What is syntax concerned with in a language?

Syntax refers to the set of rules, principles, and processes that govern the structure of sentences in a language, specifically how words and phrases are arranged to create meaningful expressions. This includes the order of words, the agreement between subjects and verbs, and the way different parts of sentences connect with one another. Understanding syntax is essential for constructing grammatically correct sentences and for interpreting the meaning conveyed by those structures in communication.

The other aspects mentioned, such as pronunciation (phonology), meaning of sentences (semantics), and emotional context (pragmatics), while important components of language, do not pertain directly to syntax. Thus, the focus on the organization of words into coherent utterances is what makes the correct answer particularly relevant to the definition of syntax.
