The local vernacular term for the Urarina is Shimaku,[3] which is considered by the Urarina to be pejorative, as it is a Quechua term meaning "unreliable".[4] The ethnonym "Urarina" may be from Quechua--uray meaning below, and rina referring to runa, or people. Urarina is rendered in Quechua as uray-runa or people from below or down stream people.[5]
