This volume explores the progress of cross-linguistic research into the structure of complex nominals since the publication of Chomsky’s ‘Remarks on Nominalization’ in 1970. In the last 50 years of research into the division of labour between the mental lexicon and syntax, the specific properties of nominalized structures have remained a particularly central question. The chapters in this volume take stock of developments in this area and offer new perspectives on a range of issues, including the representation of morphological complexity in the syntax, the correlation of nominal affixes with different types of nominalizations, and the modelling of non-compositional meaning within syntactic approaches to word formation. Crucially, the contributors base their analyses on data from typologically diverse languages, such as Archi, Greek, Hiaki, Icelandic, Mebengokre, Turkish, and Udmurt, and explore the question of whether, cross-linguistically, nominalizations have a uniform core to their structure that can be syntactically described.
