The document discusses using context clues versus dictionaries to determine the meaning of unknown words. It notes that on tests like the SAT, no dictionaries are allowed, so test-takers must rely on context clues. While dictionaries directly define words, context clues provide hints about a word's meaning from how it is used in surrounding sentences. Both skills are important to develop. The document demonstrates determining the definition of "quaint" from context clues and provides examples of different types of context clues that may be presented in passages. It emphasizes the importance of practicing using context clues for situations when a dictionary cannot be used.
