This collection of chapters reinforces the importance of the Romance languages as an area of investigation that can provide new empirical data while advancing linguistic theory. The chapters cover a range of languages, theoretical issues, and methodological advances. Several chapters that flesh out the syntactic Left Periphery using the relatively recent cartographic approach are complemented by corpus based studies that use substantial data to investigate theoretical issues. Despite the particular focus of each chapter, they also intersect in important ways. What makes this volume unique is that by approaching current theoretical topics from vastly different perspectives, the chapters inform our understanding of language in general. Altogether, these chapters both shed light on particular syntax and particular languages, and build our general understanding of the Left Periphery, its functional projections, features and syntax-semantics interface.
