The purpose of this paper is to explore academic linguistics' tacit reliance on a Christian missionary organization, SIL International, to develop technological infrastructure and offer service in local linguistic communities—areas that have generally been ignored by academic linguistics because they have been seen as falling outside its domain of professional responsibility. We refer to these kinds of activities as PRACTICAL LANGUAGE DEVELOPMENT because they draw upon linguistic expertise to solve practical real-world problems. Until now, academic linguists have benefited from the practical language development work carried out by our missionary counterparts without much deliberation. But with the contemporary rise in concern over language endangerment, the time has come for us to reflect on how this partnership of convenience can be reconciled with the changing priorities of the discipline. As we redouble our efforts to document, understand, and support the world's linguistic diversity, academic linguists are taking a renewed interest in fieldwork. There are more numerous and generous sources of funding for endangered-language research. Documentary linguistics, which takes the collection, preservation, and annotation of primary linguistic data as its key aim, is emerging as a subfield in its own right (Woodbury 2003, Himmelmann 2006). A growing recognition of the social and economic forces that drive language shift has led many linguists to see basic research in small, minority, and indigenous language communities as addressing issues of human rights (Nettle & Romaine 2000, Skutnabb-Kangas 2000, Hinton 2002). Moral and political questions like who funds linguistic work, who carries it out, and who benefits from it and how are much harder to ignore in the context of these changes (Dorian 1993, England 1995). At the same time, changes in the way information is communicated, initiated by the spread of digital technology, have created demands for precise methods of referring to language names, written characters, lexical items, and other linguistic objects. But movements within the academy have not kept pace with these demands.
