Sino-Tibetan Etymological Dictionary and Thesaurus (STEDT)

汉藏语，包括汉语和藏缅语（TB），是世界上最大的语系之一，有超过十亿的使用者。然而，人们对它们仍然知之甚少；事实上，结核病家族的一些分支实际上仍未被研究。为了填补历史语言学研究的空白，1987年开始了汉藏语词源词典和辞典项目，负责从现存的出版作品和不断增长的田野调查中收集数据，并将它们整合成一个连贯的整体。该项目的最终目标是出版一本关于祖先语言的词源学词典，即大约6000年前使用的原始汉藏语。该词典是按语义字段组织的，因此它将构成一个PST的“同义词库”。一个包含词源学和词典学信息的大型计算机数据库已经创建，以支持出版词典所需的研究。在这一点上，词汇文件中约有70,000个语素（约20%）已被词源化成同源集。第一卷第一册（身体部位术语）已获准出版。后续分册和卷的编写工作同时进行。在新的赠款期间，将为结核病科的各个亚组编写一系列按语音学组织的历史/比较手册，从卢缅语开始。这将允许严格制定合理的法律和完善我们的“合理法律数据库”，未来的重建可能会被测试。以这种方式，STEDT项目将沿着语义和语音线进行。为了及时向语言界提供获取数据和结果的途径，该项目将转向通过CD-ROM和万维网出版。随着词典本身的分册，其他STEDT出版物的电子版本将很快提供，包括STEDT专著系列的出版卷和我们的半年度期刊藏缅语言学的后刊。

The Sino-Tibetan languages, comprising Chinese and Tibeto-Burman (TB), constitute one of the great language families of the world, with well over a billion speakers. Yet they remain poorly understood; indeed, some branches of the TB family are still virtually unstudied. To fill this vacuum in historical linguistic research, the STEDT (Sino-Tibetan Etymological Dictionary and Thesaurus) project was started in 1987, charged with gathering data from both extant published works and the growing body of fieldwork and integrating them into a coherent whole. The ultimate goal of the project is the publication of an etymological dictionary of the ancestor language, Proto-Sino-Tibetan, spoken perhaps 6000 years ago. The Dictionary is organized by semantic fields, so it will constitute a 'thesaurus' of PST.A large computer database of etymological and lexicographic information has been created to support the research required to publish the Dictionary. At this point about 70,000 morphemes in the lexical file (ca. 20%) have been etymologized into cognate sets. The first Fascicle of Vol. I (Body-part Terminology) has been approved for publication. Preparation of the subsequent Fascicles and Volumes is proceeding concurrently.In the new grant period, a series of phonologically organized Historical/Comparative Handbooks will be prepared for the various subgroups of the TB family, beginning with Lolo-Burmese. This will allow the rigorous formulation of sound-laws and the refinement of our 'Sound-law Data-base', against which future reconstructions may be tested. In this manner the STEDT project will proceed both along semantic and phonological lines. In order to provide the linguistic community with access to data and results in a timely fashion, the project will move towards publication via CD-ROM and the WWW. Along with the fascicles of the Dictionary itself, electronic versions of other STEDT publications will quickly be made available, including published volumes of the STEDT Monograph Series and back issues of our semiannual journal Linguistics of the Tibeto-Burman Area.
