Idiome und ihre kommunikative Leistung
Idioms and their communicative capacities
Résumé
Abstract The aim of this paper is to analyze the communicative function of idioms and their constituents in the information structure of an utterance. Usually idioms tend to occupy the final position in a sentence, which correlates with their inherent rhematic properties. However, structural transformations such as fronting, passivization and conversion can lead to changes in their communicative status. Among such changes, we single out (a) topicalization or thematization of the fronted sentence constituent, (b) its focusing or emphatic rhematization, (c) focusing of the postponed constituent, or (d) rhematization of the sentence as a whole, etc. In spite of their lexical stability, idioms make use of the possibilities provided by German syntax. This allows them to contribute to the communicative structuring of utterances.
