The effort of the editors of this volume is highly commendable. The editors not only made a careful and insightful selection of relevant papers for this volume, but also ensured that the papers met the goals of the volume. Indeed, the papers are able to put into clear perspective the notion of phrase and the importance of heads, edges, and projections on interface legibility conditions that underlie development in linguistic minimalism. These ideas allow for a systematic parameterization of phasal heads cross-linguistically. [ ...] This volume is a useful resource for linguists and cognitive scientists who are interested in advances in minimalism and situating language within or outside human cognitive systems. Although the volume presupposes familiarity with the basics of linguistic minimalism, as espoused in Chomsky (1995), and more recently in Chomsky (2008), among others, it is also meant for interested members of the public with a more than casual interest in developments in theoretical linguistics, particularly, in minimalist linguistics. -- Lengji Nudiya Danjuma, University of Jos, on Linguist List 23.5104, 2012
