Yes, those are all the countries on the continent of South America that start with C and P.

The origin of each country's name:
* Columbia: Derived from the last name of the Italian navigator Christopher Columbus.
* Chile: Possibly either derived from the Picunche tribal chief called *Tili*, after a town and valley named Chili in the Casma Valley in Peru, or from a Native American word meaning either 'ends of the earth' or 'sea gulls.'
* Peru: Possibly derived from *Birú*, the name of a local ruler who lived near the Bay of San Miguel, Panama City, in the early 16th century.
* Paraguay: Either comes from the Guarani as a combination of the words *para*, meaning river, and *guay*, meaning this side or from the Guarani word *paraguá*, which means feather crown.
