In 2011, the annual conference series Going Romance celebrated its 25th edition in Utrecht, the founder city of the enterprise. Since its inception in the eighties of the last century, the local initiative has developed into the major European discussion forum for research focussing on the contribution of (one of the) Romance languages to general linguistic theorizing as well as on the working out of in-depth analyses of Romance data within linguistic frameworks. The annual meeting took place on December, 8-10.The present volume is the 5th of the series Romance Languages and Linguistic Theory published by John Benjamins. We publish here a selected set of peer-reviewed articles bearing on topics in phonology, morphology, syntax and semantics, that represent both issues of theoretical nature as well as developments in the field of acquisition. The articles are of great interest for specialists of Romance and for general linguists appreciating parameters and/or language acquisition. Among the contributions are three papers presented by invited speakers (Andrea Calabrese, Ricardo Etxepare and Jason Rothman), while two other very prominent Romance linguists figure as co-authors (Aafke Hulk, Luigi Rizzi).
