Strategies for Unknown Words

Strategy 1: Eliminate Obvious Wrong Answers

Even if you do not know a word, you can often eliminate choices:

Example: "Laconic most nearly means:" A. Talkative B. Brief in speech C. Musical D. Angry

Even without knowing "laconic," you might eliminate:

  • "Musical" - seems unrelated to a personality trait word
  • "Angry" - common word that would not be tested this way

This leaves A and B, giving you a 50/50 chance.

Strategy 2: Watch for Synonym Traps

If two answer choices mean nearly the same thing, both are usually wrong:

Example: "Serene most nearly means:" A. Angry B. Furious C. Calm D. Loud

"Angry" and "Furious" are synonyms - if one were correct, both would have to be. They are both wrong. Answer: C (Calm)

Strategy 3: Beware Similar-Sounding Distractors

Wrong answers often share word parts with the correct term:

Example: "Benevolent most nearly means:" A. Violent B. Kind C. Blessed D. Beneficial

"Beneficial" shares the root "bene-" but is a trap. "Benevolent" specifically means kind and generous in nature. Answer: B

Strategy 4: Consider Word Tone

Positive words usually have positive answers; negative words have negative answers:

Word ToneLikely Answer Tone
"Benevolent" (positive)Kind, generous, helpful
"Malicious" (negative)Harmful, evil, cruel
"Diligent" (positive)Hardworking, careful
"Negligent" (negative)Careless, irresponsible

Practice Applying Strategies

When you encounter an unknown word:

  1. Break it into parts - Look for familiar prefixes, roots, suffixes
  2. Use context clues - What does the sentence suggest?
  3. Determine tone - Is it positive or negative?
  4. Eliminate wrong answers - Remove obvious mismatches
  5. Make your best choice - Trust your analysis
