Witotoan languages

Witotoan is a small language family of southeastern Colombia and the neighbouring region of Peru.

Genetic relations

Aschmann proposed that the Boran and Witotoan language families were related, in a Bora–Witoto stock. Echeverri & Seifart refute the connection.

Jolkesky notes that there are lexical similarities with the Pijao, Yaruro, Arawak, Bora-Muinane, Choko, and Tukano language families due to contact. Some of this contact had occurred due to the expansion of Witotoan speakers down the Putumayo River.
