<p>I know direct hits is good for actual SAT words, but does anyone know a good book for learning roots?</p>
<p>Gruber’s Complete SAT Guide</p>
<p>Has roots, suffixes, affixes, all that wonderful stuff.
And a huge list of 3400 Vocab words to add to the Direct Hits books.</p>
<p>I suggest try Merriam Webster’s Vocabulary Builder, with suffixes roots and so on.</p>
