Vom Matrixsatz zum Diskursmaker: Die Grammatikalisierung von Hauptsache

Abstract

<p>This paper has a double purpose. On the one hand, it intends to prove the existence of a discourse marker (DM) Hauptsache. This element preserves the core conceptual meaning of the homonymous noun, but differs from it with regard to its morphosyntactic and semantic features as well as to its discourse-organizing, information structuring, and modal functions. On the other hand, the emergence of Hauptsache as a discourse particle is explained on the grounds of a grammaticalization process similar to the ones described for the prototypical German DMs. Evidence drawn from a corpus of German and Austrian parliamentary protocols will show in which ways the six fundamental processes implied in the grammaticalization of DMs (decategorization, scope expansion, subjectification, persistence, syntactic fixation, phonetic and/or morphosyntactic reduction) can be found in the evolution from the matrix clause die Hauptsache is to the monolexematic Hauptsache. The paper ends with a brief discussion of the formal, semantical, and functional characteristics of Hauptsache.</p>
