Etymology
Combès (2012) suggests that -''toki'' ~ -''tuki'' ~ -''tuke'' (also present in the ethynonym '' Gorgotoqui'') is likely related to the Bororo animate plural suffix -''doge'' (i.e., used to form plural nouns for ethnic groups). Hence, the name ''Otuqui'' (''Otuke'') was likely etymologically related to the name '' Gorgotoqui''.Combès, Isabelle. 2012. Susnik y los gorgotoquis. Efervescencia étnica en la Chiquitania (Oriente boliviano), p. 201–220. ''Indiana'', v. 29. Berlín.Other varieties
