Which skill reflects the proper use of nouns, pronouns, verbs, and adjectives?

The choice regarding word usage skills is the most appropriate because it specifically encompasses the proper application and understanding of nouns, pronouns, verbs, and adjectives within language. Mastery of word usage involves knowing how to select and apply these parts of speech correctly to convey meaning and maintain clarity in writing and speech. This includes understanding how each type of word functions within a sentence, ensuring that they agree in number and gender where applicable, and using them according to standard conventions of the English language.

Punctuation and capitalization skills focus on the rules governing the use of punctuation marks and the correct writing of capital letters, which, while important for overall writing quality, do not directly relate to the use of specific parts of speech. Sentence-processing skills pertain more to how sentences are constructed and understood as complete units, rather than specific word-level usage. Lastly, style skills involve the choice of language that reflects an author’s voice or the tone of the writing, which is broader and more subjective than the concrete aspect of correctly using nouns, pronouns, verbs, and adjectives. Thus, word usage skills is the most relevant choice in this context.
