'This attractive textbook is a great opportunity to bring the unique historical and typological richness of the Romance languages to today's students of language and linguistics and empower them to continue its exploration on their own. In its carefully gradated approach at complex issues of phonology and morphology, the authors provide readers with an analytical in-depth investigation of the diachronic developments in Spanish, French, and Italian, complemented by coherent sketches of Portuguese and Romanian. The book sets a new standard for focus, relevance, and accuracy of data as well as broadly informed and open-minded assessment of competing explanations offered in the literature. Readers who work their way through the book will come away from it with a structured picture of this fascinating language family spanning 2000 years of varying divergence and convergence.'
