Voynichese is a numeric cipher?

[Radim Dobeš]

At one point, the thought occurred to me that a single word in the Voynich manuscript represents an abugida, or an abugida with an additional symbol.

Could you tell me which word you meant?
Many "aboriginal" languages nowadays use Abugida, for example, Pollard's writing for some Southeast Asian languages. In the context of linguistic theory, this really makes sense...
Anyway, everything is possible

Let me give this example from the Ge'ez language. It is a random selection, just for illustration. What if four words from the Voynich Manuscript correspond to four Ge'ez characters? If this is nonsense, I apologize.
