செந்தமிழ்ச்
சொற்பொருட்
களஞ்சியம்

தமிழ், உலகின் மிகப் பழமையான செம்மொழிகளில் ஒன்று — இரண்டாயிரம் ஆண்டுகளுக்கும் மேலான இலக்கிய மரபு, இலக்கண அமைப்பு, கல்வெட்டு வரலாறு ஆகியவற்றை ஒருங்கே தாங்கி நிற்கும் ஓர் அரிய மொழிப்பேழை. அம்மொழியின் சொல்வளத்தை — வேர் முதல் வழிவந்த வடிவங்கள் வரை — தொகுத்து ஆவணப்படுத்துவதே இந்த செந்தமிழ்ச் சொற்பொருட் களஞ்சியம் (Classical Tamil Digital Lexicon) திட்டத்தின் நோக்கமாகும்.

Tamil, one of the world's most ancient classical languages, carries within it over two millennia of literary excellence, grammatical precision, and living oral tradition. The Sentamiḻc Corpoṟuṭ Kaḷañciyam — this Comprehensive Digital Lexicon of Classical Tamil — represents the Central Institute of Classical Tamil's most ambitious lexicographic endeavour: a systematic documentation of every word from the classical corpus, from its root form through all derivative variants, with citations drawn from over 300 source texts spanning Sangam poetry, epics, grammatical treatises, devotional literature, inscriptions, and regional oral tradition.

Guided by the three commandments of Tolkāppiyar — that every word carries meaning, that meaning is never self-evident, and that enquiry into meaning is boundless — this lexicon honours both the spoken vernacular (vaḻakku) and the poetic canon (ceyyuḷ) as equally authoritative sources of word-knowledge. It documents over 150 regional dialect zones, recovers words absent from standard dictionaries, and integrates the wisdom of foundational scholars including Pāvāṇar, whose life's work illuminated the deep phonological and etymological architecture of Tamil.

Through its Digital and AI-driven interface, this archive ensures that the vast corpus of Classical Tamil knowledge is made accessible to scholars, students, and enthusiasts across the world — blending centuries of academic scholarship with the possibilities of modern technology. It is my privilege to commend this work to all who love the Tamil language, and my earnest hope that it will serve as an enduring resource for future generations.
