Etymology

From Ancient Greek χώρα (khṓra, “location”) + πλῆθος (plêthos, “a great number”) + English map. First proposed in 1938 by American geographer John Kirtland Wright to mean "quantity in area," although maps of the type have been used since the early 19th century. See: Ancient Greek Nouns 'χώρα', English Nouns 'map'.
