 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。

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”—
