Harákmbut languages
Harákmbut or Harákmbet is a small language family in Peru spoken by the Harakmbut people.
Campbell notes that Adelaar "presents reasonably persuasive evidence that Harákmbut and Katukinan are genetically related."Jolkesky notes that there are lexical similarities with the Pano, Puinave-Nadahup, Tupian, and Arawakan language families due to contact.
Similarities with Tupian may be indicative of an earlier origin downstream in the Madeira River interaction sphere.
