Expected 2019 in Amazonian Spanish: Language Contact and Evolution. John Benjamins. Stephen Fafulas, editor. Language Documentation and Revitalization as a Feedback Loop Colleen M. Fitzgerald The University of Texas at Arlington Abstract In this chapter, I present an overview of language documentation and revitalization focused on the Amazonian context, drawing from several case studies. Prominent areas where language documentation in the Amazon has played and continues to play a significant role are in the innovative use of collaborative or participatory documentation models (i.e., Yamada, 2011, 2014; Stenzel, 2014). I use the case studies highlighted here to expand upon a model of documentation and revitalization that acts as a feedback loop (Fitzgerald, 2017a; Fitzgerald and Hinson 2013, 2016). The resources produced through documentation, revitalization, training and analysis, especially when archived and accessible, will likely be invaluable resources for Amazonian communities engaged in revitalization, as is the case in North America. 1. Introduction 1 The prominence and urgency of language endangerment came to the attention of the larger community of linguists in a powerful series of articles by Hale et al. (1992). Two of those articles focused on Indigenous language communities in Latin America, one in Guatemala (England, 1992) and another in Nicaragua (Craig, 1992), but none are situated in South America, let alone the Amazon. In the quarter century since the publication of these articles, there have been numerous theoretical, technological and ethical developments in linguistics, as well as the development of language documentation, a new subdiscipline. Somewhat parallel to this has been a dramatic increase in the description and analysis of languages in the Amazon. The linguistic structures of its roughly 300 Indigenous languages are of interest for a host of theoretical and 1 This material is based upon work supported by, and conducted while serving at the National Science Foundation, as well as upon work supported by the National Science Foundation under Grants No. BCS-1263699, "Collaborative Research: Documentation and Analysis of the Chickasaw Verb."
