Prefix

定义 Definition

prefix（名词）指“前缀”：加在词根或词首前，用来改变词义或构成新词的构词成分（如 *un-、re-、pre-*）。也可指“编号/名称前的前置部分”（如电话区号），但最常见的是语言学里的“前缀”。

发音 Pronunciation (IPA)

/prifks/

例句 Examples

A prefix can change the meaning of a word.
前缀可以改变一个单词的意思。

By adding the prefix “un-,” the word “happy” becomes “unhappy,” which expresses the opposite meaning.
加上前缀“un-”后，“happy”变成“unhappy”，表达相反的意思。

词源 Etymology

来自拉丁语 praefixus，意为“固定在前面的”，由 **prae-**（在……之前）+ fixus（固定的）组成。后来进入英语，用来指“加在词前的成分”。
