Idoburgish

General information
Idoburgish is a Germanic language formerly spoken in an isolated village in western Germany. The name "Idoburg(ish)" doesn't come from the language itself, instead it comes from the contemporary German adaptation of the village's name.

So, the speakers were migrants who were reportedly exiled and travelled to the area west of Aachen, Germany, on the border with the Dutch Limburg. The local languages (namely Limburgish and, to lesser extent, Dutch and Ripuarian) have influenced the language both grammatically and lexically, and several other languages (Old High German, Old Saxon, Old Dutch) contributed only (or mainly) to its vocabulary.
