The Koibal dialect is a dialect of the Kamas language or arguably another independent Sayan Samoyed language. About 600 words of the Koibal dialect are known, but there are no grammatical descriptions of Koibal. The vocabulary of Koibal is very similar to Kamas proper. The Koibal dialect died around the 19th century. The Koibals assimilated into Turkic tribes. There was a Koibal-Russian glossary published in 1806. It is possible that it has a SOV word order, as so does Kamas.
