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.
