What best defines semantics?

Semantics is defined as the study of meaning in language, which includes the meanings of words, phrases, sentences, and texts. It focuses on how individuals comprehend, interpret, and use meaning in verbal communication. When considering this definition, it becomes clear that option B accurately captures the essence of semantics by indicating that it pertains specifically to the meanings associated with words and phrases.

Understanding semantics is crucial in various fields, including linguistics, communication disorders, and language development. It enables effective communication by helping individuals convey and comprehend ideas accurately. In contrast, the other options reference different aspects of language: sentence structure pertains to syntax, sound systems relate to phonology, and social context connects to pragmatics. Each of these areas plays a vital role in communication, but they do not align with the definition of semantics, which focuses exclusively on meaning.
