Processing Factors Constrain Word-Order Variation in German: The Trouble with Third Constructions

A subset of German control verbs allows for the discontinuous linearization of their infinitival complements, a word-order pattern known as the “third construction” pattern. Compared to alternative word-order options (notably, extraposition), third constructions are very rare in present-day German. Here we ask whether the third construction pattern’s low occurrence frequency can be accounted for by processing factors. We report the results from a self-paced reading task and a production priming task investigating whether third constructions are difficult to comprehend, difficult to produce, or both. Our results show that the third construction pattern’s local structural ambiguity impedes comprehension, and that the pattern is also resistant to priming. We conclude that this word-order pattern is an example of a “latent” construction that is grammatically licensed but strongly dispreferred in language use because easier-to-process word-order variants are available.
