Nyah Kur language

Nyah Kur (ɲɑ̤h kur) is spoken by a few thousand people in the central and northeastern provinces (Sidwell 2009:113-114). According to Premsrirat (2002), there are 4,000 to 6,000 speakers of Nyah Kur, the vast majority living in Chaiyaphum Province. The northern dialects of Phetchabun Province are highly endangered.

Southern dialects

• Chaiyaphum Province
• Nakhon Ratchasima Province (Dan Khun Thot District, Pak Thong Chai District, and Khong District)

Northern dialects

• Phetchabun Province (Ban Thaduang, etc.)
• Phitsanulok Province (Nakhon Thai District)

The northern-southern bipartite classification is from Theraphan L-Thongkum's 1984 multi-dialectal Nyah Kur dictionary. However, Gerard Diffloth considers Nyah Kur to be made up of three dialects, namely North, Central, and South.

Being the only languages of the Monic branch of the Mon–Khmer language family, Mon and Nyah Kur are very closely related.

The modern-day speakers of Nyah Kur are the descendants of the Mon who did not flee west when the Khmer overran their empire in the 9th and 11th centuries. Consequently, modern Mon and Nyah Kur have both developed directly from Old Mon independently for almost a millennium.

Nyah Kur was discovered by linguists early in the 20th century, but was not recognized as being related (in fact a "sister" language) to Mon for nearly 70 years.

Due to integration into Thai society, the number of speakers of Nyah Kur as a first language is rapidly decreasing and some predict the language will become extinct within the next century unless the current course is reversed. Language change influenced by Thai is also occurring as younger generations pronounce certain phonemes different from older generations. For instance, final -/r/ and -/l/, which do not occur as finals in Thai, are now often pronounced as -[n] by younger generations (Premsrirat 2002). However, since the younger generations also generally have positive attitudes about their language and support the idea of having an orthography for Nyah Kur, the language may be preserved (Premsrirat 2002).
