George Orwell is an exemplar in so many ways: a famed truth-teller who made things up, a left-winger who mocked left-wingers, an author of a much-misunderstood novel (see “Objects of the class ‘Sherlock Holmes,’”) probably a few dozen more.
But here I’m talking about Orwell’s name being used as an adjective. More specifically, “Orwellian” being used to refer specifically to the sort of doublespeak that Orwell deplored. When someone says something is Orwellian, they mean it’s something that Orwell would’ve hated.
Another example: Kafkaesque. A Kafkaesque world is not something Kafka would’ve wanted.
Just to be clear: I’m not saying there’s anything wrong with referring to doublespeak as Orwellian—the man did write a lot about it! It’s just interesting to think of things named after people who hated them.
