This new edition of TUFS Studies in Linguistics, we aim to showcase the various linguistics research conducted at Tokyo University of Foreign Studies. In this first volume, we report on the international symposium hosted by the Global Center of Excellence Program "Corpus-based Linguistics and Language Education (CbLLE)" throughout 2008.

As its title suggests, this book is a selection of papers that use English corpora to study language variation along three dimensions – time, place and genre. In broad terms, the book aims to bridge the gap between corpus linguistics and sociolinguistics and to increase our knowledge of the characteristics of English language. It includes eleven papers which address a variety of research questions but with the commonality of a corpus-based methodology. Some of the contributions deal with language variation in time, either by looking into historical corpora of English or by adopting the method known as diachronic comparable corpus linguistics, thus illustrating how corpora can be used to illuminate either historical or recent developments of English. Other studies investigate variation in space by comparing different varieties of English, including some of the “New Englishes” such as the South Asian varieties of English. Finally, some of the papers deal with variation in genre, by looking into the use of language for specific purposes through the inspection of medical articles, social reports and academic writing.

Using Corpora to Explore Linguistic Variation illustrates the ways in which linguistic variation can be explored through corpus-based investigation. Two major kinds of research questions are considered: variation in the use of a particular linguistic feature, and variation across dialects or registers. Part 1: “Exploring variation in the use of linguistic features” focuses on the study of specific words, expressions, or grammatical constructions, to study variation in the use of a particular linguistic feature. Part 2: “Exploring dialect and register variation” describes salient characteristics of dialects or registers and the patterns of variation across varieties. Part 3: “Exploring Historical Variation” applies these same two major perspectives to historical variation. One recurring theme is the extent to which linguistic variation depends on register differences, reflecting the importance of register as a key methodological and thematic concern in current corpus linguistic research.

Many large-scale investigations of linguistic variation are unfeasible using traditional approaches. This volume is a collection of papers that illustrate the ways in which linguistic variation can be explored through corpus-based investigation.

This volume provides a comprehensive overview of the research carried out over the past thirty years in the vast field of legal discourse. The focus is on how such research has been influenced and shaped by developments in corpus linguistics and register analysis, and by the emergence from the mid 1990s of historical pragmatics as a branch of pragmatics concerned with the scrutiny of historical texts in their context of writing. The five chapters in Part I (together with the introductory chapter) offer a wide spectrum of the latest approaches to the synchronic analysis of cross-genre and cross-linguistic variation in legal discourse. Part II addresses diachronic variation, illustrating how a diversity of methods, such as multi-dimensional analysis, move analysis, collocation analysis, and Darwinian models of language evolution can uncover new understandings of diachronic linguistic phenomena.

Variability is characteristic of any living language. This volume approaches the ‘life cycle’ of linguistic variability in English using data sources that range from electronic corpora to the internet. In the spirit of the 1968 Weinreich, Labov and Herzog classic, the fifteen contributions divide into three sections, each highlighting different stages in the dynamics of English across time and space. They show, first, how increase in variability can be initiated by processes that give rise to new patterns of discourse, which can ultimately crystallize into new grammatical elements. The next phase is the spread of linguistic features and patterns of discourse, both new and well established, through the social and regional varieties of English. The final phase in this ebb and flow of linguistic variability consists of processes promoting some variable features over others across registers and regional and social varieties, thus resulting in reduced variation and increased linguistic homogeneity.

The present volume includes a selection of 20 papers from the 31st Annual Conference of the International Computer Archive of Modern and Medieval English (ICAME), held in Giessen (Germany) in May 2010. The conference topic was “Corpus linguistics and variation in English”. All the papers included in the present Conference Proceedings capture aspects of variation in language use on the basis of corpus analyses, providing new descriptive insights, and/or new methods of utilising corpora for the description of language variation. Of particular interest are the five plenary papers that are included in the present volume, focusing on corpus-based approaches to variation in language from different disciplinary perspectives: Stefan Th. Gries (quantitative-statistical descriptions of variation and corpora), Michaela Mahlberg (stylistic variation and corpora), Miriam Meyerhoff (variational sociolinguistics and corpora), Edgar W. Schneider (regional variation and corpora) and Elizabeth C. Traugott (historical variation/grammaticalization and corpora).
