Core vs. Periphery in the Charlemagne Sprachbund

In the conclusion to his edited volume in the EUROTYP series on adverbs, Johan van der Auwera (1998b: 824) introduces the term Charlemagne Sprachbund to refer to the area of Western Europe where languages adhere to an array of similar grammatical patterns and thus provide evidence for the existence of a European linguistic area, also called Standard Average European (see Chapter 2 for discussion). Van der Auwera notes that the “core” areas of the Sprachbund are French, German, and Dutch, with Italian and Polish closely linked – all located within or near to the area ruled by Charlemagne. He demonstrates the degree of similarity that exists across European adverbial constructions by assembling a list of the features that tend to occur more frequently in the core area and less frequently in the periphery, counting the occurrence of these features, and grouping the varieties with similar numbers of features on an isopleth map (Figure 7.1) (cf. Haspelmath's similar map, presented as Figure 2.1 in subsection 2.3.1). For reference, we can examine Figure 7.2, which is an actual map of the holdings of Charlemagne at the time of his death in 814.

Van der Auwera (1998: 824) gives the following explanation for this distribution:

He thus points to the essential role of both centrality and peripherality as explanatory principles of innovation through contact, since the profile of groups who did not adopt a change can be as telling as information about those who do.

Van der Auwera goes on to present a similar mapping of temporal-aspectual features of the languages of Europe, based on Thieroff (2000: 265–305), which also points to French and German as core members of the Sprachbund (Figure 7.3).

The features that van der Auwera (1998: 833 n13) utilizes from Theiroff (2000) in order to construct this map are shown in Table 7.1
