MTCN stands for Mother Tongue Center Nepal. It started in the year 2001 with translation of booklets into different mother tongues of Nepal on the social issues like, health, awareness and empowerment etc, developed by UMN in Nepali language. From 2002 onward, it has been further working on language development and education.

Now MTCN works for language documentation and orthography development ( A Mother Tongue Writing Guide), stretching further on for dictionary development and the literacy program in future to help ethnic minorities in the area of language development and to preserve endangered languages in Nepal.
