Katawixi (Catawishi) is a Katukinian language formerly spoken in Amazonas, Brazil. It is nearly extinct among the known populations of Katawixi people, though an uncontacted group nearby may be Katawixi-speaking. Only a handful of isolated tribes still speak this language.
The following wordlist of Katawixi is taken from Loukotka (1949), which republishes a 1921 manuscript.
