Strategies for Unknown Words

1. Read the Entire Sentence Don't stop at the unknown word—context often comes after.

2. Look for Clue Words Signal words point to definitions, synonyms, or antonyms.

3. Consider Word Parts

  • Prefixes (un-, pre-, anti-)
  • Roots (cardi-, derm-, neuro-)
  • Suffixes (-itis, -ology, -ectomy)

4. Substitute Your Guess Replace the unknown word with your guess—does the sentence still make sense?

5. Eliminate Wrong Answers If multiple choice, cross out options that don't fit the context.

Practice with Context

Example: "The patient's edema, the swelling in her ankles, had decreased after treatment."

Analysis:

  • Clue type: Definition
  • Signal: "the swelling"
  • Meaning: Edema = swelling

Example: "Unlike his garrulous roommate, John was quiet and reserved."

Analysis:

  • Clue type: Antonym
  • Signal: "Unlike" and "quiet"
  • Meaning: Garrulous = talkative (opposite of quiet)
