Context clues are useful when:

• A. Understanding the meaning of words that are not familiar
• B. Memorizing vocabulary by heart
• C. Improving handwriting
• D. Analyzing sentence structure only

Answer: (A)

Context clues let you figure out the meaning of unfamiliar words by using hints from the surrounding words and sentences. When you encounter a new word, nearby details—like a definition tucked into the sentence, a synonym or antonym, or an example—help you infer what the word means. This makes reading smoother and helps you understand the message without constantly stopping to look up words. So, understanding the meaning of words you don’t know is the best fit for how context clues are used. Memorizing vocabulary by heart isn’t about using clues from the text, handwriting isn’t related to word meaning, and focusing only on sentence structure ignores how clues in context reveal meaning.
