Vocabulary trends from the last two years of official SATs
Updated March 16, 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 March 2026.
After analyzing every SAT vocabulary quiz from March 2024 through March 26, we identified the 28 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 22 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 64 words appeared on exactly two tests. They represent strong candidates for future repetition:
| exhaustive preclude irrefutable sporadic capricious conflate cursory discerning epitomize imperious abound decisive emanate excise expound heterogeneous impervious impugn lambaste unequivocal iconoclasm | outmoded pernicious synopsis testament unnerved heterogeneity exploit insurmountable corroborate appraise alleviate facetious inexplicable rescind surreptitious eclipse copious proxy meticulous refute misconstrue | attrition contentious dearth denote supplant augment harbinger pervade discrepancy partition circumspection epitome supersede perceptible intermingle redundancy incongruence reprisal pretext untenable detrimental counterfactual |
Single-Occurrence Words (163 Words)
These words appeared exactly once across all 2024-2026 SAT administrations. While less frequently tested, they represent important vocabulary that could appear on future exams:
| accommodate aesthetic affinity affront aggregation align amass ambiguous amenable amorphous analogous annihilate anomaly anthropogenic ascribe attest authentic authoritative banal begrudge burgeoning casual catalyze cite coalesce commend complacent confounded conspicuous continuity cryptic culled decouple decry detractor diffusion diminution diminutive discretion disparate disparity dispassionate dispersed disquieting dissonance dogmatic durability dwindling embellished emblematic emissary emulate endearing engender entangled | entanglement entice extemporaneous expansive expedite extensibility extraneous feasible fecund foment forestall forsake foster fraudulent halt halting haughty hypothesize idle immoderate impartial imperative imposing inaugurate inconspicuous indigenous indoctrinate indolence induce inertia inestimable inherent inimical intercede inure invariable invoke irrespective juxtapose magnify mitigate modesty modulate monetizing mutable myriad nebulous neutral nonchalance notional obtrusive occluded orthodox oscillate palpable | paucity permeability pertinent perturbation placate precursor preempts preliminary premiering pretentious propagate provoke prudent quotidian recapitulate reciprocity rectify reiterate renounce replicable resolute retrospect sanction sentimental situate sophist sophisticated steward stipulate subdue subjugate subordinate substantial subsumes subtlety superficial superfluous surmount synthesis tantamount tranquil unambiguous underpinned unfounded universal unsympathetic utilitarian vacillate verisimilitude vindictive visionary warranted wrought |
🎯 Your Study Strategy: The Priority System
Based on this data, here's how to allocate your vocabulary study time:
Priority 1: Master the 28 High-Frequency Words First
These words have the highest probability of appearing on your test. Ensure you can define them, use them in context, and recognize them in various sentence structures. Time investment: 40% of your vocabulary study.
Priority 2: Study the 64 Medium-Frequency Words
These represent strong candidates for repetition. Focus on understanding their roots and relationships to other words. Time investment: 35% of your vocabulary study.
Priority 3: Familiarize Yourself with Single-Occurrence Words
Review these for general familiarity, but don't invest disproportionate time. Many may never repeat. Time investment: 25% of your vocabulary study.

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 28 most-tested words, understand their roots, and build outward from there. The probability math is in your favor.
