This book brings together a series of contributions to the study of grammaticalization of tense, aspect, and modality from a functional perspective. All contributions share the aim to uncover the functional motivations behind the processes of grammaticalization under discussion, but they do so from different points of view.

This textbook introduces and explains the fundamental issues, major research questions, and current approaches in the study of grammaticalization - the development of new grammatical forms from lexical items, and of further grammatical functions from existing grammatical forms. Grammaticalization has been a vibrant research field in recent years, and has proven effective in explaining a wide range of phenomena; it has even been claimed that the only true language universals are diachronic, and are related to cross-linguistic processes of grammaticalization. The chapters provide a detailed account of the major issues in the field: foundational questions such as directionality, criteria and parameters of grammaticalization, and phases and cycles; the much-debated issue of the motivations behind grammaticalization, including the role of language contact and typological influences; the advantages and disadvantages of different theoretical approaches; and the relationship between grammaticalization and process such as lexicalization, exaptation, and the development of discourse markers. Each chapter offers guidance on further reading, and concludes with study questions to encourage further discussion; there is also a glossary of key terminology in the field. Thanks to its comprehensive approach, the volume will serve as both a textbook for undergraduate and graduate students and a valuable reference work for researchers in the field.

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.

This book is a cross-linguistic exploration of semantic and functional change in modal markers. Its approach is broadly functional typological but makes frequent reference to work in formal semantics by scholars such as Angelika Kratzer and Paul Portner. The author starts by considering what modality is and how it relates to and differs from subjectivity. He argues that modality cannot be defined in terms of subjectivity: both concepts are independent of each other, the first exhibiting different degrees of subjectivity, and the second being operative in a much wider range of grammatical and lexical categories. Subjectivity, he suggests, should not be defined solely in terms of performativity, evidentiality, or construal, but rather from the interplay of multiple semantic and pragmatic factors. He then presents a two-dimensional model for the descriptive representation of modality, based on the notion that among the many aspects of modal meaning, volitivity and speech-act-orientation versus event-orientation are two of its most salient parameters. He shows that it is especially the dimension of speech-act orientation versus event-orientation, parallel to category climbing in syntax, that is operative in diachronic change. Numerous examples of diachronic change within modality and between modality and other categories are then examined with respect to their directionality. With a focus on Japanese and to a lesser extent Chinese the book is a countercheck to hypotheses built on the Indo-European languages. It also contains numerous illustrations from other languages.

This book presents the state of the art in research on grammaticalization, the process by which lexical items acquire grammatical function, grammatical items get additional functions, and grammars are created. Leading scholars from around the world introduce and discuss the core theoretical and methodological bases of grammaticalization, report on work in the field, and point to promising directions for new research. They represent every relevant theoretical perspective and approach.
Research on grammaticalization and its role in linguistic change encompasses work on languages from every major linguistic family. Its results offer valuable insights for all theoretical frameworks, including generative, construction, and cognitive grammar, and relates to work in fields such as phonology, sociolinguistics, and language acquisition. The handbook provides a full, critical assessment of every aspect of this research. It is divided into five parts, of which the first two are devoted to theory and method, the third and fourth to work in linguistic domains, classes, and cateogories, and the fifth to case studies of grammaticalization in a range of languages. It will be an indispensable source of information and inspiration for all those who wish to know more about this fascinating and important field.
