Shan language  The Shan language (Shan written: , , Shan spoken: , or , ; , ; , ) is the native language of the Shan people and is mostly spoken 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, with about half speaking the Shan language. In 2001 Patrick Johnstone and Jason Mandryk estimated 3.2 million Shan speakers in Myanmar; the Mahidol University Institute for Language and Culture gave the number of Shan speakers in Thailand as 95,000 in 2006. Many Shan speak local dialects as well as the language of their trading partners. Due to the civil war in Burma, few Shan today can read or write in Shan script, which was derived from the Burmese alphabet. The Shan language has a number of names in different Tai languages and Burmese. The Shan dialects spoken in Shan State can be divided into three groups, roughly coinciding with geographical and modern administrative boundaries, namely the northern, southern, and eastern dialects. Dialects differ to a certain extent in vocabulary and pronunciation, but are generally mutually intelligible. While the southern dialect has borrowed more Burmese words, Eastern Shan is somewhat closer to northern Thai languages and Lao in vocabulary and pronunciation, and the northern so-called "Chinese Shan" is much influenced by the Yunnan-Chinese dialect. A number of words differ in initial consonants. In the north, initial and , when combined with certain vowels and final consonants, are pronounced (written "ky"), (written "khy") and (written "my"). In Chinese Shan, initial becomes . In southwestern regions is often pronounced as . Initial only appears in the east, while in the other two dialects it merges with . Prominent dialects are considered as separate languages, such as Khün (called Kon Shan by the Burmese), which is spoken in Kengtung valley, and Tai Lü. Chinese Shan is also called (Tai) Mao, referring to the old Shan State of Mong Mao.
