Orwell uses dramatic irony by letting readers recognize the pigs’ lies and corruption while many of the animals remain confused, trusting, or too frightened to object. This gap in understanding helps characterize many of the animals in the novella: Napoleon appears as a calculating tyrant, Squealer as a master manipulator, Boxer as tragically loyal, Clover as morally sensitive but powerless, and Benjamin as perceptive but passive.
The early dispute over milk and apples shows this clearly. Squealer tells the animals, “It is for your sake that we drink that milk and eat those apples.” The animals accept the argument because Squealer presents the pigs as self-sacrificing brainworkers, but readers can see that the pigs are already creating privilege for themselves. The irony exposes Squealer’s talent for making selfishness sound like duty, while it also reveals the other animals’ vulnerability to confident language.
Orwell develops the same effect through the altered Commandments. After the executions, Muriel reads that the rule now says, “No animal shall kill any other animal WITHOUT CAUSE.” The animals conclude that the Commandment has not been broken, but readers understand that the law has been changed to excuse Napoleon’s violence. Later, Squealer is found by the barn wall: “Squealer, temporarily stunned, was sprawling beside it, and near at hand there lay a lantern, a paint-brush, and an overturned pot of white paint.” Most animals cannot interpret the scene, but the evidence makes the pigs’ fraud obvious to readers. Benjamin’s reaction deepens his characterization: “None of the animals could form any idea as to what this meant, except old Benjamin, who nodded his muzzle with a knowing air, and seemed to understand, but would say nothing.”
The dramatic irony surrounding Boxer’s character is especially painful. His mottos, “I will work harder!” and “Napoleon is always right,” sound noble to him, but readers see that these beliefs make him easier to exploit. When he is sent away in a van marked for slaughter, his faith in Napoleon becomes tragic rather than admirable.
By the end of the book, the irony becomes visible even to the animals: “The creatures outside looked from pig to man, and from man to pig, and from pig to man again; but already it was impossible to say which was which.” The pattern of misunderstanding reveals how tyranny depends on ignorance, fear, and misplaced loyalty, while also showing how some characters see corruption without finding the courage or language to resist it.
