Bororoan languages
The Borôroan languages of Brazil and Bolivia are Borôro and the extinct Umotína, Kovareka, Kuruminaka and Otuke. They are sometimes considered to form part of the proposed Macro-Jê language family, though this has been disputed.
They are called the Borotuke languages by Mason, a portmanteau of Bororo and Otuke.

The Bororoan languages are commonly thought to be part of the Macro-Jê language family.Ceria & Sandalo note parallels between Bororo and the Guaicuruan languages. Kaufman has suggested a relationship with the Chiquitano language, which Nikulin considers to be a sister of Macro-Jê. Furthermore, Nikulin has suggested that Bororoan has a relationship with the Cariban and Kariri languages:
An automated computational analysis by Müller et al. also found lexical similarities between Bororoan and Cariban.
Language contact
Jolkesky notes that there are lexical similarities with the Guato, Karib, Kayuvava, Nambikwara, and Tupi language families due to contact.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. Similarly, Cariban borrowings are also present in the Karajá languages. Karajá speakers had also adopted ceramic technology from Cariban speakers.
Similarities with Cayuvava are due to the expansion of Bororoan speakers into the Chiquitania region.
