main verb 指句子或从句中表达主要动作、状态或存在的动词(也常叫 lexical verb 实义动词),与 助动词(auxiliary verb) 相对。在含有助动词的结构里,main verb 通常承载核心意义,而助动词主要表达时态、语态、语气等语法信息。
In “She runs,” runs is the main verb.
在 “She runs(她跑步)” 中,runs 是主要动词。
In “The project has been delayed by weather,” delayed is the main verb, while has and been are auxiliaries.
在 “The project has been delayed by weather(项目因天气而被推迟)” 中,delayed 是主要动词,而 has 和 been 是助动词。
/ˈmeɪn vɝːb/ (AmE), /ˈmeɪn vɜːb/ (BrE)
main 源自古英语 mægen,本义与“力量、重要性”相关,后来引申为“主要的、最重要的”。verb 来自拉丁语 verbum(“词、话语”),在语法传统中专指“动词”。合起来 main verb 就是“句子里承担核心意义的动词”。
