'In Language and Complex Systems, William Kretzschmar brings complexity theory to linguistics. Clear and compelling, the book offers a fresh perspective on the way that orderliness arises in language.' Edwin Battistella, Southern Oregon University 'This book is the most powerful account of linguistic variation I have seen. It will change the way all kinds of linguists - from socio to generative - perceive language.' Dr Laura Wright, University of Cambridge 'Even for readers familiar with The Linguistics of Speech and Kretzschmar's other work, Language and Complex Systems is an important synthesis and will be worth reading and thinking about again and again.' Edwin Battistella, Language and Dialogue
