This book deals with the oft-neglected tensions between perspicuity and vagueness in specialized communication. The volume is distinguished by its coverage of a range of LSP and related specializations, and its sensitivity to both the philosophy of science and practical considerations. It describes indeterminacy phenomena as seen from the standpoint of theoretical, anthropological and cognitive linguistics, safety-critical translating, history and theory of terminology studies, development of ontologies, soft ware localization, jurisprudence and interoperability of digital knowledge representation resources. With contributions by leading scholars drawn from eleven countries, this book benchmarks current LSP scholarship in indeterminacy. [Based on publisher information]
