The name Muiname has been used to refer to the Muinane language (Bora Muinane) of the Boran family and also to the Nipode language (Witoto Muinane) of the Huitotoan family.
The names Koto, Coto, and Orejón have been used to refer to the Koihoma language (Coixoma) and also to the unrelated Orejón language (also known as Koto or Coto) of the Tucanoan language family.
Aschmann (1993) proposed that the Boran and Witotoan language families were related, in a Bora–Witoto stock. Echeverri & Seifart (2016) refute the connection.
