An internationally acclaimed linguist, Professor William S-Y. Wang has had a distinguished career both in Hong Kong and abroad. In addition to formulating the theory of lexical diffusion, his academic interests have included experimental phonetic studies, language simulation and modeling and, more recently, aging and language.

In honor of Prof. Wang’s 90th birthday, his colleagues and friends from around the world have contributed more than 30 articles for a two-volume commemorative Festschrift. The contents of this English volume include diachronic, synchronic, and interdisciplinary linguistic studies from authors across Asia and in the United States. Focusing mainly on the Chinese language, topics include the evolution of language, the relationship between language and music, and the functions and processes of the brain involved in language production. Written by and for seasoned language researchers, this Festschrift will also appeal to students of Chinese linguistics and readers with an interest in Chinese culture, history, and neurology.
