Relations between Arawakan and Guaicuruan groups in the Chaco region of South America have been widely discussed in ethnohistorical and anthropological sources. This paper offers the first systematic investigation of the linguistic effects of these interactions, relying on, and contributing to, the historical study of both language families. I discuss a number of nominal lexemes in Terena, the extant descendant of Guana, that lack plausible Arawakan etymologies, thus being candidates for items adopted from some non-Arawakan language. I show that the Terena items in question are loans from Northern Guaicuruan languages and can be traced to source forms with established Guaicuruan etymologies. I propose some linguistic markers that characterize the Guaicuruan stratum in the Terena lexicon, particularly well-represented in the domains of zoonyms and phytonyms. Consequences of these findings are discussed, including their relation to the independent claims of the ethnohistorical literature.

南美查科的阿拉瓦坎-瓜伊库鲁语语言联系

南美洲查科地区的阿拉瓦坎族和怪古族族群之间的关系在民族历史和人类学资料中得到了广泛的讨论。本文对这些互动的语言影响进行了首次系统调查，依赖于并促进了对这两个语系的历史研究。我讨论了 Terena（Guana 的现存后裔）中的一些名义词素，它们缺乏合理的 Arawakan 词源，因此是从一些非 Arawakan 语言中采用的项目的候选词。我表明，所讨论的 Terena 项目是从北 Guaicuruan 语言中借来的，并且可以追溯到具有已建立的 Guaicuruan 词源的源形式。我提出了一些表征 Terena 词典中的 Guaicuruan 阶层的​​语言标记，在动物群和植物群领域中表现尤为突出。讨论了这些发现的后果，包括它们与民族历史文献的独立主张的关系。
