The term Nederduits, however introduced new confusion, since the non standardised dialects spoken in the north of Germany came to be known as Niederdeutsch as well, and thus the Duits reference in the name was dropped, leading to Nederlands as designation to refer to the Dutch language. The repeated use of Neder (or "low") to refer to the Dutch language is a reference to the Netherlands' downriver location at the Rhine–Meuse–Scheldt delta near the North Sea, harking back to Latin nomenclature, e.g. Germania Inferior.
