Ergative and accusative behave as dependent cases insofar as their appearance on a nominal depends on the presence of another nominal in the same domain. Recent work on case theory has taken the phenomenon of case dependency to challenge the idea that case is assigned via the operation Agree. Focusing on the Shawi language (Kawapanan; Peru), we show not only that patterns of case dependency can be captured via Agree, but also that doing so opens up a new way of understanding the typology of global case splits. Ergative in Shawi appears when the subject is at least as high as the object on the person hierarchy—a global split pattern—and can be accompanied by explicit realization of the object’s features on the subject nominal (“object agreement on the subject”). We propose that ergative arises in Shawi when a probe on v Agrees with both the object and the subject, transferring object features to the subject; these features are spelled out as ergative case and as object agreement. In general, we show that dependent cases, both ergative and accusative, can be seen as a morphological outcome of syntactic Agree between a probe and a second goal, realizing features on that goal that were transferred from a previous goal in an earlier step of Agree.

同意的从属格：Shawi 中的作格

作格和宾格表现为从属情况，因为它们在名词上的出现取决于同一域中另一个名词的存在。最近关于案例理论的工作采用案例依赖现象来挑战案例通过操作 Agree 分配的想法。重点关注 Shawi 语言（Kawapanan；秘鲁），我们不仅表明可以通过 Agree 捕获案例依赖模式，而且这样做还开辟了一种理解全球案例拆分类型的新方法。当主语在人称层次上至少与客体一样高时（一种全局分裂模式），Shawi 中的作格就出现了，并且可以伴随着主语名义上客体特征的明确实现（“主语上的客体一致性”）。我们认为，当对 v 的探究与宾语和主语都一致时，Shawi 中的作格就会出现，将宾语特征转移给主语；这些特征被阐明为作格和客体一致。一般来说，我们表明，从属情况，无论是作格还是宾格，都可以被视为探针和第二个目标之间句法同意的形态结果，实现该目标的特征，这些特征是在同意的早期步骤中从前一个目标转移的。
