Greek and Latin Roots: The Foundation of Vocabulary
Did you know that over 60% of English words have Greek or Latin roots? Mastering just 50 root words can help you decode thousands of English words—a game-changing strategy for standardized tests.
Why Roots Matter for Test Success
On standardized tests like the SHSAT, ISEE, and SSAT, you'll encounter unfamiliar words. Rather than memorizing thousands of individual words, learning roots allows you to:
- Infer meanings of words you've never seen before
- Remember vocabulary more easily by understanding word families
- Build confidence when facing challenging reading passages
- Expand your vocabulary exponentially with each root learned
