Language-contact phenomena in Mesoamerica and adjacent regions present an exciting field for research that has the potential to significantly contribute to our understanding of language contact and the role that it plays in language change. This volume presents and analyzes fresh empirical data from living and/or extinct Mesoamerican languages (from the Mayan, Uto-Aztecan, Totonac-Tepehuan and Otomanguean groups), neighboring non-Mesoamerican languages (Apachean, Arawakan, Andean languages), as well as Spanish. Language-contact effects in these diverse languages and language groups are typically analyzed by different subfields of linguistics that do not necessarily interact with one another. It is hoped that this volume, which contains works from different scholarly traditions that represent a variety of approaches to the study of language contact, will contribute to the lessening of this compartmentalization.
