Retroflexion Assimilation Flapping Indo-Aryan Dravidian

Alveolar trill to Voiced retroflex flap

The alveolar trill [r] shifts to the voiced retroflex flap [ɽ] through retroflex harmony and assimilation in South Asian languages. This change is well-attested as both a historical sound law in Indo-Aryan languages (via the RUKI rule and subsequent retroflex spreading) and as contemporary allophonic variation in Hindi, Tamil, Telugu, Kannada, and other Dravidian and Indo-Aryan languages.
