But is there any reason why masses cannot have a most important
member? Does this lead to confusion? The point of making
distinctions is to avoid ambiguity. Otherwise it is like having
gender for nouns, we could do it, but what for? At least Adam's
example with {simxu} pointed out an actual difference, but is
there a difference in using {ralju} with sets or with masses?

I'll give it a shot. Let's use {girzu} for "club", and
{mulgirzu} for "final club". This should work:
ca'e ro da poi girzu cu mulgirzu
I define: Every club is a final club.
I think that is the only way that what you called a
definition can really define final clubs.
