaZxAAAAQBAJ&pg=PA223 |title=Corpus-based Analysis and Diachronic Linguistics |author2=Makoto Minegishi |author3=Wolfgang Viereck |publisher=John Benjamins Publishing Company |year=2011 |isbn=978-90-272-7215-7 |pages=223–224}} His systematic treatise inspired and made Sanskrit the preeminent Indian language of learning and literature for two millennia.

Pāṇini's theory of morphological analysis was more advanced than any equivalent Western theory before the 20th century.{{cite book |last1=Staal |first1=Frits |url=https://books.google.com/books?id=7IqsyNmt8XYC&q=Panini |title=Universals: studies in Indian logic and linguistics |publisher=University of Chicago Press |year=1988 |isbn=9780226769998 |page=47}} His treatise is generative and descriptive, uses metalanguage and meta-rules, and has been compared to the Turing machine wherein the logical structure of any computing device has been reduced to its essentials using an idealized mathematical model.{{cite journal |last1=Kak |first1=Subhash C. |date=January 1987 |title=The Paninian approach to natural language processing |journal=International Journal of Approximate Reasoning |volume=1 |issue=1 |pages=117–130 |doi=10.1016/0888-613X(87)90007-7 |doi-access=free}}

Pāṇini's work became known in 19th-century Europe, where it influenced modern linguistics initially through Franz Bopp. Subsequently, a wider body of work influenced Sanskrit scholars such as Ferdinand de Saussure, Leonard Bloomfield, and Roman Jakobson. Frits Staal (1930–2012) discussed the impact of Indian ideas on language in Europe. After outlining the various aspects of the contact, Staal notes that the idea of formal rules in language – proposed by Ferdinand de Saussure in 1894 and developed by Noam Chomsky in 1957 – has origins in the European exposure to the formal rules of Pāṇinian grammar. In particular, de Saussure, who lectured on Sanskrit for three decades, may have been influenced by Pāṇini and Bhartrihari; his idea of the unity of the signifier-signified in the sign somewhat resembles the notion of Sphoṭa. More importantly, the very idea that formal rules can be applied to areas outside of logic or mathematics may itself have been catalysed by Europe's contact with the work of Sanskrit grammarians.Frits Staal, The science of language, Chapter 16, in Gavin D. Flood, ed. The Blackwell Companion to Hinduism Blackwell Publishing, 2003, 599 pages {{ISBN|0-631-21535-2}}, {{ISBN|978-0-631-21535-6}}. p. 357-358

Pāṇini, and the later Indian linguist Bhartrihari, had a significant influence on many of the foundational ideas proposed by Ferdinand de Saussure, professor of Sanskrit, who is widely considered the father of modern structural linguistics and with Charles S. Peirce on the other side, to semiotics, although the concept Saussure used was semiology. Saussure himself cited Indian grammar as an influence on some of his ideas. In his Mémoire sur le système primitif des voyelles dans les langues indo-européennes (Memoir on the Original System of Vowels in the Indo-European Languages) published in 1879, he mentions Indian grammar as an influence on his idea that "reduplicated aorists represent imperfects of a verbal class." In his De l'emploi du génitif absolu en sanscrit (On the Use of the Genitive Absolute in Sanskrit) published in 1881, he specifically mentions Pāṇini as an influence on the work.

Prem Singh, in his foreword to the reprint edition of the German translation of Pāṇini's Grammar in 1998, concluded that the "effect Panini's work had on Indo-European linguistics shows itself in various studies" and that a "number of seminal works come to mind," including Saussure's works and the analysis that "gave rise to the laryngeal theory," further stating: "This type of structural analysis suggests influence from Panini's analytical teaching." George Cardona, however, warns against overestimating the influence of Pāṇini on modern linguistics: "Although Saussure also refers to predecessors who had taken this Paninian rule into account, it is reasonable to conclude that he had a direct acquaintance with Panini's work. As far as I am able to discern upon rereading Saussure's Mémoire, however, it shows no direct influence of Paninian grammar. Indeed, on occasion, Saussure follows a path that is contrary to Paninian procedure."{{citation | author=George Cardona | journal=Journal of the American Oriental Society | volume=120 | number=3 | year=2000 | pages = 464–5 | jstor=606023 | title=Book review: {{IAST|Pâṇinis}} Grammatik| author-link=George Cardona }}{{cite journal |last=D'Ottavi |first=Giuseppe |year=2013 |title=Paṇini et le Mémoire |trans-title=Panini and the Memoir |url=http://arenaromanistica.uib.no/?document_id=84 |journal=Arena Romanistica |volume=12 |pages=164–193}} (reprinted in {{cite book |url=http://www.lambert-lucas.com/livre/de-lessence-double-du-langage-et-le-renouveau-du-saussurisme/ |title="De l'essence double du langage" et le renouveau du saussurisme |year=2016 |trans-title="On the double essence of language" and the revival of Saussurism}}).

