This collection of papers fills a gap in current research on both metapragmatics and pragmatics in that it combines data-based pragmatic analysis with metapragmatic theory and focuses on the ways in which metadiscourse is actually used. The 12 contributions investigate speech acts and verbal (as well as non-verbal) expressions which highlight (meta-)linguistic aspects of ongoing discourse and thus provoke a deviation from the latter’s original direction and purpose. All case studies discuss ways and means which interactants employ to resolve diverging pragmatic expectations in communication. The papers analyze authentic examples from English and other languages (and cultures), including Thai, Chinese and Japanese, and center around three principal domains of communication: ordinary everyday interaction, interaction in educational contexts and in specialized discourse. The introductory chapter locates the various contributions within a systematically broader theoretical framework. The wide scope of the collection, its empirical orientation and the reader-friendly form of presentation should appeal to anyone interested in pragmatics, whether scholar or student.
