Morphological and Abstract Case

This article examines the relationship between abstract and morphological case, arguing that morphological case realizes abstract Case features in a postsyntactic morphology, according to the Elsewhere Condition.Aclass of prima facie ergative-absolutive languages is identified wherein intransitive subjects receive abstract nominative Case and transitive objects receive abstract accusative Case; these are realized through a morphological default, which is often mislabeled as absolutive. Further support comes from split ergativity based on a nominal hierarchy, which is shown to have a morphological source. Proposals that case and agreement are purely morphological phenomena are critiqued.
