Over the last few decades, there has been a tremendous increase in the production of descriptive grammars for languages that had previously been poorly described or lacked description altogether. In most cases, these are minority languages, and many of them are endangered. The surge in descriptive projects has been accompanied by demand for advances in the art of grammaticography (see e.g. Ameka, Dench & Evans 2006). In this conference, we want to contribute to the development of grammaticography by bringing together linguists who are engaged in writing grammars of underdescribed and/or endangered languages and who are especially interested in utilizing concepts of linguistic typology in their descriptions. We encourage presentations concentrating on the description of specific grammatical structures, as well as wider discussion of the role of typology in grammar-writing. The presentations may take either a language-specific or a cross-linguistic perspective.
