Word order change in German infinitival complementation

The present article discusses whether processing factors might play a role in the reduction of word order variability in German infinitival complements of control verbs, connecting evidence from a diachronic corpus study to processing considerations and psycholinguistic findings. We show that intraposition, a linearization pattern that has been claimed to be costly in comprehension due to both center-embedding and temporary ambiguity, became less frequent in language use over time. Findings from language production experiments show that present-day German speakers avoid producing intraposition patterns even following repeated exposure to this pattern. Taken together, our findings are consistent with the hypothesis that processing factors can influence the distribution of word order variants. Looking at the diachronic dimension, however, reveals that the effect of processing factors can be modulated by sociolinguistic factors and the impact of language modality.
