Evaluating the “tamil as the mother of all languages” claim: a methodological framework

This article contributes to the study of language-origin narratives. Using the claim that Tamil is the “mother of all languages” as a case, it shows how scholars can classify and evaluate linguistic, historical, literary, political, and popular materials without reducing the inquiry to a true-or-false question. The aim is not to prove or disprove a universal-origin proposition, but to identify evidence required to evaluate each component and trace how discourse acquires authority. A structured integrative review assembled 64 sources across historical and comparative linguistics, Dravidian and South Asian contact studies, Tamil cultural history, language ideology, review methodology, and political discourse. Sources were screened for relevance, scholarly standing, methodological value, and disciplinary balance, then coded as evidentiary claims, inferential assumptions, ideological functions, and explanatory limits. The procedure is transparent and auditable, although not fully reproducible because search records were not retained. The evaluation finds strong support for Tamil’s documentary depth, literary continuity, and importance within Dravidian reconstruction. Contact claims require case-specific historical evidence, proposed long-range relationships remain unresolved, and available evidence does not establish historical Tamil as the universal ancestor of human languages. The article proposes a graded, contact-sensitive framework distinguishing family-supported, contact-supported, typologically parallel, computationally suggestive, and primarily symbolic claims.
