There are more native speakers of Sino-Tibetan languages than of any other language family in the world. Records of these languages are among the oldest for any human language, and the amount of active research on them, both diachronic and synchronic, has multiplied in the last few decades. This volume includes overview articles as well as descriptions of individual languages and comments on the subgroups in which they occur. In addition to a number of modern languages, there are descriptions of several ancient languages.

This pioneering book is the prototype of the etymological thesaurus that has been the goal of the Sino-Tibetan Etymological Dictionary and Thesaurus project (STEDT) since 1987. It presents nearly 170 Proto-Tibeto-Burman etymologies in the semantic area of the reproductive system, along with discussions of possible Chinese cognates. Special attention is paid to patterns of semantic associations between the reproductive system and other areas of the lexicon.
