词根是指单词的最核心部分 任何单词都是由词根扩展的 例如这个里面的http://iselong.com/7/527.htm
词尾和后缀差不多 例如ing ed er 等等
Ⅲ 英语的词缀词根各代表什么
词根(roots)是一个词最根本、最核心且不能加以分析的部分。词干(stems) 是加后缀之前词根的变形。
例如：modify 修改，-modi- 为词干，-mod- 为词根，-fy 为后缀；denial否认，-deni- 为词干、-deny- 为词根、-al为后缀。有时为了方便学习，我们把词干称为词根的变体。
词缀可以分为前缀（多表示意义）和后缀（多表示词性）。 如ab-,abs-加在词根前，表示"相反，变坏，离去"abnormal反常的（ab+normal正常的）。
单词一般由三部分组成：词根、前缀和后缀。词根决定单词意思，前缀改变单词词义，后缀决定单词词性。

你可以这样理解 “在计算出结果之前进行的事情”不就是预告吗，这样也有利于你记忆单词。
Ⅷ 英语fore前缀是什么意思
fore本身就是个前缀带有前面前锋、前面的意思。词根、词缀记忆法利用单词专的分拆、属谐音和词与词之间的联系来记忆单词。通过这种方法背单词，事半功倍且遗忘率较低。
fore－表示＂前面，预先＂
forestall阻止。
forebode预兆；凶兆。
forefather前人，祖先。
forearm前人，祖先。
forecast预料。
