In this pioneering study, a world-renowned generative syntactician explores the impact of phenomena known as 'third factors' on syntactic change. Generative syntax has in recent times incorporated third factors – factors not specific to the language faculty – into its framework, including minimal search, labelling, determinacy and economy. Van Gelderen's study applies these principles to language change, arguing that change is a cyclical process, and that third factor principles must combine with linguistic information to fully account for the cyclical development of 'optimal' language structures. Third Factor Principles also account for language variation around that-trace phenomena, CP-deletion, and the presence of expletives and Verb-second. By linking insights from recent theoretical advances in generative syntax to phenomena from language variation and change, this book provides a unique perspective, making it essential reading for academic researchers and students in syntactic theory and historical linguistics.

The papers in this collection share a common interest in the empirical, theoretical and meta-theoretical aspects of the ‘internal-external’ (‘formal-functional’) debate in linguistic theory. The primary aim of this volume is to initiate cooperation between internationally renowned generative and variationist linguists with a view to developing an innovative and more cohesive approach to syntactic variation. The present volume contains treatments incorporating the analysis of external factors into accounts focusing on the internal linguistic conditioning of syntactic variation and change cross-linguistically. As such, it offers novel approaches to three key areas of current linguistic debate, viz. (1) Methodological practices, (2) Theoretical applications and (3) Modularity. The volume is, therefore, an important achievement for the progress of linguistic theory more generally and it is an even more crucial milestone in the coming-of-age of ‘Socio-Syntax’ as a discipline in its own right.

This book applies recent theoretical insights to trace the development of Castilian and Latin American Spanish from the Middle Ages onwards, through processes of repeated dialect mixing both within the Iberian Peninsula and in the New World. The author contends that it was this frequent mixing which caused Castilian to evolve more rapidly than other varieties of Hispano-Romance, and which rendered Spanish particularly subject to levelling of its linguistic irregularities and to simplification of its structures. These two processes continued as the language extended into and across the Americas. These processes are viewed in the context of the Hispano-Romance dialect continuum, which includes Galician, Portuguese and Catalan, as well as New World varieties. The book emphasises the subtlety and seamlessness of language variation, both geographical and social, and the impossibility of defining strict boundaries between varieties. Its conclusions will be relevant both to Hispanists and to historical sociolinguists more generally.

This volume brings together the latest diachronic research on syntactic features and their role in restricting syntactic change. The chapters address a central theoretical issue in diachronic syntax: whether syntactic variation can always be attributed to differences in the features of items in the lexicon, as the Borer-Chomsky conjecture proposes. In answering this question, all the chapters develop analyses of syntactic change couched within a formalist framework in which rich hierarchical structures and abstract features of various kinds play an important role. The first three parts of the volume explore the different domains of the clause, namely the C-domain, the T-domain and the ?P/VP-domain respectively, while chapters in the final part are concerned with establishing methodology in diachronic syntax and modelling linguistic correspondences. The contributors draw on extensive data from a large number of languages and dialects, including several that have received little attention in the literature on diachronic syntax, such as Romeyka, a Greek variety spoken in Turkey, and Middle Low German, previously spoken in northern Germany. Other languages are explored from a fresh theoretical perspective, including Hungarian, Icelandic, and Austronesian languages. The volume sheds light not only on specific syntactic changes from a cross-linguistic perspective but also on broader issues in language change and linguistic theory.

The study of language variation in social context continues to hold the attention of a large number of linguists. This research is promoted by the annual colloquia on New Ways of Analyzing Variation in English' (NWAVE). This volume is a selection of revised papers from the NWAVE XI, held at Georgetown University. It deals with a number of items, some of which have often been discussed, others that have been less emphasized. The first group of articles in the volume center on a frequent theme: speech communities as the essential setting for understanding variation in language. Earlier work in linguistic variation dealt for the most part with phonological variation and change. Syntactic and morphological change and variation in syntax are also discussed. A selection on the role of variation in understanding first language acquisition comprises three papers. Articles in the last section of the volume concern theoretical controversy and methodological advances.
