Answer: Bengali
Notes: ‘Toto Shabda Sangraha’ Dictionary is set to be released to save Toto, a Sino-Tibetan language spoken by the tribal Toto people, from extinction. A language spoken by barely 1,600 people living in parts of West Bengal bordering Bhutan, is written in the Bengali script. Though Dhaniram Toto developed a script as recently as in 2015, most people either write it in Bengali script or write in Bengali language.
