Prose is when people write stories, letters, or even emails using normal words and sentences, instead of writing them in poems or songs. It's like talking with someone in writing. If you think of a poem like a fancy cake with lots of layers, frosting, and decorations, prose is like a simple but delicious sandwich that you can eat every day. Just like how you use normal words and sentences to talk to your friends, authors use prose to tell their story in a way that everyone can understand without having to think too much about the words they're reading.
