The book "Predicate Compounding in the YiGroup: The Continuum of Grammaticalization Studia Typologica [STTYP] 3 German Edition" offers an in-depth examination of the evolution of technology and its impact on human survival and unity in a warring world. The author argues that understanding the process of technological development is crucial for the future of humanity, and that developing a personal paradigm for perceiving this process is essential for our survival and unity. The book begins by exploring the early phases of grammaticalization, specifically the productive metaphorical process displayed in the verbs of the YiGroup BurmeseLolo languages from southwest China. This process is based on the notion of transfer metaphor and the hierarchical structure of metaphorical processes, which leads to the creation of new products within the realm of delimitation phase and resultative state. While the similarities in sound structure among these products suggest a genetic relationship between the BurmeseLolo languages, the underlying metaphorical processes reveal significant differences.
