Concord describes a natural language phenomenon in which a single logical meaning is expressed syntactically on multiple lexical items. The canonical example is negative concord, in which multiple negative expressions are used, but a single negation is interpreted. Formally similar phenomena have been observed for the redundant marking of distributivity and definiteness. Inspired by recent dynamic analyses of these latter two phenomena, we extend a similar dynamic analysis to negative concord. We propose that negative concord items introduce a discourse referent (like an existential), but then test that no discourse referent has been introduced in any assignment. These apparently contradictory requirements are licensed with split scope around negation: introduction occurs below negation; the test appears above it. The analysis successfully predicts that negative concord items must be licensed by a sufficiently local negative operator. We further show that modulation of what is at-issue can account for cases in which NC items themselves carry negative force.

和睦描述了一种自然语言现象，其中在多个词汇项上句法表达了单个逻辑含义。典范的例子是否定一致，其中使用了多个否定表达式，但只解释了一个否定。对于分布性和确定性的冗余标记，已经观察到形式上相似的现象。受最近对后两种现象的动态分析的启发，我们将类似的动态分析扩展到了负面和谐。我们提议否定和解项引入话语指称（如存在），然后测试是否在任何作业中都没有引入话语指称。这些明显矛盾的要求在否定的范围内得到了许可：引入在否定之下进行；测试将显示在其上方。分析成功地预测了负一致项目必须由足够本地的负运算符许可。我们进一步表明，对问题的调制可以解释其中NC项目本身携带负力的情况。
