Sino-Tibetan Etymological Dictionary and Thesaurus (STEDT)

汉藏语系包括汉语和藏缅语，是世界上最大的语系之一，使用者超过10亿。然而，人们对它们的了解仍然很少;事实上，结核病家族的某些分支仍然几乎没有研究。为了填补历史语言学研究的这一空白，1987年开始了《汉藏语词源词典和叙词表》（STEDT）项目，负责从现存的出版著作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大约6000年前使用的原始汉藏语的词源词典。词典按语义场组织，将构成PST的“叙词表”。词典还建立了一个大型的词源和词典信息计算机数据库，以支持出版词典所需的研究工作。在这一点上，词汇文件中大约有70,000个词素（ca。20%）已被词源化为同源集合。 第一卷第一分册（人体部分术语）已批准出版。在新的资助期内，将为TB家族的各个亚组编写一系列按语音组织的历史/比较手册，从Lolo-Burmese开始。 这将允许严格制定健全的法律和完善我们的“健全的法律数据库”，对未来的重建可以进行测试。 这样，STEDT项目将沿着语义和语音路线进行。为了使语言界能够及时获得数据和结果，该项目将逐步通过光盘和万维网出版。沿着词典本身的分册，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刊《藏缅地区语言学》的过刊。

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.
