Revisiting German two-way prepositions

Abstract German two-way prepositions have long troubled grammar writing. Unlike most other German prepositions, they occur with both accusative and dative case. Their case is difficult to predict and has been attributed to different underlying meaning construals. Recent exploratory corpus studies propose that, in addition, their case depends on multiple co-occurring contextual variables. Following this approach, this study uses multivariate regression and collostructional analysis to investigate what determines the case of two-way prepositions in a large sample of authentic language use. Based on the results, this study then attempts to provide a usage-based description of the case of two-way prepositions. Contrary to expectations, none of the proposed variables had much influence on case, suggesting that the effects observed in the literature only hold for specific contexts. Instead, the results indicated associations of accusative and dative with individual prepositions and specific lexical items in the context. Framed in terms of usage-based construction grammar, this is interpreted as item-specific constructional prototypes that emerge from typical usage patterns and, once established, determine case based on form-meaning overlap with the current context of use. In line with recent usage-based research on grammar, a first attempt is made to describe case as part of a network of associative links between constructions and lexical items.
