This article investigates a peculiar pattern of subject case-marking in the Greek of southern Italy. Recent fieldwork with native speakers, coupled with the consultation of some written sources, reveals that, alongside prototypical nominative subjects, Italo-Greek also licenses accusative subjects, despite displaying a predominantly nominative-accusative alignment. Far from being random replacements within a highly attrited grammar, the distribution of these accusative subjects obeys specific structural principles, revealing similarities with historical attestations of the so-called “extended accusative” in early Indo-European. On the basis of these data, Italo-Greek is argued to be undergoing a progressive shift towards an active-stative alignment, a claim supported by additional evidence from auxiliary selection, adverb agreement and sentential word order.

本文调查了意大利南部希腊语中一种特殊的主语格标记模式。最近对以母语为母语的人进行的实地调查以及对一些书面资料的咨询表明，除了典型的主格主语外，意大利语-希腊语还许可宾格主语，尽管它显示出主要的主格-宾格对齐。这些宾格主语的分布并非在高度磨损的语法中随机替换，而是遵循特定的结构原则，揭示了与早期印欧语中所谓“扩展宾格”的历史证明的相似之处。在这些数据的基础上，意大利-希腊语被认为正在逐步转向主动-静态对齐，这一说法得到了辅助选择的额外证据的支持，
