The Shan language is the native language of Shan people and spoken mostly in Shan State, Burma. It is also spoken in pockets of Kachin State in Burma, in northern Thailand, and decreasingly in Assam. Shan is a member of the Tai–Kadai language family, and is related to Thai. It has five tones, which do not correspond exactly to Thai tones, plus a "sixth tone" used for emphasis. It is called Tai Yai, or Tai Long in the Tai languages.
The number of Shan speakers is not known in part because the Shan population is unknown. Estimates of Shan people range from four million to 30 million, though the true number is somewhere around six million, with about half speaking the Shan language
