On the ACT Reading Test, you'll encounter questions that ask you to determine the meanings of common words in context. We've identified 200 high-frequency, multiple-meaning words of the sort that you'll see on the exam. As you practice this list, you'll have to rely on context clues in order to determine each word’s meaning in a particular sentence. Be careful! Several of a word's meanings might show up as answer choices — but only one answer will capture the meaning of the word in the context of the sentence.

Learn these words relating to pi, the mathematical constant and the 16th letter of the Greek alphabet. Pi Day is celebrated on March 14th, or 3/14, the date that corresponds to the first (and most well-known) digits in the decimal form of Pi.

Context is king — that’s the lesson you need to internalize as you begin preparing for the vocabulary questions on the SAT. We have identified this pool of 200 words that cut across the disciplines and lend themselves well to context-dependent interpretation. As you learn this list on Vocabulary.com, you will have to rely on context clues in order to determine each word’s meaning in particular sentences. This is the same type of thinking you will need to develop in order to succeed on the SAT! Following our Roadmap to the SAT? Head back to see what else you should be learning this week.
