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 recurrent processes that operate in language use. The evidence is based on the study of large corpora of spoken and written language, what we know about how languages change, as well as the results of experiments with language users. The result is an integrated theory of language use and language change which has implications for cognitive processing and language evolution.

Exploring the intricate relationship between language experience and phonological representation, this book delves into how individual interactions with language shape auditory perception and speech production. It offers a fresh perspective on phonology by examining the cognitive processes involved in language comprehension and use, emphasizing the significance of speaker and hearer experiences. Through comprehensive analysis, it challenges traditional views and seeks to redefine the understanding of phonological structures in linguistic theory.

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 cognitive processes and usage factors that are rarely mentioned in other textbooks. Complete with questions for discussion, suggested readings and a useful glossary of terms, this book helps students to gain a general understanding of language as an ever-changing system.
