Shan language

Shan is the native language of the Shan people and is mostly spoken in Shan State, Myanmar. It is also spoken in pockets in other parts of Myanmar, in Northern Thailand, in Yunnan, in Laos, in Cambodia, in Vietnam and decreasingly in Assam and Meghalaya. Shan is a member of the Kra–Dai 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. The term Shan is also used for related Northwestern Tai languages, and it is called Tai Yai or Tai Long in other Tai languages. Standard Shan, which is also known as Tachileik Shan, is based on the dialect of the city of Tachileik.
In 2019, Ethnologue estimated there were 3.3 million Shan speakers, including 3.2 million in Myanmar. The Mahidol University Institute for Language and Culture estimates there are 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.

History

Historically, the dominance of Shan as a regional lingua franca made it the source of many loanwords in other regional languages, especially Jingpo and Palaung.

Influence from Burmese

By the same token, Shan has been significantly influenced by Burmese, mediated by centuries of historical and ongoing contact and exchange between Burmese and Shan speakers, especially between the Burmese royal court and Shan principalities. For instance, the lack of a sound in most Shan dialects is attributed to Burmese influence; this sound is present in the closely related Khün and Northern Thai languages. Shan vocabulary has been significantly enriched by Burmese contact, with Burmese loan words appearing throughout the Shan lexicon, including loanwords borrowed from Pali via Burmese. Burmese appears to have also influenced Shan grammar, with respect to the use of complex prepositions and certain word patterns that do not exist in closely related Tai languages.
Due to Shan's status as a lingua franca in the region, it has served as an intermediary, passing loanwords from Burmese into other regional languages.

Influence from Thai

Due to labour migration in recent decades, one million ethnic Shan now live in Thailand. As a result of ongoing language contact, Thai has increasingly become a competing source of loanwords into Shan, especially for scientific and political concepts. These Thai loanwords are often more difficult to detect, because of phonetic and structural similarities between Shan and Thai. Some recent phonological developments, like the reversal of the historical > shift especially among younger Shan speakers, is attributed to contact with Thai.

Names

The Shan language has a number of names in different Tai languages and Burmese.

In Shan, the spoken language is commonly called kwam tai. The written language is called lik tai.
In Burmese, it is called hram: bhasa, whence the English word "Shan". The term "Shan," which was formerly spelt hsyam: in Burmese, is an exonym believed to be a Burmese derivative of "Siam".
In Thai and Southern Thai, it is called phasa thai yai or more informally or even vulgarly by some phasa ngiao.
In Northern Thai, it is called kam tai or more informally or even vulgarly by some kam ngiao.
In Lao, it is called phasa tai yai or more informally or even vulgarly by some phasa ngiao.
In Tai Lü, it is called kam ngio.
Dialects

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 language 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 , and . 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.
J. Marvin Brown divides the three dialects of Shan State as follows:

Northern — Lashio, Burma; contains more Chinese influences
Southern — Taunggyi, Burma ; contains more Burmese influences
Eastern — Kengtung, Burma ; closer to Northern Thai and Lao

Prominent divergent dialects are considered separate languages, such as Khün, which is spoken in Kengtung valley. Chinese Shan is also called Tai Mao, referring to the old Shan State of Mong Mao. Tai Long is used to refer to the Southern Shan State dialect spoken in southern and central regions west of the Salween River, the Northern Shan State dialect, and the dialect spoken in Laos. There are also dialects still spoken by a small number of people in Kachin State, such as Tai Laing, and Khamti spoken in northern Sagaing Region.

Resources

Given the present instabilities in Burma, one choice for scholars is to study the Shan people and their language in Thailand, where estimates of Shan refugees run as high as two million, and Mae Hong Son Province is home to a Shan majority. The major source for information about the Shan language in English is Dunwoody Press's Shan for English Speakers. They also publish a Shan-English dictionary. Aside from this, the language is almost completely undescribed in English.
