Your briefs will be tighter, smoother, and easier to read. I have altered Orwell s rule here just a bit. But as altered, it is ideal advice for brief writers. Write and a level that is easy to understand. I hope so.
Judges think so, too.
So stop using pompous words, jargon words, or unnecessarily formal words because you believe they are part of the profession or are terms of art. To take this idea further, let me suggest something a bit outlandish. I have made this principle into a personal challenge. Whenever I see a long, formal, archaic, pompous, or lawyers-only word, I ask myself if I can banish that word from my vocabulary. Then I never use that word again.
