As we cover in our Conquer SAT Vocabulary video course, when you come across a vocab word you don’t know on the SAT, there are a few ways to deal with it. The first involves checking for context clues, and the second involves taking the word apart, so to speak, to examine its prefix, suffix, or root. If you’re familiar with these common prefixes, suffixes, and roots, you’re more likely to be able to guess at the meaning of the word.

Here’s a list of some of the most common prefixes, suffixes, and roots on the SAT. If you memorize these prefixes, suffixes, and roots, vocabulary words that employ them should be a breeze!
