Tai peoples refers to the population of descendants of speakers of a common proto-Tai language, including sub-populations which no longer speak a Tai language. Some 8-10 million people in Northeast India (not limited to Assam) descent from Ahom people but may have intermarried with others and now speak Assamese. Additional tens of thousands in India speak Tai languages (mostly in Arunachal Pradesh). Aside from India, Tai peoples can generally be identified through their language.
