bu'o'e BYBOI experimental cmavo

elliptical/unspecified/vague letteral/symbol

Has use in mekso at the least; in this context, it might subsume xo'e (but see: xo'e'o'e). It also may be useful in spelling, initialisms, etc. If used as a pro-sumti (as other letters are), it means zo'e but only for reasonable or previously specified letterals assignments.

In notes:
