Discourse particles, discourse markers and pragmatic markers refer to phenomena that linguists have begun to probe only since the mid-1980s. Long-ignored in traditional linguistics and textbook grammars, and still relegated to marginal status in South Slavic, these linguistic phenomena have emerged as invaluable devices for cutting-edge theories of the semantics/pragmatics interface. This book, which is a pioneering study in such linguistic phenomena in South Slavic languages, is also among the first of its kind for a related group of languages. It builds on the recent findings of some of the most influential linguistically-oriented theories, such as Relevance Theory, Argumentation Theory and coherence-based approaches to explain the meaning and use of certain discourse/pragmatic particles/markers in Bulgarian, Macedonian, Serbian, Bosnian, Croatian and Slovene. These particles/markers are part of the contemporary and historical lexicons of the South Slavic languages, varying across regions and time, but also differing in origin.
