The Yugur Alphabet

Yugur and Yughur are alternate spellings of the same language ^[2]. Both refer to the Western Yugur Turkic language of the Western Yugur people of Sunan Yugur Autonomous County, Gansu, China. The language is also known as Sarïgh Uyghur (Yellow Uyghur). All names share the same ISO 639-3 code: ybe.

The spelling "Yugur" appears frequently in Chinese-context academic literature reflecting the Chinese romanisation Yugur (裕固, Yùgù). The spelling "Yughur" is used in Turkological and linguistic literature. Both spellings describe the same severely endangered Kipchak Turkic language spoken by approximately 4,600 Western Yugur people in the Qilian Mountain region of Gansu.

Yugur/Yughur and Uyghur are entirely different languages ^[1] despite the similar names. Uyghur is spoken by over 10 million people in Xinjiang and uses an Arabic-based script. Yugur/Yughur is spoken by fewer than 5,000 people in Gansu and uses a Latin-based script. They are both Turkic languages but belong to different Turkic branches.

The name similarity reflects a shared historical origin: both communities descend from the ancient Uyghur Khaganate. After its collapse in 840 CE, some groups fled south to Gansu (becoming the Western Yugur / Sarïgh Uyghur people). But the languages diverged significantly over more than a millennium — Uyghur developed as a Karluk Turkic language in Xinjiang while Yugur/Yughur preserved Kipchak Turkic features in its isolated Gansu mountain homeland.

Western Yugur (Yughur) is spoken by approximately 4,600 people — exclusively among the Western Yugur ethnic group of Sunan Yugur Autonomous County, Gansu Province, China. The total Western Yugur ethnic population is around 10,600, meaning fewer than half the ethnic group still speaks the language. It is classified as severely endangered by UNESCO.

Language shift to Mandarin Chinese has been rapid across younger generations. Most fluent speakers today are elderly, making intergenerational transmission extremely limited. Revitalisation efforts face challenges from geographic isolation, small speaker communities, and the absence of a widespread written standard for the spoken vernacular.

The Western Yugur (Yughur) language uses a 32-letter Latin alphabet developed by linguists for documentation and literacy purposes. It includes 8 vowel letters — including special letters with diacritics such as Ä, Ö, Ü, and Ë — to represent the vowel harmony system characteristic of Turkic languages.

Historically, Yugur communities did not have a standardised writing system. The Latin-based script was devised primarily in the 20th century for linguistic analysis and educational use. In everyday life, Western Yugur speakers use Mandarin Chinese characters for writing. The Latin transcription system is mainly found in academic publications and linguistic fieldwork materials.

Yugur / Yughur is spoken in Sunan Yugur Autonomous County, located in Zhangye City, Gansu Province, northwestern China. The county lies in the Qilian Mountain corridor — the narrow strip of land between the Tibetan Plateau and the Gobi Desert historically known as the Hexi Corridor.

This region was a strategic route on the ancient Silk Road and served as a refuge for ancestors of the Western Yugur people after the collapse of the Uyghur Khaganate in the 9th century CE. The harsh terrain and relative isolation helped preserve the language for over a millennium, though modern infrastructure and Mandarin-medium schooling have accelerated language shift in recent decades.

Western Yugur (Yughur) belongs to the Turkic language family, specifically the Kipchak branch (also called Northwestern Turkic). This places it in the same broad group as Kazakh, Kyrgyz, and Tatar — not in the Karluk branch that includes Uyghur and Uzbek, despite the name similarity. ^[1]

Within the Kipchak branch, Western Yugur occupies an isolated position, having developed in geographic separation from other Kipchak languages for over 1,000 years. It preserves archaic Turkic features lost in most related languages, making it of particular interest to comparative Turkologists studying the historical development of the Turkic language family.

Yugur / Yughur is a Turkic language and is not related to Chinese (Sino-Tibetan) or Tibetan (Tibeto-Burman) in terms of genetic classification or grammar. However, centuries of geographic proximity and contact have resulted in significant lexical borrowing into Yugur from both Mandarin Chinese and Tibetan.

Many Western Yugur speakers are multilingual — fluent in Mandarin, and sometimes Tibetan, in addition to their Turkic mother tongue. This language contact has influenced Yugur phonology, vocabulary, and even sentence structure to some degree. The heavy Chinese influence is one reason why Yugur is often studied as a prime example of Central Asian contact linguistics.

The Western Yugur people descend from the ancient Uyghur Khaganate, a powerful Turkic empire centred on the Mongolian steppe that flourished from 744 to 840 CE. When the Khaganate collapsed under Yenisei Kirghiz attacks, various Uyghur groups fled in different directions. One group migrated south into the Gansu Corridor, eventually becoming the Sarïgh Uyghur ("Yellow Uyghur") — the ancestors of today's Western Yugur people.

They lived for centuries as semi-nomadic pastoralists in the Qilian Mountains, maintaining a distinct identity and language despite surrounding Tibetan, Mongol, and Chinese populations. Under the Ming and Qing dynasties they paid tribute to the Chinese court. In the 20th century the People's Republic of China established Sunan Yugur Autonomous County (1954) recognising them as a distinct ethnic group (裕固族, Yùgùzú).
