Discourse markers constitute an important part of linguistic communication, and research on this phenomenon has been a thriving field of study over the past three decades. However, a problem that has plagued this research is that these markers exhibit a number of structural characteristics that are hard to interpret based on existing methodologies, such as grammaticalization. This study argues that it is possible to explain such characteristics in a meaningful way. It presents a cross-linguistic survey of the development of discourse markers, their important role in communication, and their relation to the wider context of sociocultural behaviour, with the goal of explaining their similarities and differences across a typologically wide range of languages. By giving a clear definition of discourse markers, it aims to provide a guide for future research, making it essential reading for students and researchers in linguistics, and anyone interested in exploring this fascinating linguistic phenomenon.

Extensively revised and updated, this second edition provides, in an A-Z format, an analysis of the most important generalizations that have been made on the unidirectional change of grammatical forms and constructions. Based on the analysis of more than 1,000 languages, it reconstructs over 500 processes of grammatical change in the languages of the world, including East Asian languages such as Chinese, Korean and Japanese. Readers are provided with the tools to discover how lexical and grammatical meanings can be related to one another in a principled way, how such issues as polysemy, heterosemy, and transcategoriality are dealt with, and why certain linguistic forms have simultaneous lexical and grammatical functions. Definitions of lexical concepts are provided with examples from a broad variety of languages, and references to key relevant research literature. Linguists and other scholars will gain a better understanding of languages on a worldwide scale.
