GRE Vocabulary: High-Frequency Tier 2 Words (Mercurial to Tendentious) – Complete Study Guide

For serious GRE candidates aiming 320+

What This Is

The GRE tests Tier 2 vocabulary—words that appear frequently in high-level academic and professional writing but are rarely used in everyday speech. These words often serve as distractors in Text Completion and Sentence Equivalence questions, where ETS exploits subtle differences in meaning to trap test-takers. Mastering them boosts your Verbal score by 3–5 points by eliminating wrong answers and confidently selecting the best fit.

Example GRE-Style Question:
The CEO’s _ decision-making—shifting strategies abruptly one day and reversing course the next—left her team exasperated and unable to plan effectively. A) mercurial B) dogmatic C) obsequious D) tendentious E) laconic

(Correct answer: A) mercurial. The clue is "shifting strategies abruptly" and "reversing course," which describe unpredictable, changeable behavior.)

Key Concepts & Techniques

1. Root + Context Clues
2. What it is: Break words into roots (e.g., mercury = quicksilver → mercurial = changeable) and use sentence context to infer meaning.

3. When to use it: When you don’t know the word but can spot a clue (e.g., "abruptly," "reversing course" in the example above).

4. Connotation Matching

5. What it is: Words have positive, negative, or neutral tones. Match the word’s connotation to the sentence’s tone.

6. When to use it: When the sentence has a clear emotional charge (e.g., "exasperated" in the example signals a negative word like mercurial).

7. Process of Elimination (POE) for Synonyms

8. What it is: In Sentence Equivalence, eliminate words that don’t have a synonym pair in the options.

9. When to use it: When two words seem similar but only one has a matching pair (e.g., dogmatic and obdurate are synonyms; mercurial does not).

10. Blank-First Strategy

11. What it is: Read the sentence without looking at the options, predict a word for the blank, then match to the choices.

12. When to use it: For Text Completion with strong contextual clues (e.g., "shifting strategies abruptly" → predict "unpredictable").

13. Tier 2 Word Families

14. What it is: Group words by shared roots or themes (e.g., mercurial, capricious, fickle all mean "changeable").

15. When to use it: When you know one word in a family, use it to guess others (e.g., mercury → mercurial = quick/changeable).

16. False Friends Trap

17. What it is: Words that look familiar but mean something else (e.g., tendentious ≠ tender; it means "biased").
18. When to use it: When a word seems "easy" but doesn’t fit the context—double-check definitions.

Step-by-Step Strategy

For Text Completion (Single Blank)

1. Read the sentence carefully, underlining clues (e.g., "exasperated," "shifting strategies").
2. Predict a word for the blank before looking at options (e.g., "unpredictable").
3. Match your prediction to the closest word in the options (e.g., mercurial = unpredictable).
4. Eliminate wrong answers using connotation and context (e.g., dogmatic = rigid, not fitting "shifting").
5. Confirm the best fit by plugging it back into the sentence.

For Sentence Equivalence (Double Blank)

1. Read the sentence, underlining clues and contrast words (e.g., "although," "despite").
2. Predict a word for the first blank, then look for a synonym pair in the options.
3. Eliminate words without a pair (e.g., if mercurial is an option but has no synonym, it’s wrong).
4. Check the second blank for consistency with the first.
5. Verify both words fit the sentence’s logic and tone.

Fully Worked GRE-Style Example

Question:
The professor’s lectures were notoriously _; she would digress into tangential anecdotes, leaving students confused about the core topic. A) didactic B) discursive C) laconic D) tendentious E) obsequious

Step-by-Step Solution:
1. Underline clues: "digress into tangential anecdotes," "confused about the core topic." 2. Predict a word: "rambling" or "wandering off-topic." 3. Match to options:
- Didactic = teaching-focused (neutral, not a fit).
- Discursive = rambling, digressive (matches prediction).
- Laconic = brief (opposite of rambling).
- Tendentious = biased (irrelevant).
- Obsequious = overly obedient (irrelevant).
4. Eliminate wrong answers: A, C, D, E don’t fit.
5. Confirm: Discursive = digressive, fits perfectly.

