Semantics is primarily concerned with what aspect of language?

Semantics primarily deals with the definition of words and the meanings ascribed to them in a language. This encompasses not just individual words but also phrases, sentences, and larger units of expression. In understanding semantics, one looks at how meanings are constructed, understood, and interpreted in communication. It is the study of how language represents ideas, concepts, and relationships, which is fundamental to effective communication.

While the other options touch on important aspects of language, they do not encompass the core focus of semantics. For example, organizing sounds relates to phonetics and phonology, the relationship between language and its users pertains to sociolinguistics or pragmatics, and emotional tone relates to the study of pragmatics and semantics but is more about affective communication rather than the direct meaning of words. Therefore, the correct answer highlights the central function of semantics in examining and interpreting language through the meanings of its components.
