There are things that can be described in numerous ways, but the description still means the same thing.
Is there a word or phrase that encapsulates such things, or the property about the things that allows such interchanging of words?
For example, the situation that brought this to mind was being drunk. You can pretty much add ed to any noun (or use a past participle) and it means drunk:
I am totally: fucked, bollocked, badgered, squirrelled, blasted, wasted, coloned, trousered, wankered, cabbaged, waxed, mashed, etc.
(Yes, some of those aren't in common use, but that is my point, you would still be understood.)
So the word or phrase I'm looking for would decribe the property or category that "being drunk" falls into that means it can be described in such a variety of ways.
