Which component is considered part of fluency in reading?

Fluency in reading is primarily characterized by speed and correctness. This component ensures that readers can read text smoothly and accurately, allowing them to focus on comprehension instead of struggling with word recognition. When readers possess fluency, they can read at an appropriate pace while maintaining a high level of accuracy, which contributes to a better understanding of the material.

Understanding context is important for comprehension and adds depth to reading skills but is not a direct measure of fluency. Decoding unfamiliar words is a separate skill that falls under phonemic awareness and phonics, which involves the ability to sound out words rather than the fluid reading of known text. Building vocabulary is integral to comprehension and overall literacy but does not specifically define reading fluency itself.

Thus, speed and correctness in reading encapsulate the essence of fluency, making it the correct answer in this context.
