Ancient 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 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.
