 The word Akuntsu is an exonym applied to the tribe by the Kanoê, who were contacted shortly before the Akuntsu, meaning roughly "other Indians".The nearby Tupari are also recorded as knowing of a group called the 'Akontsu' or 'Wakontsón' whom they had never visited.In both cases, the Akuntsu had a reputation for being "dangerous" and seemingly had little contact with neighbouring indigenous peoples.
