Bora–Witóto (also Bora–Huitoto, Bora–Uitoto, or, ambiguously, Witotoan) is a proposal to unite the Bora and Witotoan language families of northeastern Peru (Loreto Region), southwestern Colombia (Amazonas Department), and western Brazil (Amazonas State). Kaufman (1990) found the proposal plausible; by 1994 he had accepted it and added the Andoque language.
- Boran (AKA Bora–Muiname, Bóran, Miranyan, Miranya, Bórano)
- Witotoan (AKA Huitoto–Ocaina, Huitotoan, Huitotoano, Witóto, Huitoto, Uitoto, Huitótoano)
- Ocaina (AKA Okaina)
- Witoto Proper
- Nïpode (AKA Nüpode, Nipode Huitoto, Nipode Witoto, Witoto Muinane, Muinane Huitoto, Muiname)
- Nonuya (AKA Nyonuhu, Nonuña, Achote, Achiote) Loreto, Peru
The classification above is based on Campbell (1997) who follows Richard Aschmann's 1993 classification and reconstruction of proto-Witotoan.
Kaufman (1994) lists Bóran and Witótoan (Huitoto–Ocaina) as separate families (they are grouped together with Andoque as Bora–Witótoan; by 2007 he moved Andoque to Witotoan). He does not show internal branching. Nipode and Mïnïca are listed as dialects of a single Meneka language (whereas Aschmann and Campbell treat these as separate languages at different branch nodes). Kaufman also includes within his Witótoan (Huitoto–Ocaina) the following extinct languages :
- Andoquero (AKA Andokero, Miranya-Karapana-Tapuyo, Miraña, Carapana) Amazonas, Colombia (†) – listed as a living Tucanoan language in Ethnologue 16
- Coeruna (AKA Koeruna) Amazonas, Brazil (†)
- Koihoma (AKA Coto, Koto, Orejón, Coixoma) Loreto, Peru (†) – listed as a living Tucanoan language in Ethnologue 16
Andoquero, Coeruna, and Koihoma are all extinct. Nonuya is nearly extinct, but attempts are being made at revival.
- The name Muiname has been used to refer to the Muinane language (Bora Muinane) of the Boran sub-group and also to the Nipode language (Witoto Muinane) of the Huitoto–Ocaina sub-group.
- The names Koto, Coto, and Orejón have been used to refer to the Koihoma language (Coixoma) and also to the unrelated Orejón language (also known as Koto or Coto) of the Tucanoan language family.
Kaufman's (1994) Bora–Witótoan stock includes the Bóran and Witótoan (Huitoto-Ocaina) sub-families and also the endangered language isolate Andoque (Andoke). By 2007 he had moved Andoque to within the Witotoan branch, and included Bora–Witoto in his Macro-Andean proposal. Richard Aschmann (1993) considered Andoque an isolate. Gildea and Payne (2007) checked Bora-Witoto with Andoque, Proto-Cariban and Yagua, and found Bora-Witoto to be not related to any of the others, including Andoque. Joseph Greenberg included Bora–Uitoto within his Macro-Carib phylum, but this has not been followed by linguists working on those families.
