Using word parts, also known as morphology, in vocabulary instruction is significant because it provides clues to the meanings of words. By understanding prefixes, roots, and suffixes, students can decode unfamiliar words and make educated guesses about their meanings. For instance, if a student knows that the prefix "un-" typically means "not," they can infer that "unhappiness" relates to a negative state in connection to happiness. This morphological knowledge empowers students to expand their vocabulary independently, facilitating a deeper understanding of language and enhancing their comprehension skills across different texts.

The other options do not capture the primary educational benefit of focusing on word parts. While improving writing skills, reading speed, or catering to visual learning styles may be helpful in language acquisition, the core advantage of understanding word parts lies in the ability to unlock the meanings of new and complex vocabulary.
