Child-directed speech (CDS) is an important but under-documented genre within the Indigenous languages of the Americas, and recent work has argued that the documentation of CDS can also provide valuable material for linguistic description. This article analyzes more than 25 hours of video-recorded CDS in Iiyiyiuyimuwin (Northern East Cree) to enrich and expand the analysis of the morphosyntax of obviation, a characteristic feature of Algonquian languages. The article elucidates under-described properties of demonstratives, particularly in possessive constructions, to show the crucial roles that obviative demonstratives can play in disambiguating syntax and marking grammatical information not encoded by co-occurring nouns and verbs. Additionally, it explores some morphosyntactic conditions behind under-described variation in obviative forms within the expansive demonstrative paradigm. The usage of particular obviative variants seems tied not to grammatical features such as distance, animacy, or number but instead to whether demonstratives serve pronominal, adnominal, or equational functions.

克里语东北部的明显指示：来自面向儿童的演讲的见解

面向儿童的演讲 (CDS) 是美洲土著语言中一种重要但文献记载不足的体裁，最近的研究表明，CDS 的文献也可以为语言描述提供有价值的材料。本文分析了 Iiyiyiuyimuwin (Northern East Cree) 超过 25 小时的视频录制 CDS，以丰富和扩展对 Algonquian 语言的特征性特征 obviation 的形态句法的分析。这篇文章阐明了指示词的描述不足的属性，特别是在所有格结构中，以显示明显指示词在消除语法歧义和标记非同现名词和动词编码的语法信息方面可以发挥的关键作用。此外，它探讨了扩展示范范式中明显形式的以下描述的变化背后的一些形态句法条件。特定明显变体的使用似乎与距离、活力或数字等语法特征无关，而是与指示词是否服务于代词、名词或等式功能有关。
