Crack open the dictionary and pick up a thesaurus, it’s time to talk about a new word–specifically many new words you should know for the ACT / SAT tests. Vocabulary has always been a large element of the ACT, but the newly redesigned SAT will feature a greater emphasis on words and definitions as well.

Vocabulary questions aren’t always going to be as straightforward as: what is the definition of this word? Sometimes context clues will be provided to discover which meaning of the word (through prefixes, suffixes, and roots) is most relevant. For example:

“The recipe calls for condensed milk.”

Given the context of the sentence, the word “condensed” most likely means:

  • A: Shortened
  • B: Made denser
  • C: Concentrated
  • D: Compacted

C is the correct answer here! If you were correct, congratulations! If not, it’s time to study up and learn some new words!

We’ve found quite a few ACT and SAT vocabulary lists that will help you increase your lexicon. We’ll pick out a few from each list. Get ready, logophiles! Here we go.
