Suansu is a language studied by Ivani, Jessica Katiuscia 2019 which is likely related (p.c. Jessica Ivani 2019 and p.c. Matthew Dryer 2023) to the nuclear Tangkhulic languages ( David R. Mortensen 2003 ). It is by far not close enough to be intelligible with any of the other nuclear Tangkhulic languages or East Tusom (p.c. Jessica Ivani 2019 and p.c. Matthew Dryer 2023).
