Which activity helps students determine word meanings and enhances their vocabulary?

• A. Creating lists of synonyms
• B. Using prefixes and suffixes with root words
• C. Memorizing definitions
• D. Completing reading comprehension exercises

Answer: (B)

Using prefixes and suffixes with root words is an effective way to help students determine word meanings and enhance their vocabulary because it empowers them to break down words into their fundamental components. When students understand root words, prefixes (which appear at the beginning of a word), and suffixes (which are added to the end), they can decipher unfamiliar words by applying their knowledge of these elements. This skill not only aids in understanding but also promotes the ability to make educated guesses about the meanings of new words that they may encounter in their reading.

In contrast, creating lists of synonyms focuses on finding words with similar meanings, which can aid vocabulary development but does not directly teach the meanings of new words. Memorizing definitions can lead to rote learning without fostering a deeper understanding or application of the words. Completing reading comprehension exercises is beneficial for overall comprehension skills but does not specifically target vocabulary development through an understanding of word formation. Thus, using prefixes and suffixes enhances vocabulary acquisition by providing a strategic approach to understanding word meanings.
