Here's why:
* Diction refers to the author's choice of words.
* Words carry connotations - implied meanings beyond their literal definitions. These connotations can be positive, negative, formal, informal, humorous, serious, etc.
* The choice of words directly shapes the reader's understanding of the author's perspective and the overall tone of the piece.
For example:
* "She walked briskly down the street" suggests a sense of purpose and energy.
* "She trudged wearily down the street" suggests fatigue and disappointment.
Other literary elements can also contribute to tone, but diction is the most direct and impactful:
* Imagery: Vivid descriptions can evoke feelings, but they often rely on carefully chosen words.
* Figurative language: Similes, metaphors, and personification can add layers of meaning, but their impact is still rooted in the specific words used.
* Syntax: Sentence structure can influence pacing and emphasis, but ultimately, the chosen words determine the tone.
In short, diction is the foundation of tone. It's the author's voice that directly reveals their attitude towards the subject matter.
