The Orwell comparisons may seem trite to you, but the fact is that if there's no available word for a thing, it becomes difficult for people at large to discuss it.

Some organisations conclude that if the masses can't name a thing, then it's impossible for anyone to think of it, and that this makes it go away. Personally I think this underestimates individual people's capacity to think up new names for things, and is therefore doomed to failure.
