Weekly SAT Vocab Quiz: Prefix Power (A-, An-, Anti-, Auto-)
This week’s vocabulary set is all about prefixes—the building blocks that come before a word and give it power. We’re focusing on some high-frequency SAT prefixes:
- A-/An- = without, not (e.g., amoral, anonymous)
- Anti- = against, opposite (e.g., antidote, antithesis)
- Auto- = self (e.g., autonomous, autograph)
Knowing these roots will help you decode unfamiliar words on the test—even if you’ve never seen them before.
Your job:
- Match each word to its definition
- Identify how the prefix influences the meaning
- Apply your understanding with SAT-style multiple-choice questions
Let’s build that root-word recognition and level up your verbal instincts.
