This paper analyzes the properties of the Present Perfect in Barranquenho/Barranqueno, a contact variety spoken in the southern border of Portugal and Spain. In this variety, the Present Perfect displays a mixed structure: while the forms of auxiliary and participle are from Portuguese, its range of interpretations is not attested in Portuguese but rather in Spanish. As in other domains of the grammar of Barranquenho that have been studied, the Present Perfect displays features attributable to Portuguese and to Spanish. These findings are discussed against hypotheses regarding the emergence of this contact variety as well as the theoretical debate concerning the relation between language contact and second language acquisition.

目前的完美边界：语言接触研究

本文分析了Barranquenho / Barranqueno（目前在葡萄牙和西班牙南部边界使用的一种接触品种）中“现在完美”的特性。在这个品种中，“现在完成”显示了一个混合的结构：虽然助词和分词的形式来自葡萄牙语，但其解释范围不是用葡萄牙语证明的，而是用西班牙语证明的。就像在巴兰奎尼奥语法的其他领域一样，《现代完美》展现了归因于葡萄牙语和西班牙语的特征。这些发现是针对有关这种接触形式出现的假设以及有关语言接触与第二语言习得之间关系的理论辩论进行讨论的。
