A South Indian (Malayalam) Evaluation of Sanskrit t and d

Summary

This linguistic study investigates how Malayalam grammarians have evaluated and adapted the Sanskrit dental and retroflex plosives represented by the letters “t” and “d” in their writing and pronunciation. The article begins by outlining the phonetic systems of Sanskrit and Dravidian languages, noting that while Sanskrit distinguishes between dental and retroflex sounds, early Malayalam lacked a distinct symbol for the retroflex plosive and often used the dental symbol for both. Drawing on grammatical treatises and manuscript evidence, the author describes efforts by medieval scholars in Kerala to refine orthography and introduce separate characters to represent retroflex consonants. The article compares lexical examples where Sanskrit loanwords with dental consonants were either retained or adapted to fit Malayalam phonology. It notes that in certain consonant clusters and intervocalic positions, Malayalam writers substituted the retroflex “ṭ” for the dental “t,” reflecting regional pronunciation. Tables in the article classify examples according to the position of the consonant and document contrasts in words like “sattva” and “paṭṭu.” The author analyses rules from works such as the Lilatilakam and other śikṣā texts, explaining how scribes employed diacritics or ligatures to differentiate sounds. The study points out that the variation was not uniform across dialects: west‑coast Malayalam dialects tended to innovate a new sign for retroflex “ṭ,” while east‑coast dialects preserved older conventions. The article also discusses the influence of Tamil orthography and the impact of Sanskritisation on Malayalam literary language. It concludes that the process of distinguishing the phonemes demonstrates a conscious linguistic evaluation by Malayalam scholars, reflecting a broader pattern of adapting Sanskrit linguistic categories to suit Dravidian phonology without sacrificing the phonemic richness of the vernacular.
