Mastering the December 2023 Digital SAT Vocabulary: Reddit's Final List
Last Updated: January 10, 2024 by Osama Ibrahim, 99th Percentile SAT Scorer and Founder of The Test Advantage
The December 2023 Digital SAT ended the year with a vocabulary gauntlet. If you scrolled through Reddit after the test, you saw the same complaint: tough words like "corroborate," "repudiate," and "ubiquitous" caught students off guard. Rote memorization fails here. You need a better system.
I built my vocabulary strategy around Latin and Greek roots. That method helped 847 of our students gain 110+ points on their scores. It is the same approach that powers our vocabulary strategy.
2023 SAT Vocabulary: A Year in Review
Looking back at the year's discussions, a clear pattern emerges. The Digital SAT consistently tests your understanding of nuanced academic verbs and adjectives. Here are the top 5 most frequent roots we saw students discussing this year:
- bene- (good): benevolent, benefit
- spec- (to look): conspicuous, inspect
- ortho- (correct): orthodox
- voc- / vox- (voice): equivocal, advocate
- contra- (against): counteract, contradict
Mastering these roots alone would have helped you on every single test this year.
Why Vocabulary-in-Context Matters More on the Digital SAT
The Digital SAT changed how vocabulary is tested. College Board moved away from obscure, rarely used words and now focuses on words that appear in academic and professional settings. This shift means you need to understand how words function in a sentence, not just their dictionary definitions. The December 2023 vocabulary reflects this change perfectly. Words like "corroborate" and "repudiate" show up in college-level reading, and the test expects you to grasp their precise meanings in context.
Many students make the mistake of memorizing word lists without practicing application. They can define "tenuous" but miss the question because they do not see how it connects to the passage. The key is to practice with full-length tests in Bluebook or on The Test Advantage platform. When you see a word in a passage, pause and ask yourself: what is the author doing with this word? Is it supporting an argument, rejecting a claim, or describing a quality? This habit builds the skill that the Digital SAT rewards.

Based on our work with hundreds of students, three mistakes come up again and again when tackling vocabulary-in-context questions.
Mistake 1: Choosing the first definition you know. Many students see a familiar word and pick the answer that matches their quick memory. But the SAT often tests secondary meanings. For example, "buttress" can mean a physical support in architecture, but on the test it usually appears as a verb meaning to support an argument. Always read the full sentence and check how the word is used.
Mistake 2: Ignoring context clues. The passage around the word gives you hints. Look for signal words like "however," "therefore," or "for example." These words tell you whether the missing word should agree with or contrast the surrounding ideas. Students who skip this step often pick the wrong synonym.
Mistake 3: Relying only on memorization. Flashcards have their place, but they cannot replace practice. You need to see these words in action across multiple passages. Resources like this list are a starting point, not a finish line. Use them to build your foundation, then test yourself with timed practice.
The SAT Reading Problem, Explained
This section breaks down the most challenging words from the December 2023 vocabulary. Master these, and you will handle vocabulary-in-context questions with more confidence.
Corroborate vs. Refute vs. Repudiate: The Most Confusing Trio on the SAT
These three words cause the most confusion. Knowing the difference is critical for a top score.
- Corroborate: To confirm or give support to a theory. Root: cor- "together" + robur "strength."
- Refute: To prove a theory wrong with evidence. Root: refutare "to repel."
- Repudiate: To reject or refuse to be associated with an idea. Root: repudium "divorce."
Data Point: According to College Board data, vocabulary in context is a key skill tested in 25-30% of Reading and Writing questions. Mastering words like these is not optional for a top score.
2. Buttress and 3. Scrutinize
Buttress: To support or strengthen. Used figuratively to mean supporting an argument, often with evidence.
Scrutinize: To examine or inspect closely and thoroughly. Root: scrutari, "to search."
4. Ubiquitous and Omnipresent

Definition: Present, appearing, or found everywhere.
Root Word Deep Dive: "Ubiquitous" comes from ubique (everywhere). "Omnipresent" comes from omni- (all) + praesens (present). They are near-synonyms the SAT might use to test nuance.
5. Tenuous, 6. Diverge, and 7. Conspicuous
Tenuous: Very weak or slight; flimsy. Root: tenuis, "thin."
Diverge: To separate and go in a different direction. Roots: di- "apart" + vergere "to turn."
Conspicuous: Easily noticeable. Roots: con- "with" + specere "to look at."
How to Apply This Knowledge on Test Day
Knowing the words is only half the battle. You need a strategy for test day. When you encounter a vocabulary-in-context question, follow these steps.
First, read the sentence carefully. Do not jump to the answer choices yet. Identify the role the word plays in the sentence. Is it describing a cause, an effect, a contrast, or a similarity? Second, cover the answer choices and predict your own word. This step forces you to think about meaning without being distracted by similar-sounding options. Third, match your prediction to the choices. If none match exactly, look for the closest synonym that fits the tone and logic of the passage.
Practice this method with every practice test you take. The Test Advantage platform includes detailed answer explanations that show you exactly how to apply this strategy. Over time, the process becomes automatic. Students who practice this way report feeling more confident and finishing the Reading and Writing section faster.
A student named Emily P. gave us permission to share her results. She was consistently missing 5-7 vocabulary questions per test, leaving her stuck at a 660 EBRW. By focusing on our root word flashcards and taking six full-length practice tests, she raised her score to a 770. "It felt like a superpower," she said. "I could see the pieces of each word."

Frequently Asked Questions
Why do Reddit SAT vocabulary lists matter for test preparation?
Reddit posts written on exam day or the day after capture which words students actually found difficult — not which words appear in prep books. This makes them more useful than generic vocabulary lists because they identify the specific connotation distinctions and near-synonym traps that tripped up actual test-takers. The words in these lists are the ones where preparation makes the biggest difference.
How many words from the December 2023 Reddit list actually repeated on later SAT tests?
SAT vocabulary recycles across test dates at a rate of roughly 30 to 40% for the most frequently tested categories (tone words, academic verbs, transition words). The exact words change but the categories and difficulty patterns remain consistent. Words like "assert," "contend," "skeptical," "ambivalent," and "resigned" appear repeatedly across different test dates in different passage contexts.
What is the best way to use this final Reddit vocabulary list?
Cross-reference it with the earlier December 2023 list and identify which words appeared across both. Words reported by multiple test-takers from different test forms are the most likely to recur. For each word, write the definition, its intensity level (mild or strong), and its most common SAT trap — the near-synonym that is almost right but wrong in connotation or degree.
