Okay kiddo, so do you remember learning about sentences and how they have to have a subject and a predicate? Well, sometimes people like to leave out some words in the sentence on purpose, and that's called anapodoton.
It's like if I said "Had pancakes for breakfast, not eggs." Do you see how I left out the subject "I" in the second part of the sentence? That's anapodoton!
People use anapodoton to be more creative with their writing and to make it more interesting to read. It can make the reader feel like they have to fill in the missing words themselves, which can be fun!
