Language
As the Collas are a multiethnic people, they had no single indigenous language but spoke a blend of Aymara, Kunza and even the Kakán of the Diaguita groups inhabiting the Calchaquíes valleys in Argentina; but their mode of speaking was lost over the years. Today, the Collas who inhabit the mountains of Copiapó and Chañaral speak Spanish, although their speech is interspersed with Quecha terms that are kept alive by the elders and by repetition in traditional ceremonies and songs.
