Tolkappiyar

Almost nothing is known about Tolkappiyar as a historical person; he is known entirely through his foundational text, the Tolkappiyam. The name "Tolkappiyar" means "he of the ancient composition," suggesting it might be a title rather than a birth name, possibly derived from his clan name. Traditional accounts, particularly in the preface to the Tolkappiyam, identify him as one of the twelve disciples of the sage Agastya and a prominent scholar of the Second Sangam academy. The text notes that Tolkappiyar was among fifty-nine poets, including Vellur Kappiyan and Sirupandaranganar, who flourished in the Second Sangam. While these biographical details are largely legendary, the existence and extraordinary nature of the Tolkappiyam as the oldest surviving Tamil document are undeniable. His religious affiliation is debated: scholars like Thiru. Vaiyapuri Pillai suggest he was a Jain or Buddhist, while Mahavidwan Ra. Raghavaiyangar posits he was a follower of the Vedic tradition, adhering to the 'Veda Vazhakku' (Vedic tradition). Due to these conflicting views, a definitive religious identity for Tolkappiyar cannot be established.

Tolkappiyam's signature lies in its systematic and comprehensive approach to Tamil grammar, divided into three principal sections: Ezhuttatikaram (Phonology/Orthography), Sollatikaram (Morphology/Syntax), and Porulatikaram (Poetics/Semantics). Each section comprises nine 'Iyal' (chapters). Ezhuttatikaram meticulously details the phonological structure of Tamil, including the articulation of sounds ('Pirappiyal'), which is noted for its ability to represent sounds from other languages as well, a feature considered unique and extensive. Sollatikaram addresses the morphology and syntax of words, explaining how letters form words. Porulatikaram, unique among ancient grammars globally, delves into the semantic and aesthetic principles governing Tamil poetry, particularly focusing on the 'Akam' (inner life, love) and 'Puram' (outer life, war, ethics) divisions. Tolkappiyar's methodological approach involves stating general rules ('Poduvithi'), followed by specific rules ('Sirappuvithi'), and then supplementary rules ('Puranadai') for exceptions or omissions. A key innovation is the 'tinai' system, which categorizes landscapes and their associated human emotions and behaviors: Kurinji (mountains, union), Mullai (forests, patient waiting), Marutam (farmlands, lovers' quarrels), Neytal (seashore, separation), and Palai (wastelands, elopement/separation). He also established the foundational rule for Akam poetry that characters should not be named: 'Makkaḻ nutaliya akaṉaintiṇaiyum suṭṭi oruvar peyarkoḷap peṟāar' (In the five Akam tinais concerning people, no one's name shall be mentioned), emphasizing the universal applicability of the themes.

Tolkappiyam stands as the foundational text for all subsequent Tamil grammar and literary theory, with later grammars consistently adopting its methodological approach of general, specific, and supplementary rules. Its depth and systematic analysis, particularly in phonetics ('Pirappiyal'), are often compared favorably to Panini's Ashtadhyayi, with some scholars asserting that even the 'emperor of grammar' in the Sanskrit tradition did not conduct such extensive research in certain areas. The emphasis on 'Uripporul' (human emotions and actions) over 'Muthal' (time and place) and 'Karupporul' (elements of nature) became a cornerstone of Tamil poetics, influencing how poets depicted the relationship between humanity and the natural world. Tolkappiyam's insistence on realism and the absence of 'grammar-less imagination' ('etthunaiyum porutkisaiyum ilakkanamil karpanaiyai') in Sangam literature highlights its commitment to depicting reality as it is perceived and understood. The work's enduring influence is such that, as noted by scholars, understanding Sangam literature is impossible without Tolkappiyam, and vice-versa, making it indispensable for comprehending the evolution of Tamil literary thought and the unique characteristics of Tamil literary culture.
