Why and how the text could be Bavarian

[JoJo_Jost]

After further examining the cipher and developing one myself, I have a different theory

Do you consider now Voynichese a cipher?
You know, there is a big difference between a language written phonetically with custom letters and a cipher.
A cipher can completely change the nature of the text while a custom script shouldn't.

Yes, my thesis is that VMS is an absorption cipher of a Bairish text.

The analysis of Bairish texts is important because the simple ciphers used around 1430 do not alter the text as much as  more complex ciphers would do. In this respect, the underlying text should already exhibit characteristics that make an absorption cipher possible.
