Fusion

溶合

In some models of phonology, a type of rule which accounts for various processes of feature coalescence; also called merger, and contrasted with fission. In particular, in particle phonology, fusion is a process which merges two root nodes into one, thus providing a mechanism for handling monophthongization.

某些音系学模型中指一类说明各种特征聚结过程的规则；也叫合并，与分裂对立。具体说，在粒子音系学中，溶合是将两个根节点合并为一个的过程，可为单元音化提供一种解释机制。
