What aspect of language deals with how words are organized or ordered?

The aspect of language that deals with how words are organized or ordered is referred to as syntax rules. Syntax involves the structure of sentences and the arrangement of words to create meaning. It encompasses the rules that govern how sentences are formed and how different parts of speech—such as nouns, verbs, adjectives, etc.—are combined to convey specific ideas. Understanding syntax is crucial for effective communication, as the meaning of a sentence can change significantly with variations in word order.

Phonological rules pertain to sound patterns in speech, pragmatic rules focus on the context of language use, and idiosyncratic rules relate to unique or peculiar language use by individuals. Each of these aspects plays a role in language but does not specifically address the organization or ordering of words in sentences, which is strictly the domain of syntax.
