[2] The French first record the Kichai people's presence along the upper Red River in 1701.
Kitsai's consonant inventory consists of the phonemes shown in the chart below.
There are a few instances where /o(ː)/ does not occur next to /k/, like the word for "owl" (pronounced /oːs/), but this is rare.

[8] In the 1960s, Lesser shared his materials with Salvador Bucca of the Universidad Nacional de Buenos Aires, and they published scholarly articles on Kitsai.
