Despite a vast literature on Yiddish relative clauses, their linguistic and geographical aspects have often been neglected. Based on data from the Language and Culture Atlas of Ashkenazic Jewry (JCAAJ), the areal distribution of subject and oblique relative clauses is analyzed for the first time. I show that vos ‘that; what’, which also introduces non-relative complement clauses, is the most common element to introduce subject relative clauses, whereas in oblique relative clauses, the pronoun velx- ‘which’ predominates. This contrast suggests a division of labor between nonpronominal and pronominal elements depending on the syntactic role of the relativized NP. As to the areal aspect, vos accompanied by a resumptive personal pronoun is primarily used in Central Eastern and Southeastern Yiddish, whereas nonrelative comple-mentizing vos is typical of Southeastern and central Northeastern Yiddish. These areal distributions mirror patterns of coterritorial Slavic languages: The more widespread use of nonrelative complementizing vos is reminiscent of the corresponding use of Ukrainian ščo and Belarusian što ‘what; that’, whereas the preference for resumptive personal pronouns is observed in Polish and Ukrainian. Comparatively recent convergence with Slavic seems to play a role in the emergence of resumptive pronouns and nonrelative complementizing vos in the varieties of Yiddish.*

尽管有大量关于意第绪语关系从句的文献，但它们的语言和地理方面经常被忽视。基于德系犹太人语言文化地图集（JCAAJ）的数据，首次分析了主从句和斜相对从句的区域分布。我展示了vos 'that; what' 也引入了非关系补语从句，是引入主语关系从句的最常见元素，而在斜关系从句中，代词velx - 'which' 占主导地位。这种对比表明非代词和代词元素之间的分工取决于相对化 NP 的句法作用。至于面积方面，vos伴随着恢复人称代词主要用于中东部和东南意第绪语，而非相对补语vos是典型的东南和中东北意第绪语。这些区域分布反映了同属斯拉夫语言的模式：非相对补充vos的更广泛使用让人想起乌克兰语ščo和白俄罗斯语što 'what; 那'，而在波兰语和乌克兰语中观察到对恢复人称代词的偏好。最近与斯拉夫语的融合似乎在意第绪语变体中恢复代词和非相对补充vos的出现中发挥了作用。 *
