The Tholkappiyam is the oldest surviving Tamil grammar, and its name is all over Chennai: on the 58-acre Tholkappia Poonga eco park in Adyar, on the top national award for classical Tamil scholarship, and in the state’s own policy notes, which cite it as evidence of the language’s age. It has 1,610 verses, called nurpas, set out in three books of nine chapters each, according to the reference site Tamil.wiki.
You do not need to be a scholar to get a sense of it. This guide explains how the work is organised, what each part covers, how old it may be and where Chennai readers can find it, in Tamil and in other languages.
Three books, 27 chapters
The Tholkappiyam is divided into three athikarams, each with nine iyals (chapters).
| Book | What it covers | Example chapters |
|---|---|---|
| Ezhuthathikaram (letters) | Sounds and letters, how they are produced and how they combine when words join | Nul Marabu, Pirappiyal, Punariyal |
| Sollathikaram (words) | Nouns, verbs, case, particles and how words form sentences | Kilaviyakkam, Vetrumai Iyal, Peyariyal, Vinai Iyal |
| Poruladhikaram (subject matter) | The themes and conventions of poetry: love (akam), war and public life (puram), emotions, simile, prosody | Akaththinaiyiyal, Puraththinaiyiyal, Meyppattiyal, Seyyuliyal |
The third book is what makes the Tholkappiyam unusual. It is not only a rulebook for spelling and grammar but also a guide to how classical Tamil poetry was meant to work. The EBSCO research summary notes that it divides subject matter into the inward world of home and love and the outward world of public affairs, and describes five land regions, each with its own music, gods and customs. These are the ideas that underlie the Sangam anthologies.
How old is it?
Nobody knows for certain. Estimates by scholars range from very early dates to the 6th century CE, and there is no firm evidence about the author’s life, Tamil.wiki says. It reports that the most commonly accepted view places the work between about the 2nd century BCE and the 1st century CE. The EBSCO summary gives about 250 BCE. Treat any single date you see as one scholar’s estimate.
The author is known as Tholkappiyar. Very little is known about him beyond the name.
The commentators
Much of what readers know about the Tholkappiyam comes through medieval commentaries. Ilampuranar wrote the first commentary on the whole work. He was followed by Senavaraiyar, Theivachilaiyar, Naccinarkkiniyar, Perasiriyar and Kalladar, who commented on different parts. Modern editions often name the commentator in the title, so a book labelled “Ilampuranar urai” contains his commentary alongside the verses.
Where Chennai meets the Tholkappiyam
- Tholkappia Poonga, Adyar. The restored 58-acre Adyar Creek site off Greenways Road is run by the Chennai Rivers Restoration Trust. Walkers with a verified pass may visit Monday to Saturday, except public holidays, from 6.30 to 8 am and 4.30 to 6 pm, the CRRT page says. Children under 18 are not allowed. A 2021 government release says application forms are on the CRRT website or at its Raja Annamalai Puram office.
- The Tholkappiyar Award. The lifetime achievement prize among the Presidential Awards for Classical Tamil carries ₹5 lakh, says a Ministry of Education release.
- State policy. The Tamil Development Department’s 2024-25 policy note cites the Tholkappiyam when it describes Tamil’s antiquity.
Reading it in Tamil and other languages
- Translations. On 2 December 2025, a multilingual translation in 10 languages, including Odia, Assamese, Urdu and Tulu, was released at Kashi Tamil Sangamam in Varanasi, according to a PTI report in The Week. The report placed the release among the translation projects of the Central Institute of Classical Tamil, which is based in Chennai.
- Digital tools. The Tamil Virtual Academy released a Tholkappiyam information tool among 12 free Tamil software packages between 2017 and 2018, the state IT department says.
- Libraries. The Tamil Digital Library at tamildigitallibrary.in hosts scanned editions and commentaries. Public libraries and Tamil bookshops in Chennai stock printed editions with modern prose explanations, which are the easiest place for a beginner to start.
The work also turns up in Tamil Nadu school textbooks, where short extracts are used to explain grammar rules, so many Chennai students meet a few nurpas long before they open the full text. A practical tip for adult readers: start with the Sollathikaram, which deals with words and sentences in ways a school student will recognise, before trying the Poruladhikaram’s poetic theory.
