Abstract
In this paper, we investigate the factors that influence interactants’ choice of syntactic variants when using a predicative adjective construction like that is okay. In German colloquial conversation, such constructions can occur as full sentences with subject, copula and adjective (das ist gut ‘that is good’); with topic drop consisting of copula and adjective (ist gut); or as fragments consisting only of the adjective (gut). We present findings from a corpus of colloquial speech between fellow students showing that the interactional function of listener feedback has a higher predictive power in accounting for the use of fragments vs. fuller structures than adjective semantics (descriptive vs. evaluative), propositional structure (reference to individual or propositionally structured referent), and predictability in terms of adjective frequency. Moreover, we find that fragments consisting of evaluative adjectives show a clear tendency to be grounded in the here-and-now of the current situation, whereas fuller structures are more apt to express evaluations grounded in past experience. We argue that fragments are formally optimized to convey expressive actions such as listener feedback and other ad-hoc evaluations.
