Structural analysis in reading focuses on which of the following?

Structural analysis in reading is a method that emphasizes decoding words by breaking them down into their morphemes, which are the smallest units of meaning. This includes roots, prefixes, and suffixes. By utilizing knowledge of morphemes, students can better understand the structure of words, which in turn aids in comprehension and vocabulary development. For example, recognizing that the root "graph" relates to writing can help students understand words like "autograph" or "biography."

Understanding sentence context may enhance comprehension, but it does not specifically focus on the structural elements of words themselves. Pronunciation is important for reading fluency, but it does not involve analyzing the internal parts of words. Improving reading fluency involves speed and accuracy in reading, which can be supported by structural analysis but is not the main focus of this approach. Thus, focusing on morphemes is central to structural analysis, making it the correct answer.
