Deretroflexion Lenition Indo-Aryan

Voiced retroflex flap to Alveolar trill

The voiced retroflex flap [ɽ] shifts to the alveolar trill [r] through deretroflexion, a common historical sound change in Indo-Aryan languages. This transformation is well-documented in Sanskrit evolution to Modern Hindi and other Indo-Aryan varieties, where retroflex flaps acquire alveolar articulation in intervocalic and word-final positions.
