The status of agreement is a core issue in current morphological and syntactic theory. The collection of papers in this volume focuses on important issues, such as the nature of the relation between syntax and morphology in determining agreement relations; whether and which syntactic configurations are relevant for determining agreement; the relevance of verbal agreement for the purposes of EPP; the inquiry into the existence of connections between verbal and DP-internal agreement; on the morphological and syntactic distinction of person, number and gender agreement; how and why AGREE and Spec,head relations trigger different agreement effects; and the type of relation that exists between head-movement and morphological agreement. The data collected come from a wide variety of languages and the studies presented discuss innovative and thought-provoking ideas for dealing with agreement phenomena.
