The only free rafsi that could be assigned to a gismu that doesn't have any 3-letter rafsi is bod, for brodi (or brodo or brodu, theoretically).
hey, gotta save some rafsi for future expansion! --jay
Furthermore, it is already too nearly the case that anything with the
right lujvo tarmi actually does mean something. Having lots of unused
rafsi (and these are only the usable-but-unused ones; there are plenty
of rafsi like xox or zuz that just don't fit any gismu at all)
makes for better separation, just as banning gicmu and gisnu
keeps gismu better separated. So the above list is not a Bad
Thing.
I used some rafsi be noda in the first verse of Jabberwocky. --phma
