Case mismatching in Icel'ic clausal ellipsis

In this article, we take a detailed look at clausal ellipsis in Icel'ic, a hitherto understudied phenomenon. We focus on case-matching ' case-mismatching facts in fragment responses. We argue that although case matching is the norm, constrained instances of case mismatching strongly suggest that there must be silent structure in the ellipsis site, ' some syntactic identity condition. We outline these patterns in detail, ' provide an analysis that assumes a post-syntactic approach to case marking, ' a hybrid identity condition along the lines of Chung (2013).
