The incompatibility of Voynichese with natural human language

[nickpelling]

On the original topic of this thread, I can only pose this rhetorical question: is the Voynich text compatible with a medieval cipher?

Taking the rhetorical bait :-) , I'd say that Voynichese is incompatible with what cryptological historians might classify as "mainstream" medieval ciphers, but for broadly the same reasons that make it incompatible with just about every natural language under the sun.

Furthermore, even though Currier A and Currier B have many language-like facets (for want of a better word) in common, I'd be surprised if I was the only researcher who finds that the two read immensely differently. The A/B differences are so fundamental and structural that they surely cannot be merely artifacts of a change in vocabulary.

Hence I'd say that what we see in Voynichese is not only incompatible with natural human language, it is incompatible with natural human language twice over.
