In languages with aspect-based split ergativity, one portion of the grammar follows an ergative pattern, while another shows a "split." In this book, Jessica Coon argues that aspectual split ergativity does not mark a split in how case is assigned, but rather, a split in sentence structure. Specifically, the contexts in which we find the appearance of a nonergative pattern in an otherwise ergative language involve added structure--a disassociation between the syntactic predicate and the stem carrying the lexical verb stem.

This volume offers theoretical and descriptive perspectives on the issues pertaining to ergativity, a grammatical patterning whereby direct objects are in some way treated like intransitive subjects, to the exclusion of transitive subjects. This pattern differs markedly from nominative/accusative marking whereby transitive and intransitive subjects are treated as one grammatical class, to the exclusion of direct objects. While ergativity is sometimes referred to as a typological characteristic of languages, research on the phenomenon has shown that languages do not fall clearly into one...
