This paper examines whether the selection of linking elements for novel German compounds can be better explained in terms of a single or a dual-route model. Previous studies had focused on the predictability of linking elements by rules. We investigate a single-route model by focusing on the paradigmatic analogical effect of the compounds sharing the left (right) constituent with the target compound, i.e., the left (right) constituent family. A production experiment reveals an effect of the left, but not of the right constituent family. Simulation studies of the responses, using a computational model of paradigmatic analogy, show that the left constituent and its phonological and morphological properties (rime, gender, and inflectional class) simultaneously codetermine the selection of linking elements. We show how these results can be accounted for by a single-route approach, and we outline a symbolic interactive activation model that merges the factors into one psycholinguistically motivated processing mechanism.