Pāṇini's grammar is the world's first formal system,{{Citation needed|date=May 2024}} developed well before the 19th century innovations of Gottlob Frege and the subsequent development of mathematical logic. In designing his grammar, Pāṇini used the method of "auxiliary symbols", in which new affixes are designated to mark syntactic categories and the control of grammatical derivations.{{clarify|date=December 2022}} This technique, rediscovered by the logician Emil Post, became a standard method in the design of computer programming languages.Bhate, S. and Kak, S. (1993) Panini and Computer Science. Annals of the Bhandarkar Oriental Research Institute, vol. 72, pp. 79-94.{{Citation |author=Kadvany, John |title=Positional Value and Linguistic Recursion |journal=Journal of Indian Philosophy |volume=35 |issue=5–6 |pages=487–520 |year=2007 |postscript=. |citeseerx=10.1.1.565.2083 |doi=10.1007/s10781-007-9025-5 |s2cid=52885600}} Sanskritists now accept that Pāṇini's linguistic apparatus is well-described as an "applied" Post system. Considerable evidence shows ancient mastery of context-sensitive grammars, and a general ability to solve many complex problems. Frits Staal has written that "Panini is the Indian Euclid."{{Cite book |last=Frits |first=Staal |url=http://eprints.nias.res.in/435/1/L1-2005.pdf |title=What Euclid is to Europe, Panini is to India - Or Are They? |date=6 May 2005 |publisher=National Institute of Advanced Studies |isbn=81-87663-57-X}}

Two literary works are attributed to Pāṇini, though they are now lost.

• The Jāmbavati Vijaya is a lost epic poem cited by Rajashekhara in Jalhana's Sukti Muktāvalī. A fragment of this work can be found in Ramayukta's commentary on the Namalinganushasana. The title suggests that the work dealt with Krishna's winning of Jambavati from the underworld as his bride.{{Cite book |last=Mukherjee |first=Sujit |author-link=Sujit Mukherjee |url=https://books.google.com/books?id=YCJrUfVtZxoC&dq=jambavati+vijaya+panini&pg=PA144 |title=A Dictionary of Indian Literature: Beginnings-1850 |date=1998 |publisher=Orient Blackswan |isbn=978-81-250-1453-9 |pages=144 |language=en}} Rajashekhara is quoted thus in Jalhana's Sukti Muktāvalī:

: नमः पाणिनये तस्मै यस्मादाविर भूदिह।

: आदौ व्याकरणं काव्यमनु जाम्बवतीजयम्॥

: namaḥ pāṇinaye tasmai yasmādāvirabhūdiha।

: ādau vyākaraṇaṃ kāvyamanu jāmbavatījayam॥

• Ascribed to Pāṇini, the Pātāla Vijaya (Victory in/over the Underworld) is a lost work cited by Namisadhu in his commentary on the Kavyalankara (Poetic Aesthetics) of Rudrata. The Pātāla Vijaya is considered the same work as the Jāmbavati Vijaya by Moriz Winternitz.{{Cite book |last=Winternitz |first=Moriz |author-link=Moriz Winternitz |url=https://books.google.com/books?id=gO1l_5WP8N8C&q=patala+vijaya+panini |title=History of Indian Literature: pt. 1.

There are many proto-mathematical concepts found in Pāṇini's works. Pāṇini came up with a plethora of ideas to organize the known grammatical forms of his day in a systematic way.{{Cite book |last=Joseph |first=George Gheverghese |author-link=George Gheverghese Joseph |url=https://books.google.com/books?id=XIj4DAAAQBAJ&dq=panini+mathematical+grammar&pg=PA135 |title=Indian Mathematics: Engaging With The World From Ancient To Modern Times |date=2016-07-28 |publisher=World Scientific |isbn=978-1-78634-063-4 |pages=135–136 |language=}}{{Cite book |last=Plofker |first=Kim |author-link=Kim Plofker |url=https://books.google.com/books?id=DHvThPNp9yMC&dq=panini+mathematical+grammar&pg=PA54 |title=Mathematics in India |date=2009-01-18 |publisher=Princeton University Press |isbn=978-0-691-12067-6 |pages=54 |language=en}} Like any mathematician who models a known phenomenon in mathematical language, Pāṇini created a metalanguage which is very close to the modern-day ideas of algebra.{{Cite book |last=Bhaskar Kompella |url=http://archive.org/details/panini-article-for-pub |title=Mathematical Structures in Panini's Ashtadhyayi |date=2019-09-30}}{{Cite book |last=Kornai |first=András |author-link=András Kornai |title=Mathematical linguistics |date=2008 |publisher=Springer Publishing |isbn=978-1-84628-985-9 |series=Advanced information and knowledge processing |location=London |pages=75}}{{Cite journal |last=Petersen |first=Wiebke |date=7 June 2004 |title=A Mathematical Analysis of Pānini's Śivasūtras |url=https://user.phil.hhu.de/~petersen/paper/petersen_jolli_proof.pdf |journal=Journal of Logic, Language and Information |language= |volume=13 |issue=4 |pages=471–489 |doi=10.1007/s10849-004-2117-7 |issn=0925-8531}}
