Chimila language
Chimila is a Chibchan language of Colombia, spoken by the Chimila. At one time the Malibu languages were grouped with Chimila, before Chimila was considered a Chibchan language.
The "Cesar" name of the Cesar River and Cesar Department is an adaptation from the Chimila indigenous word Chet-tzar or Zazare into Spanish, in reference to the Cesar River.
Guatapurí derives from the Chimila for "cold water", and provides the name of the Guatapurí River.
