Joan Bybee and her colleagues present a new theory of the evolution of grammar that links structure and meaning in a way that directly challenges most contemporary versions of generative grammar. This study focuses on the use and meaning of grammatical markers of tense, aspect, and modality and identifies a universal set of grammatical categories. The authors demonstrate that the semantic content of these categories evolves gradually and that this process of evolution is strikingly similar across unrelated languages.

Referencing new developments in cognitive and functional linguistics, phonetics, and connectionist modeling, this book investigates various ways in which a speaker/hearer's experience with language affects the representation of phonology. Rather than assuming phonological representations in terms of phonemes, Joan Bybee adopts an exemplar model, in which specific tokens of use are stored and categorized phonetically with reference to variables in the context. This model allows an account of phonetically gradual sound change that produces lexical variation, and provides an explanatory account...

Language demonstrates structure while also showing considerable variation at all levels: languages differ from one another while still being shaped by the same principles; utterances within a language differ from one another while exhibiting the same structural patterns; languages change over time, but in fairly regular ways. This book focuses on the dynamic processes that create languages and give them their structure and variance. It outlines a theory of language that addresses the nature of grammar, taking into account its variance and gradience, and seeks explanation in terms of the...

How and why do languages change? This new introduction offers a guide to the types of change at all levels of linguistic structure, as well as the mechanisms behind each type. Based on data from a variety of methods and a huge array of language families, it examines general patterns of change, bringing together recent findings on sound change, analogical change, grammaticalization, the creation and change of constructions, as well as lexical change. Emphasizing crosslinguistic patterns and going well beyond traditional methods in historical linguistics, this book sees change as grounded in...
