What is the word for words that oppose all the things they describe?

Question

I am looking for a word but I'm not sure if it's a real word or if I just don't know it. I am discussing George Orwell's novel, *1984*, and how the titles oppose all the things they describe. For instance, the "Victory Cigarettes" fall apart and are horrible, not the victor of anything. The "Victory Mansions" are small and crappy apartments. The word "victory" is describing something that is the opposite of victory. It's like a euphemism but instead of using it to lighten the blow, is is completely wrong and opposite of what it really is.

Answer 1

You may be thinking of an antonym. In this case, you could also say that the author is using irony, or that the word used to describe something is the antithesis of what the the thing actually is.
