Dictionaries of endangered languages represent especially important products of language documentation, in part because they are usually the most familiar and useful genre of linguistic representation to endangered language community members. This familiarity, however, can become problematic when it is accompanied by language ideologies that equate dictionaries with word lists ("words for things"), prescriptive linguistics, and researchers' neoliberal assumptions regarding the circulation of knowledge. Recent and ongoing research in the Village of Tewa (N. Arizona, Kiowa-Tanoan language family) designed to produce a practical dictionary in support of the community's language renewal efforts provides some examples of the need to contextualize the project within the community and to understand the pervasive role of language ideologies when working collaboratively. This research project aims to promote and fortify lexical documentation so that the practical dictionary is an adequate guide for future community members, while still conforming to cultural protocols about lexical representation and circulation, both within and outside the language community.
