>>213842685 (OP) Sikkimese isn't an ethnicity retard. The Sikkimese population comprises of multiple ethnic groups like rai, limboo, nepali, lepcha, bhutia etc. and nepali is the lingua franca in Sikkim. Also you can't distinctly say which ethnic groups are Nepali because everyone speaks that language here.
