Here's a breakdown:
Didactic: This means the fable is intended to teach a lesson or moral. The tone is often serious and straightforward, emphasizing the importance of the message. Think of Aesop's fables, where the animals are used to illustrate human failings or virtues.
Whimsical: Fables often feature fantastical elements like talking animals, magical objects, or fantastical settings. This can create a lighthearted and playful tone, making the lesson easier to swallow.
Other possible tones:
* Humorous: Some fables use humor to get their point across, employing witty dialogue or absurd situations.
* Satirical: Fables can use allegory to critique societal norms or powerful individuals, leading to a critical and ironic tone.
* Somber: While not as common, some fables deal with serious themes like death or loss, resulting in a melancholy or reflective tone.
Overall:
Fables tend to be accessible to a wide audience, employing simple language and engaging narratives. Their tone is often a blend of seriousness and playfulness, making them both entertaining and thought-provoking.
