This book is a guide for linguistic fieldworkers who wish to write a description of the morphology and syntax of one of the world's many underdocumented languages. It offers readers who work through it one possible outline for a grammatical description, with many questions designed to help them address the key topics; and appendices offer guidance on text and elicited data, and on sample reference grammars which readers might wish to consult. This will be a valuable resource to anyone engaged in linguistic fieldwork.
