This book offers an original account of the dynamics of syntactic change and the evolving structure of Old Spanish that combines rigorous manuscript-based investigation, quantitative analysis and a syntactic approach grounded in Minimalist thinking. Its analysis of both successful and failed changes demonstrates the degree of unpredictability caused by the interaction of competing factors and will shed fresh light on the assumed unidirectionality of linguistic change. Importantly, it reveals that Old Spanish and modern Spanish are more similar to one another than is usually supposed and demonstrates that many of the differences between the two varieties are quantitative rather than qualitative. This theoretically sophisticated examination of historical corpora will provide an invaluable resource for students and scholars of Old and modern Spanish, historical linguistics, sociolinguistics and syntax.Ian E. Mackenzie is Professor of Spanish Linguistics at Newcastle University, UK. He is the author of seven books, as well as numerous articles in the fields of syntax, semantics and diachronic linguistics.

“In his latest book, Ian E. Mackenzie marries grammatical theory and quantitative methods to make significant advances in the analysis of a range of syntactic phenomena in Old Spanish. Alongside meticulous corpus-based empirical work, he critically engages with recent concepts in the theory of quantitative historical linguistics to great effect. This book is highly recommended to anyone interested in the history of the Spanish language and indeed in language change more broadly.” (Richard Waltereit, Professor of Romance Linguistics, Humboldt University Berlin, Germany)

Provides data-informed models that describe the evolution of Old Spanish syntax and enable broader conclusions to be drawn on the nature of language change Deconstructs and critically examines the term ‘Old Spanish’, placing it within its proper historical context Applies a combination of quantitative data mining and theoretical analysis to a large component of the medieval prose corpus Addresses the intriguing question of ‘failed change’ in language evolution
