你要学会掌握派生词的规律就不怕了。派生词即由一个词根加词缀构成新词，如：一、加前缀：like--dislike--unlike;tell--retell;able--enable;二、加后缀：usual--usually;soft--soften;use--useful--usefulness;hero--heroic;三、加前缀和后缀：order--disorderly;usual--unusually;forget--unforgettable等等。

楼主有些是非常基本的，不值得一找的！有两个地方可以找到同一份pdf文件，为《Webster's Third New International Dictionary, Unabridged》中所有Prefixes, Suffixes, and Combining Forms的总和，在：这是仅次于《Oxford English Dictionary》中的集成。还有一本书也许能找到，尽管主要是生物类：Borror, D. J. (1960). Dictionary of Word Roots and Combining Forms Compiled from the Greek, Latin, and Other Languages, with Special Reference to Biological Terms and Scientific Names. Palo Alto, CA: N-P Publications; Mayfield Publishing Co.不要把英语学成汉语！进步。
