Introduction: Language contact in the Andes and universal grammar

In this paper we offer a panoramic overview of the development of Andean Spanish and Andean Linguistics, from a theoretical point of view of language contact and universal grammar. We discuss how the notion of Andean Spanish came into existence, the issues under debate, and the consequences of different theoretical positions. We also introduce the contents of the papers included in this special issue, and highlight their key points, framing them in the context of the research on universal grammar. The following five areas are covered: (1) the convergence of Quechua and Aymara, (2) the impact of bilingualism on intonation, (3) the sharing of suffixes in contact situations, (4) the modification of the present perfect tense in Spanish in contact with Quechua, and (5) the properties of the Quechua case system from the point of view of contact varieties. Finally, we provide some remarks on bilingual education, and some suggestions for further directions for future research.
