The Andean countries are a group of South American nations that are located in the western part of the continent. Chile (5 letters), Peru (4 letters), Colombia (3 letters), and Ecuador (5 letters) are all part of this region. The animals native to the Andes, such as llamas (5 letters) and alpacas (6 letters), are also associated with the region. The INCA (4 letters) civilization was one of the most powerful empires in the region, and their legacy is still seen today in the form of ruins and artifacts. The OCA (3 letters) and ocas (4 letters) are traditional Andean crops that are still grown in the region today.
