Abstract:

The preservation of length in the West Slavic and South-West Slavic genitive-locative dual in *-ū is unexpected and to date unexplained. BCS rùkū 'handsGEN.PL' is likely to continue a trisyllabic preform. At the same time, Indo-Iranian and Greek offer strong evidence for PIE o-stem and ā-stem archetypes that should have yielded late Proto-Slavic and OCS *-oju (thus, OCS *rǫkoju), rather than *-u. The actually attested OCS form is rǫku. The present study seeks to provide a unified account of these two problems. The development of some of the PIE dual endings in other daughter traditions, including Greek and its dialects, is also addressed.

摘要：

*- ū中西斯拉夫语和西南斯拉夫语属格-位置二元对长度的保留是出乎意料的，迄今为止无法解释。BCS rùkū 'hands GEN.PL ' 很可能延续三音节预制。同时，印度-伊朗语和希腊语为 PIE o -stem 和ā -stem 原型提供了强有力的证据，它们应该产生晚期原始斯拉夫语和 OCS *- oju（因此，OCS * rǫkoju），而不是 *- u。实际证明的 OCS 形式是rǫku. 本研究旨在对这两个问题进行统一说明。其他子传统（包括希腊语及其方言）中某些 PIE 双重结尾的发展也得到了解决。
