Language
There is very little information available about the language or languages used by the Chango people. Some authors suggest that they used a blend of the Aymara and Kunza languages, while others claim that they spoke Mapudungun and also understood Kunza. This supports the theory that the Changos were not a single ethnic group but rather a number of largely unrelated tribes.
It has also been suggested that the coastal groups shared a common language that differed from those of the mountain and desert peoples and enabled them to communicate among themselves more easily.
