Or, rafsi not in the official lists (some are mention is such official things as the book).
- zi'o zil is in the gismu list, just not the rafsi list
- kibro kibro is an experimental gismu
I suggest these for hex digits (mi'e rab.spir):
- Or just say that xem is a rafsi for xei or rei, whichever you use.
- No other cmavo has a rafsi whose only similarity to it is the vowel.
