This monograph aims to contribute to linguistic knowledge about the distribution and function of discourse particles, particularly with respect to a small group of particles which are highly frequent in contemporary spoken standard French. The book is divided into two parts. Part 1 (Theory) defines discourse particles as such, and gives a dynamic global approach to their description. Matters such as previous research on discourse particles, related categories of particles, instructional semantics, the difference between speech and writing, the delimitation of discourse units, competing approaches to discourse structure and to coherence, and methodology are discussed extensively. Part 2 (Description) offers in-depth corpus-based analyses of six French discourse particles, namely BON, BEN, EH BIEN, PUIS, DONC, and ALORS, as used in non-elicted native-speaker interaction.
