Thank you! Language, specifically legalese, tries to make precise something that can't ever be. It's why "language prescriptivists" annoy me because it's not even a preference difference it's simply impossible, you can't define any word completely. Worse even if you could your definition is only good for a point in time.

Even simple things like chairs, you can't write down a definition that includes everything that humans consider chairs and excludes everything humans don't consider chairs.
