Understanding word families is essential for improving grammar and vocabulary usage because it allows learners to grasp how different forms of a word relate to one another. For instance, recognizing the noun "beauty," the verb "beautify," and the adjective "beautiful," helps learners expand their vocabulary and use various forms appropriately in different contexts.

This knowledge enables students to make accurate grammatical choices when constructing sentences, as they can properly inflect words to match tense, number, or mood as needed. A strong command of word families also facilitates better comprehension of texts, as learners can deduce meanings of unfamiliar words by identifying them as part of a known family.

Other options may seem relevant, but they do not focus as directly on the intertwined development of grammar and vocabulary that word families promote. For instance, understanding literary devices pertains more to literary analysis rather than vocabulary development, listening skills involve aural comprehension, and writing style focuses more on expression and technique rather than foundational vocabulary and grammar. Thus, recognizing and using word families clearly enhances grammatical precision and vocabulary richness.
