Nasalization Velarization Sino-Tibetan Mongolic

Alveolar trill to Velar nasal

The transformation from an alveolar trill ([r]) to a velar nasal ([ŋ]) is an attested phonetic shift, involving a significant change in both the place and manner of articulation. This process typically entails the point of articulation moving from the alveolar ridge to the velum, while the airflow mechanism changes from a trill (intermittent contact with the articulator) to a nasal (airflow through the nasal cavity with a complete oral closure).

Phonetic Effects
