Ancient Belgian language

Ancient Belgian is a hypothetical extinct Indo-European or Pre-Indo-European language, spoken in Belgica (northern Gaul) in late prehistory with no known written records. It is mostly explained by Celtic onomastics, but having some features distinct from neighbouring languages, including Germanic. It is sometimes identified with the hypothetical Nordwestblock. 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.
