Although usage-based linguistics emphasises the need for studies of language change to take frequency effects into account, there is a lack of research that tries to systematically model frequency effects and their relation to diffusion processes in language change. This monograph offers a diachronic study of the change in Spanish perfect auxiliary selection between Old and Early Modern Spanish that led to the gradual replacement of the auxiliary ser ‘be’ with the auxiliary haber ‘have’. It analyses this process in terms of the interaction between gradience, gradualness, and the conserving effects of frequency and persistence in language change. The study contributes to the theory and methodology of diachronic linguistics, additionally offering insights on how to explain synchronic grammatical variation both within a language and between languages. The book is of interest to the fields of Spanish and Romance linguistics, syntax, as well as historical and variationist linguistics.

The alternation between the auxiliaries BE and HAVE, which this collection examines, is often discussed in connection with generative analyses of split intransitivity. But this book's purpose is to place the phenomenon in a broader context. Well-known facts in the Romance and Germanic language families are extended with data from lesser studied languages and dialects (Romanian, Paduan), and also with experimental and historical data. Moreover, the book goes beyond the usual language families in which the phenomenon has been studied, with the inclusion of two chapters on Chinese and Korean. The theoretical background of the contributors is also broad, ranging from current Generative approaches to Cognitive and Optimality-Theoretical frameworks. Readers interested in the structural, historical, developmental, or experimental aspects of auxiliary selection should profit from this book's comprehensive empirical coverage and from the plurality of contemporary linguistic analyses it contains.

Where is the locus of language variation? In the grammar, outside the grammar or somewhere in between? Taking up the debate between system- and usage-based approaches, this volume provides new discussions of fundamental issues of language variation. It includes several highly insightful theoretical contributions as well as innovative empirical studies considering different types of data, the role of priming in language change and rare phenomena.

A central debate about the description of auxiliary selection concerns the regularity of auxiliary selection from a typological perspective. Thus, studies of auxiliary selection have both stressed the fact that certain recurrent parameters are highly relevant to the description of auxiliary selection, whereas other studies demonstrate significant differences in auxiliary selection systems. By integrating the synchronic and diachronic levels of linguistic description, the papers in the present volume work towards a framework that explains these contradictory findings. They discuss the role of semantic and syntactic constraints in gradient auxiliary selection, address the question of paradigmaticity of the have-be alternation, and shed light on the mechanisms of the gradual historical change from be- to have-selection. The volume thus puts forth a row of innovative theoretical and empirical findings from a wide range of typologically diverse European languages that substantially broaden our knowledge about the mechanisms of auxiliary selection systems.

This is the first book on the acquisition of Spanish that provides a state-of-the-art comprehensive overview of Spanish morphosyntactic development in monolingual and bilingual situations. Its content is organized around key grammatical themes that form the empirical base of research in generative grammar: nominal and verbal inflectional morphology, subject and object pronouns, complex structures involving movement (topicalizations, questions, relative clauses), and aspects of verb meaning that have consequences for syntax. The book argues that Universal Grammar constrains all instances of language acquisition and that there is a fundamental continuity between monolingual, bilingual, child and adult early grammatical systems. While stressing their similarities with respect to linguistic representations and processes, the book also considers important differences between these three acquisition situations with respect to the outcome of acquisition. It is also shown that many linguistic properties of Spanish are acquired earlier than in English and other languages. This book is a must read for those interested in the acquisition of Spanish from different theoretical perspectives as well as those working on the acquisition of other languages in different contexts.

This volume brings together contributions from leading specialists in syntax and morphology to explore the complex relation between periphrasis and inflexion from both a synchronic and diachronic perspective. The chapters draw on data from across the Romance language family, including standard and regional varieties and dialects. The relation between periphrasis and inflexion raises questions for both syntax and morphology, and understanding the phenomena involved requires cooperation across these sub-domains. For example, the components that express many periphrases can be interrupted by other words in a way that is common in syntax but not in morphology, and in some contexts, a periphrastic form may be semantically equivalent to a single-word inflected form, with which it arguably forms part of a paradigmatic set. Patterns of this kind are found across Romance, albeit with significant local differences. Moreover, diachrony is essential in understanding these phenomena, and the rich historical documentation available for Romance allows an in-depth exploration of the changes and variation involved, as different members of the family may instantiate different stages of development. Studying these changes also raises important questions about the relation between attested and reconstructed patterns. Although the empirical focus of the volume is on the Romance languages, the analyses and conclusions presented shed light on the development and nature of similar structures in other language families and provide valuable insights relevant to linguistic theory more broadly.

This text of new work by leading international scholars considers developments in the study of historical linguistics and grammatical theory. It then tests their value and applicability by examining diachronic transmission of syntax at different times and in a wide range of languages
