Theory: perhaps the letters do not have phonemic content?

[epidemic7]

Such a "semantic" system is too difficult to implement, read, and practice. This is incredibly expensive on a VMS scale.
Of course, if you're a beginner, this may not be possible, but I would like to see examples of words from the manuscript that could match or resemble your pattern.
As I understand it, you consider Voynichese to be a philosophical language. Well, this hypothesis is quite vague, but it's also interesting.
However, this idea may be feasible as a cipher, but not as a separate semantic system...

I will admit that the semantic aspect of the script is an unfounded idea in retrospect, and I agree it is definitely more feasible as a pure cipher/shorthand. A good test of the semantic theory would probably be trying to find patterns in, say, the "labels" in the Herbal section, but looking at them now, I don't think there is a correspondence between the letters and any category of thing one can find. "Semantic" letters are probably just a bust.
