What encompasses an understanding of word meanings and usage?

The concept of word meanings and usage is best encapsulated by word knowledge. This refers to a person’s familiarity with words, including their definitions, nuances, and appropriate contexts for use. Individuals with strong word knowledge understand not only the meanings of words but also how to apply them correctly in various situations, which is crucial for effective communication.

Vocabulary skills and lexical awareness could be considered related. Vocabulary skills focus more broadly on the ability to recognize, understand, and produce a range of words. While this overlaps with word knowledge, it does not specifically capture the depth of understanding regarding the meanings and usage of words. Lexical awareness deals with the recognition of words and their properties, but may not emphasize their meanings as prominently as word knowledge does.

Language proficiency is a wider term that encompasses overall ability in a language, including speaking, listening, reading, and writing skills. Though it includes an understanding of word meanings and usage, it does not focus specifically on the depth of understanding that constitutes word knowledge. Hence, word knowledge is the most precise answer in this context, illustrating a clear understanding of how words function within a language.
