Gorgotoqui is a currently undocumented extinct language of the Chiquitania region of the eastern Bolivian lowlands.
[1] Alternate spellings include Borogotoqui, Brotoqui, Corocoqui, Corocotoqui, Corocotoquy, Corogotoqui, Corotoque, Gorgotaci, Gorgotoci, Gorgotoquci, Gorogotoqui, Guorcocoqui, Jorocotoqui, Korchkoki, Orotocoqui.
A Jesuit priest[3] wrote a grammar, but no-one has been able to locate it "in recent years" (Adelaar & Muysken 2004:32), and no other documentation has survived.
Thus a language that was regionally important during the colonial era disappeared under pressure from more successful indigenous peoples (Adelaar 2007:326); this appears to have occurred in under half a century (Alarcón 2001:101).
Loukotka (1968) classified Gorgotoqui as a language isolate, but Kaufman (1990) left it unclassified because of a lack of data.
