Animal farm has a simple structure, like most fairy stories. The events are described in chronological order (the order they happen) so the story is easy to follow.
The chronological structure lets the reader see the gradual decline of Animalism. It shows Napoleon taking control by slowly undermining each commandment in turn, until there is nothing left "except a singlecommandment"
The story is cyclical - the end of the novel is very similar to the beginning. Orwell hints at this ending throughout the book, so there is a sense of inevitability about the rebellionsfailure.
Orwell uses the farms name to show the revolutions progress. Under Jones, the farm is called "Manorfarm". When the animals are free from Jones it becomes "AnimalFarm". When Napoleon renames it "TheManorFarm", it shows the revolution has failed.
The final chapter shows the pigs "melting" and changing into men. The other animals can barely distinguish the two.
Narrator uses simple, unemotional language, and only describes what the working animals see. As a result the readers view of the farm is restricted, and you are left to make up your own mind about what's happening.
De attached - The anonymous narrator thoughts are controlled and de attached so that the reader isn't directly influenced, this is important because one of the books themes is the twisting of language.
The story is told from the working animals point of view - this suggests that Orwellsympathises with the working class. For example, the reader is told what "Clover would have said" if she had spoken her thoughts.
Telling the story from more from the working animals point of view shows how naive they are. The reader understands things the animals don't.
Whereas the reader draws conclusions from what the narrator does (or doesn't) say, the animals fail the earn from the events of the novel.
How do the pigs' actions reflect the breakdown of the seven Commandments?
They alter the Commandments to justify their actions
