Which term refers to the arrangement of words in a sentence?

The term that refers to the arrangement of words in a sentence is "syntax." Syntax is a fundamental concept in linguistics and literary studies that deals with how words combine to form phrases, clauses, and sentences. It governs the rules and patterns for sentence construction, allowing for clarity and meaning in communication. Proper syntax helps convey the intended message effectively, shaping the overall style and tone of a piece of writing.

While the other choices like "structure," "grammar," and "format" may relate to language and writing, they do not specifically define the arrangement of words. "Grammar" includes broader aspects such as rules of word use, punctuation, and tense, while "structure" generally refers to the overall organization of a text rather than the specific order of words. "Format" pertains more to the layout or presentation of written work, such as font size and page arrangement, rather than the syntactical arrangement of words in a sentence.
