Why is vocabulary instruction critical in elementary reading?

• A. It speeds up decoding alone.
• B. It supports comprehension.
• C. It is only for advanced readers.
• D. It replaces decoding.

Answer: (B)

Knowledge of word meanings directly influences how well a reader understands text. When students know many of the words they encounter, they can retrieve meanings quickly, follow sentence logic, and connect ideas across sentences, which strengthens comprehension. Explicit vocabulary instruction builds students’ semantic networks and helps them use context and word parts to infer meaning of unfamiliar words, supporting reading across genres and subjects. It’s essential for all learners, not just advanced readers, and it complements decoding rather than replacing it; decoding gets words into awareness, but understanding them is what allows true reading fluency.
