最近开始看 NLP 的论文啊，觉得好多术语都不知道是个什么，就只能一边看一边查咯。

Predicate：谓词

Link

The predicate is the part of a sentence (or clause) that tells us what the subject does or is. To put it another way, the predicate is everything that is not the subject.

或参照韦氏词典的定义：

the part of a sentence or clause that expresses what is said of the subject and that usually consists of a verb with or without objects, complements, or adverbial modifiers.

简而言之谓词是描述 Subject 做什么或者是什么的一个成分，并不一定是一个词。一个谓词的 Core 是一个动词。
