Written Sinhala exhibits extreme diglossia when contrasted with colloquial speech. While spoken Sinhala has largely eliminated person, number, and gender inflection on finite verbs, formal literary Sinhala mandates strict grammatical agreement between nominative subjects and verbal predicates. This paper examines the algorithmic resolution of literary Subject-Verb Agreement (SVA) in the Sodupath NLP engine, outlining the rule-based finite-state methodology used to parse animacy, gender inflection, honorific markers, and tense concordance without over-relying on opaque neural approximations in low-resource environments.

In spoken contemporary Sinhala, the historical phonological distinction between dental nasals/liquids [n, l] and retroflex nasals/liquids [ɳ, ɭ] has completely merged. Native speakers articulate 'න' and 'ණ' as [n], and 'ල' and 'ළ' as [l]. Nevertheless, written Sinhala fiercely preserves the classical etymological distribution codified in treatises such as the Sidath Sangarawa. Consequently, orthographic errors involving ණ/න and ළ/ල constitute over 68% of all spelling infractions in digital Sinhala corpora. This paper details the computational disambiguation methods deployed in Sodupath to enforce etymological precision.
Segmentation & Tokenization

Standard tokenizers trained on Western European languages assume that whitespace strictly delineates word boundaries. In South Asian languages, especially Sinhala and Sanskrit, morphophonemic euphonic combinations (Sandhi) merge adjacent word boundaries, whilst colloquial writing often erroneously breaks indivisible compound morphemes or conjoins independent words with clitic particles. This paper presents the hybrid tokenization and Sandhi decomposition engine utilized in Sodupath to guarantee syntactically sound segmentation.

In Sinhala morphology, the terminal virama nasal marker Hal-Na ('න්' or suffix '-ුන්') functions polysemously across radically distinct grammatical roles: as an animate plural inflection (ගුරුවරුන්, මිනිසුන්), as an adjectival relative participle (දුන්, හුන්, රැඳුන්), as a root adjective (නොසන්සුන්, සන්සුන්), and as an inanimate singular mass noun (අසුන්, රන්, දන්, පින්). Naive morphological parsers invariably misclassify these tokens as plural subjects, inducing cascading Subject-Verb Agreement errors. This paper explains how Sodupath isolates nominative agent precedence to solve this anomaly.

South Asia encompasses over 1.8 billion speakers across Indo-Aryan and Dravidian language families. Despite their genetic divergence, centuries of areal contact have yielded profound structural convergence across phonology, morphology, and syntax. Simultaneously, South Asian digital scripts encounter severe hurdles with Unicode complex text rendering, Zero-Width Joiner (ZWJ) anomalies, and resource scarcity in modern large language models. This comparative treatise explores the shared challenges and computational methodologies binding Sinhala, Tamil, and Hindi digital processing.
