What does viscacha mean?
Viscacha is a specialized English zoological noun for a South American burrowing rodent in the chinchilla family. The name is used especially for the plains viscacha and mountain viscacha, both members of the genus Lagostomus. Found in arid and mountainous parts of Argentina, Bolivia, Chile, and Peru, these animals live in social groups and excavate extensive underground burrows. They should not be confused with chinchillas: viscachas are larger, more robust terrestrial burrowers, whereas chinchillas are smaller rodents commonly associated with rocky slopes. In ordinary English, viscacha is uncommon; it appears mainly in zoological writing, natural-history accounts, and descriptions of South American wildlife. The word reached English through the Spanish vizcacha, which is generally traced to the Quechua wiskacha. Its usefulness lies in identifying a distinctive group of rodents and distinguishing them from similarly named or closely related animals. The regular English plural is viscachas.
