Abstract: Disyllabification is a particular linguistic phenomenon, which appeared in the evolution of Chinese in middle ages. As a basic form of Chinese rhythm, it is one of the starting points of the study of Chinese rhythmic syntax. It is generally recognized that disyllabification is quite simple, since it is just a disyllabic cluster and a main form of Chinese words. However, it is by no means simple since from a diachronic and dynamic perspective disyllabification has at least two important results:the effect of pivot in constructing Chinese hierarchical system, and the effect of integration in shaping Chinese morphology.

Key words: disyllabification, two-character group, hierarchical system, word-formation model, conceptual integration
