Vocabulary trends from the last two years of official SATs
Updated April 15, 2026
With a little help from AI, I've compiled some data trends on the tough vocabulary words that r/SAT moderator "yodatsracist" and roots2words.com have documented for all documented SATs from March 2024 through April 2026.
After analyzing every SAT vocabulary quiz from March 2024 through April 26, we identified the 31 words that the College Board tests most frequently—and the patterns that can help you study smarter, not harder.
Why This Analysis Matters
Here's a truth about SAT prep that most test-takers don't realize: the College Board recycles vocabulary. Not occasionally—systematically. After compiling data reported by r/SAT forums and roots2words.com from 23 official SAT administrations spanning over two years, we discovered that certain words appear on three, four, five, even six different tests.
This isn't random. These high-frequency words represent the vocabulary the College Board considers essential for college readiness. If you're serious about maximizing your SAT score, these are the words that deserve your attention first.

Pattern Analysis: What the Data Reveals
1. Root Word Families Dominate
The College Board clearly favors words that share Latin and Greek roots. Notice how these word families appear repeatedly:
The EQUI- Family (equal): equivocal, unequivocal
The -GRUOUS Family (fitting): incongruous, incongruence
The -SCRIBE/-SCORE Family (write): underscore, ascribe
The -MINATE/-MINE Family: undermine, enumerate
The -DICATE Family: vindicate, indicate
Strategic Takeaway: Learning root words gives you leverage across multiple vocabulary questions. Master one root, recognize many words.
2. Negative Prefixes Are High-Value Targets
Words with negative prefixes (un-, in-, ir-, im-) appear disproportionately in high-frequency lists:
- INCONGRUOUS (3x)
- ANOMALOUS (3x)
- INEXPLICABLE (2x)
- IRREFUTABLE (2x)
- INSURMOUNTABLE (2x)
- IMPERVIOUS (2x)
Strategic Takeaway: Pay special attention to words that negate or reverse meaning. The SAT loves testing whether students understand how prefixes transform word meaning.
3. The November-May Connection
Our analysis revealed an interesting pattern: November 2024 and May 2025 share an unusually high number of words. This suggests the College Board may reuse word banks across certain testing windows.
Words appearing on both tests: alleviate, ameliorate, anomalous, eschew, equivocal, evince, exacerbate, facetious, idiosyncratic, inexplicable, precede, proponent, rescind, surreptitious, tenuous, ubiquitous, vindicate
College Board clearly has favorites—and now you know what they are.
4. August Tests Feature the Most Vocabulary
August 2025 US contained 38 vocabulary words—the highest concentration of any single administration. Students taking August tests should prepare for vocabulary-heavy passages.
📊 Complete Frequency Distribution
Medium-Frequency Words (2 Appearances)
These 61 words appeared on exactly two tests. They represent strong candidates for future repetition:

Methodology Notes
This analysis compiled vocabulary from official SAT administrations as reported by test-takers on r/SAT. Word variants (e.g., "proponents" and "proponent," "eschewed" and "eschew") were normalized to base forms for accurate frequency counting.
We identified and excluded apparent duplicates where the same quiz data appeared under multiple labels, ensuring each test administration was counted only once.
What This Means for Your Prep
The SAT isn't testing random vocabulary—it's drawing from a defined pool of words the College Board considers essential. By focusing on high-frequency words first, you're aligning your study time with the test's actual patterns.
This data-driven approach means you can study smarter: master the 29 most-tested words, understand their roots, and build outward from there. The probability math is in your favor.
