派生词部分语法填空中有些单词变形侧重于考查构词法，主要是派生构成法。
派生法（derivation）是英语中重要的构词法，它借助在词干上加词缀的办法来构成新的单词。
一个单词的基本部分称为词干（stem），加在词干前面的部分称为前缀（prefix），加在词干后面的部分成为后缀（suffix）。
一般来说，前缀改变词义，后缀改变词性。
如：在repayment（偿还）一词中，pay付钱，是词干；re-有“返还”之意，是前缀，改变词义；-ment 是后缀，改变词性为名词。
英语中派生词很多。
这里我们只能把常考的派生词按词缀进行归类练习，以提高我们掌握、识记单词的能力。
把课本生词表中的生词记牢才是备考的上策。
