Functional approaches to the study of language may not only be used to characterize discourse structures, but also to assess their communicative quality. In fact, discourse analysis and evaluation are conceptually related activities. In this volume the link between analysis and evaluation is explored in seven studies discussing a variety of discourse genres like package inserts, telephone openings, survey interviews, meetings, government brochures and direct mail letters. The analytical concepts used stem from different strands of research into language, including cognitive linguistics, pragmalinguistics, conversational analysis and persuasion research.
