Which term refers to the arrangement and organization of sentences in writing?

The term that refers to the arrangement and organization of sentences in writing is syntax. Syntax specifically deals with how words and phrases are arranged to create well-formed sentences, which can significantly impact the meaning and clarity of the writing. Proper syntax allows writers to convey their thoughts effectively, engaging the reader and guiding them through the text.

Understanding syntax is crucial because it affects tone and pacing, which can alter a reader's perception and interpretation of the content. For example, varying sentence lengths and structures can create rhythm and emphasis, both of which are essential elements in effective communication.

The other terms mentioned do not pertain to the structure of sentences. Theme refers to the central topic or underlying message of a work. Thesis is a statement that a writer puts forward as a premise to be maintained or proved. Style encompasses the unique manner in which a writer expresses their thoughts, including diction and tone, but it does not specifically address sentence arrangement.
