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

This book is the first major cross-linguistic study of 'flexible words', i.e. words that cannot be classified in terms of the traditional lexical categories Verb, Noun, Adjective or Adverb. Flexible words can - without special morphosyntactic marking - serve in functions for which other languages must employ members of two or more of the four traditional, 'specialised' word classes. Thus, flexible words are underspecified for communicative functions like 'predicating' (verbal function), 'referring' (nominal function) or 'modifying' (a function typically associated with adjectives and e.g. manner adverbs).

This book examines the grammatical changes that took place in the transition from Latin to the Romance languages. The emerging language underwent changes in three fundamental areas involving the noun phrase, verb phrase, and the sentence. The impact of the changes can be seen in the reduction of the Latin case system; the appearance of auxiliary verb structures to mark such categories tense, mood, and voice; and a shift towards greater rigidification of word order. The author considers how far these changes are interrelated and compares their various manifestations and pace of change across the different standard and non-standard varieties of Romance.

The existence of the Welsh-language can come as a surprise to those who assume that English is the foundation language of Britain. However, J. R. R. Tolkien described Welsh as the 'senior language of the men of Britain'. Visitors from outside Wales may be intrigued by the existence of Welsh and will want to find out how a language which has, for at least fifteen hundred years, been the closest neighbour of English, enjoys such vibrancy, bearing in mind that English has obliterated languages thousands of miles from the coasts of England.

This book presents high-quality research of a theoretical and/or empirical/experimental nature, focusing on the interface between language and cognition. This book adopts an interdisciplinary, comparative, multi-methodological approach to the study of language in the general cognitive perspective, as well as theory-based practical applications. It is open to research from the full range of subject disciplines, theoretical backgrounds, and analytical frameworks that inform the language and cognitive sciences.
