Coherence with adjectives in German

Abstract

Coherence generally refers to a kind of predicate formation where a verb forms a complex predicate with the head of its infinitival complement. Adjectives taking infinitival complements have also been shown to allow coherence, but the exact conditions for coherence with adjectives appear not to have been addressed in the literature. Based on a corpus-study (supplemented with grammaticality judgements by native speakers) we show that adjectives fall into three semantically and syntactically defined classes correlating with their ability to construct coherently. Non-factive and non-gradable adjectives allow coherence, factive and gradable adjectives do not allow coherence and non-factive and gradable adjectives are tolerated with coherence. On the basis of previous work on coherence in German we argue that coherence allows the infinitival complement of a verb or an adjective to be "split-up", so that the head and a dependent of this head are associated with different information structural functions. In this respect coherence patterns with extraction structures where the extracted constituent has an information structural function different from the constituent from which it is extracted. Following literature on the information structural basis of extraction islands, we show how the lack of coherence with factive adjectives follows from their complements' being information structurally backgrounded, while the infinitival complements of non-factive adjectives tend to a higher fusion with the matrix clause. We also show that coherence is observed with attributive adjectives as well, arguing that coherence is not a distinct verbal property. Finally we provide an analysis of coherence with adjectives within HPSG.
