Pano-Tacanan languages
Pano-Tacanan (also Pano-Takana, Pano-Takánan, Pano-Tacana, Páno-Takána) is a proposed family of languages spoken in Peru, western Brazil, Bolivia and northern Paraguay. There are two close-knit branches, Panoan and Tacanan (Adelaar & Muysken 2004; Kaufman 1990, 1994), with 33 languages. There are lexical and grammatical similarities between the two branches, but it has not yet been demonstrated that these are genetic (Loos 1999). Most Panoan languages are spoken in either Peru or western Brazil; a few are in Bolivia. All Tacanan languages are spoken in Bolivia (Ese’ejja is also spoken in Peru). Genealogical  relations. Migliazza has presented lexical evidence in support of a genetic relationship between the Panoan and Yanomaman languages. He also suggests that a Panoan–Chibchan relationship is plausible. Jolkesky (2016) also notes that there are lexical similarities with the Arawakan languages due to contact. Comparison.
