 一个英语单词可分为三部分:前缀(prefix)词根(root)后缀(suffix)。位于词根前面的部分就是前缀。前缀,可以改变单词的意思。

irrational 1 = ir + rational(合理的)→ a. 不合理的

irregular = ir + regular(规则的)→ a. 不规则的

irrelevant 2 = ir + relevant(相关的)→ a. 不相关的



— kilo-表示“千”—

kilogram = kilo + gram(克)→ n. 千克(gram作为词根表示“写,画”)

kilometer = kilo + meter(米)→ n. 千米(meter作为词根表示“计量,测量”)



—milli-表示“千分之一”—

milligram = milli + gram(克)→ n. 毫克

millimeter = milli + meter(米)→ n. 毫米

millisecond = milli + second(秒)→ n. 毫秒 



—mis-表示“错误,坏”—

misfortune = mis + fortune(运气)→ n. 不幸;灾难

misunderstand = mis + understand(明白)→ v. 误解

misuse 3 = mis + use(用)→ 错误的用 → v./n. 误用;
