Sino-Tibetan Etymological Dictionary and Thesaurus

The Sino-Tibetan Etymological Dictionary and Thesaurus (commonly abbreviated STEDT) was a linguistics research project hosted at the University of California at Berkeley. The project, which focused on Sino-Tibetan historical linguistics, started in 1987 and lasted until 2015.

James Matisoff was the director of STEDT for nearly three decades.

The Linguistics of the Tibeto-Burman Area journal, now published by Benjamins Pub. Co., was also part of the STEDT project. In addition, the International Conferences on Sino-Tibetan Languages and Linguistics (ICSTLL) were mostly organized by STEDT project members since the 1990s.

Overview
In 1987, James Matisoff began the Sino-Tibetan Etymological Dictionary and Thesaurus (STEDT) project, which aimed to produce an etymological dictionary of Sino-Tibetan languages organized by semantic field. The project maintains a large, publicly accessible lexical database of nearly one million records, with data on Sino-Tibetan languages from over 500 sources. This database is used to identify and mark cognates for the purposes of better understanding the historical development of the Sino-Tibetan language family and the subgroupings of the languages therein, and to reconstruct the theoretical proto-language of the language family. The project was funded by the National Science Foundation (NSF) and the National Endowment for the Humanities (NEH).

Members
Project members were known as "STEDTniks," and included Richard S. Cook, Zev J. Handel, Randy J. LaPolla, David Mortensen, Jackson Tianshin Sun, Jonathan P. Evans, Weera Ostapirat, Graham Thurgood, David Solnit, Kenneth VanBik, John B. Lowe ("J.B. Lowe"), Liberty Lidz, Daniel Bruhn, Dominic Yu, among other linguists.

Publications
Preliminary results from the STEDT project were published in Matisoff's 2003 monograph Handbook of Proto-Tibeto-Burman: System and Philosophy of Sino-Tibetan Reconstruction (HPTB). In 2008, Matisoff published a monograph on Proto-Tibeto-Burman reconstructions for reproductive system vocabulary.

The final release of the Sino-Tibetan Etymological Dictionary and Thesaurus was published in 2015 by Matisoff, with an online version also available.

Monographs
The STEDT Monograph Series, published by the STEDT project, has 10 books.
