分裂

In some recent models of phonology, it is one of two formal processes used to represent the relationship between monophthongs and diphthongs. In particular, in particle phonology, it refers to the process which spilt one root node into two, thus providing a mechanism for handling diphthongization and other types of “breaking” phenomena.

最近的一些音系学模型中，“分裂”表示单元音和双元音之间关系的两种形式变化之一。具体而言，在粒子音系学中，分裂指一个根节点裂变为两个节点的过程，可用来描写双元音化和其他种类的“裂变”现象。
