Contact phenomena in the verbal complex: the Walser connection in the Alpine area

In the context of the Alps – a broad region characterized by common geographical and cultural features – the isolation caused by the geographical setting makes it possible for conservative strategies to survive from the Middle Ages through present times. This isolation, however, does not exclude that conservative patterns evolve into innovative strategies. To illustrate this, we surveyed causative and progressive constructions in the historical German minority varieties on the southern side of the Alps. Greschòneytitsch, a particularly dynamic variety, shows the remarkable development of a causative particle, tònz, and the grammaticalization of an adverb, eister, into a marker of progressive aspect.
