About Tholkaappiyam

Tolkāppiyam or Tholkaappiyam has 3 Adhikaarams. Each Adhikaaram has 9 Iyals in them. Each Iyal have a specific number of songs/paadal (or Sutrās). Songs are classified into Categories. If we analyse the songs as categories, it is easier to understand the core meaning of the Sutrās.

P. S. Subrahmanya Sastri

Subrahmanya Sastri was the first person to translate Tolkāppiyam into English. He worked on the Tolkappiyam, which he later translated into English. The translation of Ezhuthathikaram and Poruladhikaram were published by the Kuppuswami Sastri Research Institute, while Solladhikaram was published by Annamalai University. We have referred to Subrahmanya Sastri's text on Tholkaappiyam in Roman transliteration and English translation.

History of Tholkaappiyam

Tholkapiyam, some traditionally believe, was written by a single author named Tolkaappiyar, a disciple of Vedic sage Agastya mentioned in the Rigveda (1500–1200 BCE). His student Tholkaappiyar was asked to compile Tamil grammar, which is Tolkappiyam. In Tamil historical sources such as the 14th-century influential commentary on Tolkappiyam by Naccinarkkiniyar, the author is stated to be Tiranatumakkini (alternate name for Tolkappiyan), the son of a Brahmin rishi named Camatakkini. The earliest mention of Agastya-related Akattiyam legends are found in texts approximately dated to the 8th or 9th century. The dating of the Tolkappiyam is difficult, much debated, and it remains contested and uncertain. Proposals range between 5,320 BCE and the 8th century CE.
