Recent years have seen intense debates between formal (generative) and functional linguists, particularly with respect to the relation between grammar and usage. This debate is directly relevant to diachronic linguistics, where one and the same phenomenon of language change can be explained from various theoretical perspectives. In this, a close look at the divergent and/or convergent evolution of a richly documented language family such as Romance promises to be useful. The basic problem for any approach to language change is what Eugenio Coseriu has termed the paradox of change: if synchronically, languages can be viewed as perfectly running systems, then there is no reason why they should change in the first place. And yet, as everyone knows, languages are changing constantly. In nine case studies, a number of renowned scholars of Romance linguistics address the explanation of grammatical change either within a broadly generative or a functional framework.

This book advances research on grammatical change and shows the breadth and liveliness of the field. International scholars report on the nature and outcomes of all aspects of syntactic change, including grammaticalization, variation, syntactic movement, determiner-phrase syntax, pronominal systems, case systems, negation, and alignment.

The newly-emerging field of theoretically informed but simultaneously empirically based syntax is dynamic but little-represented in the literature. This volume addresses this need. While there has previously been something of a gulf between theoretical linguists in the generative tradition and those linguists who work with quantitative data types, this gap is narrowing. In the light of the empirical revolution in the study of syntax, even people whose primary concern is grammatical theory take note of processing effects and attribute certain effects to them. Correspondingly, workers focusing on the surface evidence can relate more to the concepts of the theoreticians, because the two layers of explanation have been brought into contact. And these workers too must account for the data gathered by the theoreticians. An additional innovation is the generative analysis of historical data – this is now seen as psycholinguistic theory-relevant data like any other. These papers are thus a snapshot of some of the work currently being done in evidence-based grammar, using both experimental and historical data.

This book contains 15 revised papers originally presented at a symposium at Rosendal, Norway, under the aegis of The Centre for Advanced Study (CAS) at the Norwegian Academy of Science and Letters. The overall theme of the volume is ‘internal factors in grammatical change.’ The papers focus on fundamental questions in theoretically-based historical linguistics from a broad perspective. Several of the papers relate to grammaticalization in different ways, but are generally critical of ‘Grammaticalization Theory’. Further papers focus on the causes of syntactic change, pinpointing both extra-syntactic (exogenous) causes and – more controversially – internally driven (endogenous) causes. The volume is rounded up by contributions on morphological change ‘by itself.’ A wide range of languages is covered, including Tsova-Tush (Nakh-Dagestan), Zoque, and Athapaskan languages, in addition to Indo-European languages, both the more familiar ones and some less well-studied varieties.

Under which circumstances does grammatical change come about? Is the child the principle agent of change as suggested by historical linguistics?This book discusses diachronic change of languages in terms of restructuring of speakers' internal grammatical knowledge. Efforts to construct a theory of diachronic change consistent with findings from psycholinguistics are scarce. Here, these questions are therefore addressed against the background of insights from research on monolingual and bilingual acquisition. Given that children are remarkably successful in reconstructing the grammars of their ambient languages, commonly held views need to be reconsidered according to which language change is primarily triggered by structural ambiguity in the input and in settings of language contact. In an innovative take on this matter, the authors argue that morphosyntactic change in core areas of grammar, especially where parameters of Universal Grammar are concerned, typically happens in settings involving second language acquisition. The children acting as agents of restructuring are either L2 learners themselves or are continuously exposed to the speech of L2 speakers of their target languages. Based on a variety of case studies, this discussion sheds new light on phenomena of change which have occupied historical linguists since the 19th century and will be welcomed by advanced undergraduate and graduate students as well as researchers in the fields of historical linguistics and language acquisition.

The volume surveys over a hundred diachronic changes from typologically diverse languages and concludes that the definitional property of meaning change in grammaticalization is that it never results in a decrease in the semantic or pragmatic scope of the construction.

This volume focuses on different aspects of language development. The contributions are concerned with similarities and differences between first and second language acquisition, the acquisition of sentence structure and functional categories, cross-linguistic influence in bilingual first language acquisition as well as the relation between language acquisition, language contact and diachronic change. The recurrent topic of the volume is the link between linguistic variation and the limitation of structural variability in the framework of a well-defined theory of language. In this respect, the volume opens up new perspectives for future research.

Different components of grammar interact in non-trivial ways. It has been under debate what the actual range of interaction is and how we can most appropriately represent this in grammatical theory. The volume provides a general overview of various topics in the linguistics of Romance languages by examining them through the interaction of grammatical components and functions as a state-of-the-art report, but at the same time as a manual of Romance languages.
