Why and how the text could be Bavarian

[JoJo_Jost]

In order to explain the word structure in the Voynich MS text, you need to rely on such major changes to a source text, that the differences between German, Bavarian, and in fact other European source languages fade in comparison.
The low conditional entropy (or the bigram entropy) of the Voynich text is a consequence of this word structure, and it is far too anomalous to be explained by small things like swapping characters or removing distinctions between p and b (and a few more).

Yes, that may well be the case – I have realized how unusual the VMS is.

At this point, one could actually drop out, because more complex ciphers (such as, in my opinion, the Naibbe cipher) would be anachronistic for this period. This dramatically increases the likelihood of a hoax.

Or you could take a different approach. Thanks to Stolfi, I realised that it might make sense to find a language that is almost monosyllabic. Bavarian is probably the only language in Europe that fits this description reasonably well. And that's quite interesting because the marginalia are probably in Bavarian, and the writers of the marginalia may even have been able to write Voynich (or imagined they could ).

Is this a coincidence? Yes, it could be, but it actually fits too perfectly to really be a coincidence. It is so unusual that it MUST be investigated further. In my opinion. I just don't know if I'm the right person for this job, but I speak German and understand some dialects, and as a journalist and writer with nearly 40 years of experience, I know my language reasonably well and have an advanced understanding of it.

So, in step 2, I want to check whether a cipher that fits the early 15th century can produce some of the anomalies of the VMS, for example the low entropy (this is not yet a solution, but a plausibility check).

And I think I'm at least heading in that direction. It'll just take a little more time.
