Northern South America
Waimiri Atroari belongs to the Carib language family, which is centralized in Northern South America. The Carib languages in northern Brazil are fairly similar, while Waimiri-Atroari is rather different (Moore, 2006, 119). Carib can be categorized into three groups: Northwest Amazon, Guiana area and Upper Xingu Basin. Waimiri Atroari seems to fall into the second group, Guiana area (Bruno 2003, 16).
