Which aspect does semantics deal with?

Semantics focuses specifically on the meaning of words, phrases, sentences, and texts. This branch of linguistics examines how language conveys meaning and how different contexts can alter that meaning. In understanding semantics, one engages with various aspects such as connotations, denotations, and the relationships between different meanings within language.

The other aspects mentioned in the options touch on different fields of linguistic study. For instance, arrangements of sentences relates to syntax, which involves how words are organized to form grammatically correct sentences. The study of sound patterns pertains to phonetics and phonology, which are concerned with the sounds of speech as well as their systematic patterns in a given language. The structure of morphemes is associated with morphology, which deals with the formation and composition of words from their smallest units of meaning. Each of these areas contributes to our understanding of language, but none address the core function of semantics as directly as the meaning aspect does.
