Which option describes the use of morphology in vocabulary instruction?

The use of morphology in vocabulary instruction involves analyzing word structures to understand their meanings. Morphology is the study of the structure of words, including the morphemes, which are the smallest units of meaning. By breaking down words into their roots, prefixes, and suffixes, students can gain insights into not just the definition of a word but also how it can change in meaning and use when these elements are altered. This analytical approach enhances vocabulary acquisition by allowing learners to decipher unfamiliar words based on their components, thus expanding their overall understanding and application of language.

In contrast, simply focusing on definitions limits the depth of understanding since it does not address how words are formed or related to one another. Restricting vocabulary to specific subjects confines learners to a narrower scope without leveraging the broader connections between words. Relying solely on memorization techniques might lead to short-term recall rather than deep comprehension, as it often overlooks the structural and systemic characteristics of language that morphology highlights.
