Previous studies view the use of Guarani grammatical morphemes in Paraguayan Spanish simply as grammatical borrowings (if one focuses on the morphosyntactic status of mixed forms) or as an ill-defined “interference”. But so far there has been no examination of the bilingual planning mechanisms that license and constrain these language mixes. In this paper, I explore the idea that the emergence of grammatical borrowings can be explained by message conceptualization procedures that are influenced by asymmetries in each language’s cognitive dominance. This work thus contributes to our understanding of language contact by applying what we know about language processing and utterance planning to explaining the outcomes observed in language mixing. In so doing, I hope to facilitate a tighter integration between the psycholinguistic planning and language contact literatures.

以前的研究将巴拉圭西班牙语中瓜拉尼语语法语素的使用视为语法借用（如果关注混合形式的形态句法状态）或定义不明确的“干扰”。但到目前为止，还没有对许可和限制这些语言混合的双语规划机制进行审查。在本文中，我探讨了语法借用的出现可以通过受每种语言认知优势的不对称影响的消息概念化程序来解释的想法。因此，这项工作通过应用我们对语言处理和话语规划的了解来解释语言混合中观察到的结果，从而有助于我们对语言接触的理解。这样做时，
