One known river is the Danube.
The name Danube is applied from the confluence of the two source rivers Brigach and Breg near Donaueschingen in the Black Forest. The source of the Danube is sometimes considered to be a spring in the castle of Donaueschingen. However, this is a quibble and the real source of the Danube is the source of the Breg (which is longer than the Brigach, but both of them rise in the Black Forest in Germany).
The Danube river is in Europe and runs through Germany and several other nations. It is not in North America.
It can be Hungarian or Middle-Eastern. It depends how you pronounce it.

The name Danube is derived from the Latin word "Danubius." The Danube originates in Germany and flows through different countries until it empties into the Black Sea.
