The Aiton language or Tai Aiton language is spoken in Assam, India, in the Dhonsiri Valley and the south bank of the Brahmaputra. It is currently classified as a threatened language, with fewer than 2,000 speakers worldwide. Its other names include Aitonia and Sham Doaniya.[3]

Classification[edit | edit source]

The Aiton language is a part of the Southwestern branch of the Tai family of languages. It is closely related to, and sometimes considered a dialect of, Shan. There are three other actively spoken languages of this branch in Assam: Khamti, Phake, and Khamyang.[4]

History[edit | edit source]

The Tai languages in Assam share many grammatical similarities, a writing system, and much of their vocabulary.[5] The most prominent differences between the languages are their tonal systems.[4]

According to the oral and written records of the Aiton people, they originated from a place named Khao-Khao Mao-Lung, a Burmese state near the Chinese border.[6] It is generally believed that they came to India about two or three hundred years ago, seeking refuge from oppression.[6] Despite how long they have been in Assam, many members of the older generations are not fluent in Assamese, the official language of the state.[7]

Geographic Distribution[edit | edit source]

Aiton is spoken predominantly in India, in the northeastern state of Assam.

According to Morey (2005), Aiton is spoken in the following villages:
