When data consist of grouped observations or clusters, and there is a risk that measurements within the same group are not independent, group-specific random effects can be added to a regression model in order to account for such within-group associations. Regression models that contain such group-specific random effects are called mixed-effects regression models, or simply mixed models. Mixed models are a versatile tool that can handle both balanced and unbalanced datasets and that can also be applied when several layers of grouping are present in the data; these layers can either be nested or crossed. In linguistics, as in many other fields, the use of mixed models has gained ground rapidly over the last decade. This methodological evolution enables us to build more sophisticated and arguably more realistic models, but, due to its technical complexity, also introduces new challenges. This volume brings together a number of promising new evolutions in the use of mixed models in linguistics, but also addresses a number of common complications, misunderstandings, and pitfalls. Topics that are covered include the use of huge datasets, dealing with non-linear relations, issues of cross-validation, and issues of model selection and complex random structures. The volume features examples from various subfields in linguistics. The book also provides R code for a wide range of analyses.

Cognitive Sociolinguistics is a novel and burgeoning field of research which seeks to foster investigation into the socio-cognitive dimensions of language at a usage-based level. Advances in Cognitive Sociolinguistics brings together ten studies into the social and conceptual aspects of language-internal variation. All ten contributions rely on a firm empirical basis in the form of advanced corpus-based techniques, experimental methods and survey-based research, or a combination of these. The search for methods that may adequately unravel the complex and multivariate dimensions intervening in the interplay between conceptual meaning and variationist factors is thus another characteristic of the volume. In terms of its descriptive scope, the volume covers three main areas: lexical and lexical-semantic variation, constructional variation, and research on lectal attitudes and acquisition. It thus illustrates how Cognitive Sociolinguistics studies both the variation of meaning, and the meaning of variation.

Cognitive Linguistics has given a major impetus to the study of semantics and the lexicon. The present volume brings together seventeen previously published papers that testify to the fruitfulness of Cognitive Linguistics for the study of lexical and semantic topics. Spanning the period from the late 1980s to recent years, the collection features a number of papers that may be considered classics within the field of cognitive linguistic lexicology. The papers are grouped in thematic sections. The first section deals with prototypicality as a theoretical and practical model of semantic description. The second section discusses polysemy and criteria for distinguishing between meanings. The third section tackles questions of meaning description beyond the level of words, on the level of idioms and constructions. The following section casts the net even wider, dealing with the cultural aspects of meaning. Moving away from the theoretical and descriptive perspective towards applied concerns, the fifth section looks at lexicography from the point of view of Cognitive Linguistics. The final section has a metatheoretical orientation: it discusses the history and methodology of lexical semantics. Each paper is preceded by a newly written introduction that situates the text against the period in which it was first published, but that also points to further developments, in the author's own research or in Cognitive Linguistics at large. The variety of topics dealt with make this book an excellent introduction to the broad field of lexicological and lexical semantic research.

The significant advances witnessed over the last years in the broad field of linguistic variation testify to a growing convergence between sociolinguistic approaches and the somewhat older historical and comparative research traditions. Particularly within cognitive and functional linguistics, the evolution towards a maximally dynamic approach to language goes hand in hand with a renewed interest in corpus research and quantitative methods of analysis. Many researchers feel that only in this way one can do justice to the complex interaction of forces and factors involved in linguistic variability, both synchronically and diachronically. The contributions to the present volume illustrate the ongoing evolution of the field. By bringing together a series of analyses that rely on extensive corpuses to shed light on sociolinguistic, historical, and comparative forms of variation, the volume highlights the interaction between these subfields. Most of the contributions go back to talks presented at the meeting of the Societas Linguistica Europaea held in Leuven in 2001. The volume starts with a global typological view on the sociolinguistic landscape of Europe offered by Peter Auer. It is followed by a methodological proposal for measuring phonetic similarity between dialects designed by Paul Heggarty, April McMahon, and Robert McMahon. Various papers deal with specific phenomena of socially and conceptually driven variation within a single language. For Dutch, Jose Tummers, Dirk Speelman, and Dirk Geeraerts analyze inflectional variation in Belgian and Netherlandic Dutch, Reinhild Vandekerckhove focuses on interdialectal convergence between West-Flemish urban dialects, and Arjan van Leuvensteijn studies competing forms of address in the 17th century Dutch standard variety. The cultural and conceptual dimension is also present in the diachronic lexicosemantic explorations presented by Heli Tissari, Clara Molina, and Caroline Gevaert for English expressions referring to the experiential domains of love, sorrow and anger, respectively: the history of words is systematically linked up with the images they convey and the evolving conceptualizations they reveal. The papers by Heide Wegener and by Marcin Kilarski and Grzegorz Krynicki constitute a plea against arbitrariness of alternations at the level of nominal morphology: dealing with marked plural forms in German, and with gender assignment to English loanwords in the Scandinavian languages, respectively, their distributional accounts bring into the picture a variety of motivating factors. The four cross-linguistic studies that close the volume focus on the differing ways in which even closely related languages exploit parallel morphosyntactic patterns. They share the same methodological concern for combining rigorous parametrization and quantification with conceptual and discourse-functional explanations. While Griet Beheydt and Katleen Van den Steen confront the use of formally defined competing constructions in two Germanic and two Romance languages, respectively, Torsten Leuschner as well as Gisela Harras and Kirsten Proost analyze how a particular speaker's attitude is expressed differently in various Germanic languages.

Theories of Lexical Semantics offers a comprehensive overview of the major traditions of word meaning research in linguistics. In spite of the growing importance of the lexicon in linguistic theory, no overview of the main theoretical trends in lexical semantics is currently available. This book fills that gap by charting the evolution of the discipline from the mid nineteenth century to the present day. It presents the main ideas, the landmark publications, and the dominant figures of five traditions: historical-philological semantics, structuralist semantics, generativist semantics, neostructuralist semantics, and cognitive semantics. The theoretical and methodological relationship between the approaches is a major point of attention throughout the text: going well beyond a mere chronological enumeration, the book does not only describe the theoretical currents of lexical semantics, but also the undercurrents that have shaped its evolution.

Diachronic Prototype Semantics is concerned with the theory of explanation of changes in word meaning. The author demonstrates the explanatory value of the prototype model of meaning, in which the distinction between central and peripheral senses of a word is crucial.
