Page "Cartography" Paragraph 43

Most maps use text to label places and for such things as the map title, legend and other information.

Although maps are often made in one specific language, place names often differ between languages.

So a map made in English may use the name Germany for that country, while a German map would use Deutschland and a French map Allemagne.

A word that describes a place using a non-native terminology or language is referred to as an exonym.
