Which term refers to the attitude expressed by the writer in a document?

The term that refers to the attitude expressed by the writer in a document is tone. Tone encompasses the emotional quality or mood conveyed through the writer's word choice, sentence structure, and overall writing style. It reflects how the writer feels about the subject matter or the audience and can significantly influence how the reader perceives the message. For example, a formal tone might convey professionalism, while a casual tone could create a friendly or approachable atmosphere.

While style is related to the manner of writing, including vocabulary and sentence structure, it does not specifically convey the writer's attitude. Voice refers to a unique form of expression that reflects the writer's individuality but is distinct from the emotional nuance of tone. Perspective, on the other hand, relates to the writer's viewpoint or position on a subject rather than the emotional attitude expressed in their writing. Thus, identifying tone accurately pinpoints the writer's attitude, making it the correct answer.
