An unusual new map has been released, called the Atlas of True Names.
It reveals the etymological roots, or original meanings, of the names of countries all over the world.Listen
The map was created by Stephan Hormes.
With so many different meanings and translations for place names, Mr Hormes says he did not intend the map to be a scientific scholarship.
Instead he chose names that he believed were the most likely explanation, as a way of introducing the world of place names to a wider audience.
The BBC's Sunita Nahar asked him what had inspired him to create such a map.
