Another link with Roman numerals?

[Koen G]

Right, I agree that word-final flourishes should be considered as a wider phenomenon, of which the use in Roman numerals is but one example. I find them extra intresting though, since like Voynichese, Roman numerals tend to sort glyphs in a specific order. This is especially true if you avoid subtractive notation (so write IIII instead of IV).

If I give you, sorted alphabetically, six different glyphs from a Roman numeral, you can reconstruct the "word" I took them from (assuming additive notation):
CDILVX --> DCLXVI
If I give you six different EVA glyphs, chances are you will be able to reconstruct the "word" I took them from by putting them in the right order as well:
ainoqt -> qotain


None of this explains the behavior of [y] though, since apart from mostly occuring at the final position, it is also common word-initially. We cannot say that it behaves like a capital letter, because those tend to be limited to the first position. It also doesn't seem to function as a disambiguator - in words like [ytchor] and [ytaiin], what is there to distinguish?
