A redundant place name is a name that, over time, has become redundant even though most people do not realize it.
At one time, the German "
Tal" was pronounced as (English) "
thal". A valley in Germany was named for Joachim Neander, who wrote many songs.
The valley was the "
Neander-thal" valley which is a redundant place name. The term "
Neanderthal Valley" means the "
Neander valley valley"
Hundreds of years later, bones were discovered in the "
Neander-thal" valley and the people from whom these bones came were named "
Neanderthals".
