The aim of this paper is to examine contact-induced changes, visible on lexical and lexico-syntactical levels, in the set of twenty sixteenth-century petitions in Nahuatl from the region of Santiago de Guatemala. They comprise such phenomena as the creation and usage of neologisms, extentions of meaning, the adoption of loans in the morphological system of Nahuatl and the usage of calques. The material is divided in three parts. The first one focuses on specific traits of the Nahuatl language in which the Guatemalan petitions were composed, taking into account an ongoing discussion among researchers concerning the identification of this language or languages. The second part focuses on the presentation of selected lexical and lexico-syntactic changes in Nahuatl due to the influence of the Spanish language, as compared with similar contact-induced phenomena from Central Mexico and attested within the same time span. In the last part of the paper the interdependence of language contact and culture contact is discussed within the perspective of a presumed conceptual equivalency and interchangeability of the Spanish and Nahuatl terms for deer and horse, which appears in one of the studied documents.

本文的目的是研究在危地马拉圣地亚哥地区纳瓦特尔的二十世纪二十个请愿书中，在词汇和词汇-句法层面上可见的接触引起的变化。它们包括诸如新词的创建和使用，意义的扩展，纳瓦特尔形态学体系中借用的借用以及轻便的用法等现象。该材料分为三个部分。第一个着重于危地马拉请愿书所组成的纳瓦特尔语的特定特征，同时考虑到研究人员之间关于该一种或多种语言的识别的持续讨论。第二部分重点介绍由于西班牙语的影响而在Nahuatl中选择的词汇和词汇句法变化，与来自墨西哥中部的类似的接触诱发现象相比，并在同一时间范围内得到了证明。在本文的最后一部分中，在研究的文件之一中，以西班牙和纳瓦特尔人对鹿和马的术语的假定概念对等和互换性的角度讨论了语言接触和文化接触的相互依存关系。
