Kamas language

Kamassian (Kamas) is an extinct language once spoken in Russia by the Kamassins, north of the Sayan Mountains. It belongs to the Samoyedic branch of the Uralic language family, in the Kamass–Selkup group. The language disappeared with the death of its last native speaker, Klavdiya Plotnikova, in 1989, though a few people still know some words or phrases.

There were two dialects: Kamass (also called Kamass) and Koibal. Koibal is poorly documented—only about 600 words are known—and Koibal speakers shifted to the Turkic Khakas language. Modern Koibal people are now a mix of Samoyed, Khakas, and Yeniseian heritage.

The Kamassins were a small, nomadic group who lived beside Turkic and Yeniseian peoples. In the 17th century they began assimilating with Turkic groups, and by the 20th century the use of Kamass had declined as Russian influence grew. The language was studied by researchers starting in the 18th century, notably Castrén and Kai Donner. In 2016 the University of Tartu published an online Kamassian course, and researchers recorded about 1,550 words. The grammar and core vocabulary are well documented. In 2024 the Russian Geographical Society published a Kamassian learning book to support revival efforts.

Language structure at a glance
- Phonology: Kamassian had a relatively simple sound system with some variation between speakers. It allowed palatal sounds and some sounds found in loanwords. The language could have a few complex features, but overall its phonology is described as basic. The maximal syllable structure is CVCC. In the end of a syllable, the only allowed consonant cluster is a glottal stop plus a consonant (ʔC). Some sounds did not occur at the start of words. Palatalization occurred mainly before vowels. Comparisons between speakers show small differences in pronunciation.
- Morphology: Kamassian is agglutinative, using many affixes. It has seven grammatical cases and a variety of endings to mark things like number and tense. The plural endings appear in several allomorphs: -zaŋ, -zeŋ, -saŋ, -seŋ, with a few irregular forms for some nouns (for example words meaning “child,” “children,” or “moose” have special forms).
- Verbs and syntax: Kamassian has several tenses and moods, including present, past, future, conditional, imperative, and optative. The conditional is formed with endings that attach after vowels or consonants, often with a following -ze. Verbs can be negated with a special marker (e or i) used with the verb.
Deverbal nouns use the ending -š, and instrumental nouns use endings like -zan or -zǝn. The language also forms many derived words through affixes.
- Word order and grammar: Kamassian follows a subject–object–verb (SOV) order. It uses postpositions (not prepositions), and the head of a postposition is usually marked with a genitive ending. The subject is in the nominative case; objects are marked differently depending on definiteness. There is no complex system of conjunctions in typical usage; simple sentences often carry meaning that would be expressed with several clauses in other languages, sometimes using gerundive verb forms to indicate manner or time. Sentences require subject and predicate to agree in person and number.
- Pronouns and agreement: Subjects and predicates must agree in person and number. Noun modifiers (demonstratives, numerals) can also function as part of the noun phrase. There are no prepositions; instead postpositions are used, and many relationships are shown by case endings.

Revival and ongoing work
Although Kamassian is extinct as a spoken language, scholars continue to study and document it. Modern revival efforts include educational materials and courses, such as the Kamassian e-learning book and a 2024 revival publication, aimed at teaching some of the language to enthusiasts and researchers.

Kamassian is a striking example of how a small language can be rich in structure and history, and it remains the subject of ongoing study and revival efforts despite its extinction as a spoken language.
