Based on a case study of the evolution of ';finish' morphemes in Yue and Zhuang Tai-Kadai, this book examines how an internal factor (grammaticalization) and an external factor (language contact) interacted to produce the polyfunctionality of the specific ';finish' morphemes in the languages of Guangxi Zhuang Autonomous Region, Southern China. Arguing that the Central Southern Guangxi Region is a micro-linguistic area, Huang also introduces five unique areal features shared by many of its languages.
