Orari/ Eastern Boróro / Orarimugodoge - language spoken by an ancient warlike tribe on theValhas River,Garças River, andMadeira River, Mato Grosso. [Is a dialect of Bororo proper.]
Umutina/ Barbudo - spoken by a few families between theParaguai and Bugres Rivers, Mato Grosso.
Otuque/ Loushiru - spoken at the ancient mission ofSanto Corazon in the Bolivian Chaco, now by a few individuals.
The Bororoan languages are commonly thought to be part of theMacro-Jê language family.[1][2]: 547
Ceria & Sandalo (1995) note parallels between Bororo and theGuaicuruan languages.[13] Kaufman (1994) has suggested a relationship with theChiquitano language,[14] which Nikulin (2020) considers to be a sister ofMacro-Jê.[3] Furthermore, Nikulin (2019) has suggested that Bororoan has a relationship with theCariban andKariri languages:[15]
Jolkesky (2016) notes that there are lexical similarities with theGuato,Karib,Kayuvava,Nambikwara, andTupi language families due to contact.[17]
Cariban influence in Bororoan languages was due to the later southward expansion of Cariban speakers into Bororoan territory. Ceramic technology was also adopted from Cariban speakers.[17]: 415 Similarly, Cariban borrowings are also present in theKarajá languages. Karajá speakers had also adopted ceramic technology from Cariban speakers.[17]: 420
Similarities with Cayuvava are due to the expansion of Bororoan speakers into theChiquitania region.[17]: 416
