Babar is a fictional elephant, featuring in stories by Jean de Brunhoff and later his son. The name "Babar" is similar to baba, a word originally meaning "father" but used as an honorific in many Asian countries, and also similar to Babur, a Mughal emperor whose name is sometimes transliterated as Babar (apparently the predominance of the name Babur is to avoid confusion with the elephant!), but both of these are names originating in Asia while evidence points (mostly) to Babar being an African elephant. Slightly less similar to "Babar" is the word Berber, used for an ethnic group in parts of Africa that were colonised by France, who prefer to be known as Amazigh people.
What is the origin of Babar's name? Is there any word from the author on how he came up with the name, or evidence from the books or historical/cultural context on what likely inspired it?
