How do countries get their names?

A few countries have names that describe their people’s attributes: Burkina Faso, coined in 1984, means “land of honest men” or “land of incorruptible people.” Guinea and its namesakes—Guinea-Bissau, Papua New Guinea, Equatorial Guinea—come possibly from the Tuareg word “aginaw,” “black people,” used by the Portuguese in the 15th century to refer to a larger region of west Africa.
