The semantic status of discourse markers

In this paper, I propose a definition of discourse markers, incorporating a discussion of their status within linguistics in general, and more specifically their semantic status. With respect to the latter, I consider at some length what type of semantic theory is needed to account for the meanings and functions of markers. Subsequently, I give a brief overview of some of the more important previous research on markers, and I end by presenting an equally brief exemplary analysis of one specific French discourse marker, namely bon.
