Toponymy

The word "Cayastá" appears for the first time in an ancient document dating from 1607. For the engineer Augusto Fernández Díaz, the etymology of the toponym "Cayastá" derives from the phonetic transformation of "Kollastas" agglutination of "Kolla" and "Astay" that "denotes" moving, from where Cayastá would be "pueblo colla que se muda". Kolla was one of the villages of Aimaraes, with its own dialect, dominated by the Incas.
