What level of language relates to the meanings of words?

The correct answer pertains to semantics, which is the branch of linguistics concerned with the meaning of words, phrases, and sentences. Semantics involves understanding how meanings are constructed, interpreted, and the relationships between different meanings. This level of language is essential for effective communication since it focuses on how language conveys meaning beyond mere sound or structure.

The other levels of language, such as phonology, which deals with the sounds of speech; syntax, which is concerned with the arrangement of words to create meaningful sentences; and the lexicon, which refers to the inventory of words and their meanings in a language, all play important roles in language use. However, none of these specifically focus on the meanings of words in the way that semantics does. Therefore, semantics is the most accurate choice for discussing the meanings associated with words.
