Rheme

述位

In the Prague School approach to linguistics, a term distinguished from theme, as part of an analysis of the information structure of messages, within an overall theoretical framework known as functional sentence perspective. The rheme is defined as the part of a sentence which adds most to the advancing processing of communication; in other words, it expresses the largest amount of extra meaning, in addition to what has already been communicated.

近年来布拉格学派的语言学研究中，“述位”与主位对立，一起在称作功能句法观的总体理论框架中用来分析信息的结构。述位定义为句子中最能推进信递过程的那个部分；换言之，述位表达除已经传递的信息外最大部分的新增意义。
