Zynemorgs

a partial realization

"Zynemorg", a typographical symbol used to represent the various degrees of belief an author has in a word or statement.

Lojban using zbalermorna is one way i've tried (note that there are several proposed alphabets; my own preference is Apollonian).

In my conlang Glaugnea there is a 4-value logic. (Its alphabet renders these prefixes somewhat unwieldy.)

Somewhat further elucidation of what i was trying to do with that logic.
