Belgian language

Ancient Belgian is a hypothetical extinct Indo-European language, spoken in Belgica (northern Gaul) in late prehistory. It is often identified with the hypothetical Nordwestblock. While it remains a matter of controversy, the linguist Maurits Gysseling — who himself attributed the term to SJ De Laet — hypothesised a Belgian that was distinct from the later Celtic and Germanic languages. According to the theory, which was further elaborated by Hans Kuhn and others, traces of Belgian can be found in certain toponyms such as South-East-Flemish Bevere, Eine, Mater and Melden.

The borders of the Belgian Sprachraum are made up by the Canche and the Authie in the south-west, the Weser and the Aller in the east, and the Ardennes and the German Mittelgebirge in the south-east. It has been hypothetically associated with the Nordwestblock, more specifically with the Hilversum culture.

The use of the name Belgian for the language is to some extent supported by Caesar's De Bello Gallico which mentions that the Belgae and the Galli spoke different languages. It is furthermore supported by toponyms in present-day Belgium which, according to the linguist Hans Kuhn, point at the existence of an Indo-European language distinct from the Celtic and Germanic languages.
