“Exonym” is a neologism (newly coined word) that was first used by Australian geographer Marcel Aurousseau in his 1957 book, “The Rendering of Geographical Names.” It comes from the Greek “exō,” meaning “outside,” and “-onym,” a Greek noun-forming suffix. The United Nations Group of Experts on Geographical Names defines an exonym as a “name used in a specific language for a geographical feature situated outside the area where that language is spoken, and differing in its form from the name used in an official or well-established language of that area where the geographical feature is located.” It defines its opposite, “endonym,” as a “name of a geographical feature in an official or well-established language occurring in that area where the feature is located.” For instance, “Germany” is the English-language exonym for “Deutschland,” which is the endonym Germans use.
