PLOT HOLE DEFINITION
In fiction, a plot hole, plothole, or plot error is a gap or inconsistency in a storyline that goes against the flow of logic established by the story's plot. Plot holes are usually created unintentionally, often as a result of editing or the writers simply forgetting that a new event would contradict previous events.
In other words, it's a mistake made by the writer either based on logic, the rules of the story world, or in the characterization. Say your protagonist has an allergic reaction to peanuts and then later eats peanuts with no reaction β that's a plot hole.
