 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。

oppose = op + pos(放)+ e → 反着放 → v. 反抗,对立
opposite = op + posit(放)+ e → 对这放 → n. 对立面
opposite = op + posit(放)+ e → 对这放 → a. 对立的
—② 表示“加强”—
oblige = ob + lig(捆绑)+ e → 牢牢的绑住 → v. 迫使,束缚
observe = ob + serv(保持;服务)+ e → 一再坚持;坚持(看)→ v. 遵守;引申为观察