Answer: B) discursive.

Common Mistakes

1. Mistake: Assuming a word means what it sounds like (e.g., tendentious = "tender").
2. Why it happens: Over-reliance on phonetics.

3. Correct approach: Always check roots (e.g., tendere = "to stretch" → tendentious = "stretched" toward a bias).

4. Mistake: Ignoring connotation (e.g., picking mercurial for a positive sentence).

5. Why it happens: Focusing only on definition, not tone.

6. Correct approach: Match the word’s charge to the sentence (e.g., mercurial is negative; capricious is neutral/negative).

7. Mistake: Overlooking contrast words (e.g., "although," "but").

8. Why it happens: Skimming the sentence.

9. Correct approach: Circle contrast words—they signal the blank’s meaning is opposite of the surrounding text.

10. Mistake: Picking a word that "sounds smart" but doesn’t fit (e.g., obsequious in a neutral context).

11. Why it happens: Trying to impress rather than solve.
12. Correct approach: Prioritize fit over impressiveness—the GRE rewards accuracy, not vocabulary showboating.

GRE Traps & Timing

Traps to Avoid

1. False Synonyms: ETS pairs words that seem similar but aren’t (e.g., mercurial vs. volatile—both mean "changeable," but mercurial implies mood swings, while volatile implies explosive).

2. How to spot: Look for subtle differences in intensity or context.

3. Overlapping Definitions: Words like dogmatic (rigid in beliefs) and obdurate (stubborn) overlap but aren’t always interchangeable.

4. How to spot: Check if the sentence specifies what the person is stubborn about (e.g., dogmatic = beliefs; obdurate = refusal to change).

5. Tone Mismatch: Laconic (brief) and taciturn (silent) both describe speech, but laconic is neutral, while taciturn is negative.

6. How to spot: Ask: "Does the sentence criticize or describe?"

Timing

• Text Completion (1 blank): 45–60 seconds.
• Text Completion (2–3 blanks): 75–90 seconds.
• Sentence Equivalence: 60–75 seconds.
• If stuck: Flag and return—don’t waste >2 minutes on one question.

Quick Practice

1. Question:
   The journalist’s _ article, which presented only one side of the controversial issue, was criticized for its lack of objectivity.
   A) tendentious
   B) mercurial
   C) laconic
   D) obsequious
   E) didactic

Answer: A) tendentious. The clue is "presented only one side" and "lack of objectivity," which describe bias.

1. Question:
   Despite his _ demeanor in public, the CEO was known to be fiercely competitive behind closed doors.
   A) obsequious
   B) phlegmatic
   C) mercurial
   D) tendentious
   E) laconic

Answer: B) phlegmatic. The contrast is "fiercely competitive," so the blank needs a word meaning "calm/unemotional."

Last-Minute Cram Sheet

1. Mercurial = unpredictable, changeable (like mercury’s quicksilver). ⚠️ Not the same as volatile (explosive).
2. Dogmatic = rigid in beliefs; obdurate = stubborn in action. ⚠️ Dogma = doctrine.
3. Tendentious = biased, pushing an agenda. ⚠️ Not "tender" or "gentle."
4. Laconic = brief, concise (neutral); taciturn = silent (negative).
5. Discursive = rambling, digressive. ⚠️ Not "discussive" (which isn’t a word).
6. Obsequious = overly obedient/flattering. ⚠️ Not "obstinate" (stubborn).
7. Phlegmatic = calm, unemotional. ⚠️ Not "phlegmy" (related to mucus).
8. Capricious = impulsive, whimsical; mercurial = mood-based change.
9. Didactic = teaching-focused (neutral/positive); pedantic = overly concerned with rules (negative).
10. Trap Pair: Mercurial vs. volatile → mood swings vs. explosive change.

Final Tip: For Tier 2 words, focus on roots and connotation first, then memorize one GRE-style sentence for each word (e.g., "Her mercurial moods made planning impossible"). This beats flashcards alone.
