What is the primary purpose of vocabulary development in reading instruction?

• A. Expanding students' word knowledge to support comprehension
• B. Improving handwriting
• C. Increasing reading speed only
• D. Reducing test anxiety

Answer: (A)

Expanding students' word knowledge to support comprehension is the main aim of vocabulary development in reading instruction. When learners understand word meanings, nuances, and how words relate to each other, they can interpret sentences more accurately and grasp the author’s message more quickly. This reduces the mental effort spent on figuring out unfamiliar terms, freeing up cognitive resources for predicting, inferring, and connecting ideas across the text. Explicit, systematic vocabulary teaching—introducing high-utility words, teaching word parts, and practicing them in varied contexts—builds durable knowledge that strengthens reading comprehension across genres. The other options miss the primary purpose: vocabulary work isn’t mainly about handwriting, speeding up reading, or reducing test anxiety.
