Cracking the Code: A Scientific Model for Decoding the Indus Script

This study presents a data-driven framework for interpreting the undeciphered Indus script through structural modelling and frequency-based analysis. Drawing on Mahadevan's 1977 Concordance of approximately 3,700 inscriptions, the research identifies the most frequently occurring symbols, categorizes them thematically, and analyzes their positional behaviour to propose provisional syntactic roles-Starter, Middle, and Ender. A co-occurrence matrix was constructed to examine directional symbol pairings, revealing repeated, non-random structures that suggest systemic organisation. This model diverges from prior non-linguistic theories by demonstrating internal consistency, thematic grouping, and syntactic regularity within the script. The resulting framework is hypothesis-generating, not a confirmed decipherment, offering a replicable approach for future interdisciplinary validation across archaeology, linguistics, and computational modelling.
