Fiction in a sentence means it contains elements that aren't real. For example, if it talks about magical creatures or events that couldn't happen in reality, that's fiction. It's a departure from the truth to create an imaginative or entertaining narrative.

Engaging sentences in fiction often play with the reader's emotions. They might create a feeling of joy, sadness, or suspense. By using powerful imagery, like describing a beautiful sunset or a spooky old house, the sentence can make the reader feel more involved in the story. Moreover, if the sentence has a unique voice, whether it's a character's voice or the author's narrative voice, it can be very engaging. For example, a character with a humorous or sarcastic voice can make even a simple sentence interesting.
You can also play with language and use unique phrases. For instance, 'The wind whispered secrets through the tangled branches, as if the trees themselves were gossiping.' This gives a sense of mystery and makes the sentence more interesting for fiction.
Character is important. A sentence might introduce a character's action like 'John ran through the crowded street, his eyes wild with determination.' Here we get a sense of who John is and what he's doing.
Well, a non-fiction sentence typically conveys objective and verifiable details. It could describe historical events, scientific facts, or personal experiences accurately without fictional elements.
