Why is vocabulary important in reading comprehension?

Vocabulary is crucial for reading comprehension because it enables effective communication through word knowledge. When readers encounter words they understand, they can make sense of sentences and overall meanings more easily. A rich vocabulary allows readers to grasp nuances, figurative language, and the specific contexts in which words are used, enhancing their ability to interpret and connect ideas within the text. This understanding fosters critical thinking and the ability to engage in discussions about what they read, further promoting learning and retention.

The other options, while they touch upon aspects related to reading, do not directly address the primary role vocabulary plays in comprehension. For example, while pronunciation can be aided by vocabulary knowledge, it does not directly impact comprehension. Similarly, increasing reading speed is beneficial but does not necessarily mean that the reader understands the material. The notion that vocabulary is only necessary for advanced readers also overlooks the foundational role that vocabulary plays for readers at all levels, as vocabulary development is essential from the earliest stages of literacy.
