TRENDS IN LINGUISTICS is a series of books that open new perspectives in our understanding of language. The series publishes state-of-the-art work on core areas of linguistics across theoretical frameworks as well as studies that provide new insights by building bridges to neighbouring fields such as neuroscience and cognitive science. TRENDS IN LINGUISTICS considers itself a forum for cutting-edge research based on solid empirical data on language in its various manifestations, including sign languages. It regards linguistic variation in its synchronic and diachronic dimensions as well as in its social contexts as important sources of insight for a better understanding of the design of linguistic systems and the ecology and evolution of language. TRENDS IN LINGUISTICS publishes monographs and outstanding dissertations as well as edited volumes, which provide the opportunity to address controversial topics from different empirical and theoretical viewpoints. High quality standards are ensured through anonymous reviewing.

This specially commissioned volume considers the processes involved in language change and the issues of how they can be modelled and studied. The way languages change offers an insight into the nature of language itself, its internal organisation, and how it is acquired and used. Accordingly, the phenomenon of language change has been approached from a variety of perspectives by linguists of many different orientations. This book, originally published in 2003, brings together an international team of leading figures from different areas of linguistics to re-examine some of the central issues in this field and also to discuss new proposals. The volume is arranged into sections, including grammaticalisation, the typological perspective, the social context of language change and contact-based explanations. It seeks to cover the subject as a whole, bearing in mind its relevance for the general analysis of language, and will appeal to a broad international readership.

In Grammaticalising the Perfect and Explanations of Language Change: Have- and Be-Perfects in the History and Structure of English and Bulgarian, Bozhil Hristov investigates key aspects of the verbal systems of two distantly related Indo-European languages, highlighting similarities as well as crucial differences between them and seeking a unified approach. The book reassesses some long-held notions and functionalist assumptions and shines the spotlight on certain areas that have received less attention, such as the role of ambiguity in actual usage. The detailed analysis of rich, contextualised material from a selection of texts dovetails with large-scale corpus studies, complementing their findings and enhancing our understanding of the phenomena. This monograph thus presents a happy marriage of traditional philological techniques and recent advances in theoretical linguistics and corpus work.

This volume provides an up-to-date discussion of a foundational issue that has recently taken centre stage in linguistic typology and which is relevant to the language sciences more generally: To what extent can cross-linguistic generalizations, i.e. statistical universals of linguistic structure, be explained by the diachronic sources of these structures? Everyone agrees that typological distributions are the result of complex histories, as “languages evolve into the variation states to which synchronic universals pertain” (Hawkins 1988). However, an increasingly popular line of argumentation holds that many, perhaps most, typological regularities are long-term reflections of their diachronic sources, rather than being ‘target-driven’ by overarching functional-adaptive motivations. On this view, recurrent pathways of reanalysis and grammaticalization can lead to uniform synchronic results, obviating the need to postulate global forces like ambiguity avoidance, processing efficiency or iconicity, especially if there is no evidence for such motivations in the genesis of the respective constructions. On the other hand, the recent typological literature is equally ripe with talk of "complex adaptive systems", "attractor states" and "cross-linguistic convergence". One may wonder, therefore, how much room is left for traditional functional-adaptive forces and how exactly they influence the diachronic trajectories that shape universal distributions. The papers in the present volume are intended to provide an accessible introduction to this debate. Covering theoretical, methodological and empirical facets of the issue at hand, they represent current ways of thinking about the role of diachronic sources in explaining grammatical universals, articulated by seasoned and budding linguists alike.

This volume presents the outcome of a workshop, held in Amsterdam in 1985, on the nature, even possibility, of explanation in Historical Linguistics: why changes take place and others do not, and why they occur at a particular time and place. The workshop, and this volume, aim to explore questions such as i) are the factors which explain the actuation of a change different from those that explain its implementation?; ii) is it possible to give a typology of changes?; iii) should linguistic explanation hope to meet the same requirements as explanation in the pure sciences?; iv) are all linguistic changes necessarily the product of variation?; v) should there be a formal theory of change apart from a general thoery of grammar?

Roger Lass offers a critical survey of the foundations of the art of historical linguistics.

Thomas Berg challenges context-free theories of linguistics; he is concerned with the way the term 'explanation' is typically used in the discipline. He argues that real explanations cannot emerge from a view which asserts the autonomy of language, but only from an approach which seeks to establish a connection between language and the contexts in which it is embedded. The author examines the psychological context in detail. He uses an interactiveactivation model of language processing to derive predictions about synchronic linguistic patterns, the course of linguistic change, and the structure of poetic rhymes. The majority of these predictions are borne out, leading the author to conclude that the structure of language is shaped by the properties of the mechanism which puts it to use, and that psycholinguistics thus qualifies as one likely approach from which to derive an explanation of linguistic structure.
