Voiceless retroflex stop to Voiceless alveolar plosive
The shift from a retroflex stop [ʈ] to an alveolar stop [t] is a form of de-retroflexion involving apical displacement—moving from postvocalic to prevocalic position while fronting from the hard palate to the alveolar ridge. This process is well-documented in South Dravidian languages (Telugu, Kannada) where Proto-Dravidian retroflex stops underwent systematic repositioning and deretroflexion, and is a common phonological simplification in languages with marginal retroflex series.

Language Examples
Proto-Dravidian *ṭ (retroflex stop, postvocalic position)→Telugu and Kannada /t/ or [ɖ] → [d] (prevocalic)— Major apical displacement: retroflex stops shifted from postvocalic to prevocalic position, often deretroflexing to alveolar [t] or voiced [d]. Proto-Dravidian *uẓ-u 'plow' → Telugu ḍu-kki; *car-a-cu → Telugu trācu.
Proto-Dravidian */ṭ/, Kannada historical /ʈ/→Modern Kannada /t/ (in merged system)— Kannada merged the three-way coronal distinction into two-way dental-retroflex, with many retroflex stops dentalizing to [t].
Proto-Dravidian *ṭ→Tamil /ṭ/ (largely preserved, but some dialects show [t] variants)— Unlike Kannada/Telugu, Tamil preserved the retroflex-dental distinction more robustly, though some dialects show deretroflexion.
ṣṭ [ʂʈ] (Sanskrit)→tt [t̪t̪] / [tt]— Historical simplification where retroflex clusters fronted to dental or alveolar geminates.
[ʈ] (marginal)→[t]— Ongoing de-retroflexion in younger speakers who neutralize the contrast between alveolar and retroflex stops.
