About Book 2: Prefixes

Prefixes are an important part of the English language. Very often a student does not recognize a word or cannot find it in the dictionary because a prefix has been added. There are 2 different aspects to learning prefixes. First, has the word taken a prefix? Second, What is the correct prefix? Both these aspects are dealt with at different times in different units depending on which words came up in the text.

Prefixes: En—  / De— / Un—
