This paper provides a description of the Accusative case in Tundra Yukaghir. Contrary to the previous analyses, I argue that Tundra Yukaghir has a syntactic Accusative case that is realised by two dedicated morphological forms, the distribution of which depends on a complex network of lexical specifications, the semantics of the NP and its structural properties. The description of the Accusative serves as a background for the discussion of two difficult questions of case theory. First, I show that Differential Argument Marking in Tundra Yukaghir cannot be reduced to one or more overarching syntactic or semantic features, as is commonly done in the literature, but is rather triggered by an idiosyncratic mixture of factors and is thus rather a matter of listing than of syntactic derivation. Second, I apply the method of mapping morphological properties of case on syntactic features and use recurring patterns to identify those features that are relevant for the definition of a syntactic case in Tundra Yukaghir. The method can be applied in various languages to help solve the difficult issue of identifying case.

句法案例：Tundra Yukaghir中的宾格

本文提供了对Tundra Yukaghir中控罪案件的描述。与先前的分析相反，我认为Tundra Yukaghir具有句法宾格，它由两种专用的形态形式实现，其形态取决于词汇规范，NP语义及其结构特性的复杂网络。宾格的描述是讨论案例理论两个难题的背景。首先，我证明在Tundra Yukaghir中的差异自变量标记不能像文献中那样简化为一个或多个总体句法或语义特征，而是由各种特有的因素触发的，因此仅是列表问题而不是句法推导。第二，我应用了在句法特征上映射案例的形态特性的方法，并使用重复模式来识别与Tundra Yukaghir中的句法案例的定义相关的那些特征。该方法可以以多种语言来应用，以帮助解决识别案件的难题。
