This book is a collection of contemporary essays and squibs exploring the mental representation of Spanish and other languages in the Romance family. Although largely formal in orientation, they incorporate experimental and corpus data to inform questions of synchronic and diachronic importance. As a whole, these contributions explore two areas of particular interest to linguistic theorizing. The first is linguistic interfaces with chapters on syntax-information structure, syntax-prosody, syntax-semantics, and lexicon-phonology. The second consists of explorations of noun phrases of all sizes—from clitics to nominalized clauses. The results and conclusions of these studies encourage researchers to continue to explore individual languages in particular in order to gain insight on human language in general. This edited volume in honor of Dr. Paula Kempchinsky is reflective of the diversity of approaches that inspired her teaching, research, and mentoring for over thirty years at the University of Iowa and beyond.
