* The overall structure of a sentence: This relates to syntax, not diction. For instance, a sentence's subject-verb-object order isn't about diction.
* The emotional impact of a story: While diction can contribute to the emotional impact, it's not the sole determinant. Plot, character development, and imagery also play crucial roles.
* The visual elements of a poem: If the poem has illustrations, they are not part of the diction.
* The length of a paragraph: Paragraph length is a matter of formatting, not diction.
* The overall tone of a speech: Tone can be influenced by diction, but it's a broader concept that encompasses elements beyond word choice.
In essence, a non-example of diction is anything that doesn't directly relate to the specific words used in a piece of writing or speech.
