What concept involves the arrangement of words to form grammatically correct sentences?

The concept that involves the arrangement of words to form grammatically correct sentences is syntax. Syntax refers to the set of rules, principles, and processes that govern the structure of sentences in a language, which includes the order of words and the relationships between them. Understanding syntax is essential for constructing coherent and meaningful sentences, as it dictates how different parts of speech—such as nouns, verbs, adjectives, and adverbs—are combined to convey thoughts effectively.

In contrast, morphology deals with the structure of words and their meaningful components (like prefixes and suffixes), while semantics focuses on the meaning of words and phrases. Pragmatics involves the context of language use and the social aspects of communication, such as how context influences interpretation. Each of these concepts plays a crucial role in language, but only syntax specifically addresses the arrangement of words to create grammatically correct sentences.
