Answer: The definition of "tone" in literature is the way the author expresses his attitude through his writing. The tone can change very quickly or may remain the same throughout the story. Tone is expressed by your use of syntax, your point of view, your diction, and the level of formality in your writing.
Step-by-step explanation:
Often an author's tone is described by adjectives, such as: cynical, depressed, sympathetic, cheerful, outraged, positive, angry, sarcastic, prayerful, ironic, solemn, vindictive, intense, excited.
