Why and how the text could be Bavarian

[Rafal]

As already written here, I even suspect that it could be incredibly difficult to decipher VMS, precisely because of the many possibilities and variants of Bavarian, including, among many others, those pointed out by Stefan here

That's fair said.

If you ever try to read Voynichese as Bavarian remember that the most common words should be simple words like "and", "or", "with", "by" and so on.
Also Bavarian should have some kind of der/die/das word like standard German, am I right?
Unfortunately we don't have good candidates for such words.

And remember that 50% of Voynichese words end with "9". You won't find any similar letter in Bavarian, I believe.

I have wondered about it once and some possible option could be tricks similar to Pig Latin which I have already mentioned in this thread.
For example in classical Pig Latin 100% of words end with "y"

For words that begin with consonait sounds, these are also known as consonant blends (two letters that make one sound: e.g., black, slack, clown). The initial consonant blend (or two letters) is moved to the end of the word, then "ay" is added, as in the following examples:

• "pig" = "igpay"
  
• "latin" = "atinlay"
  
• "banana" = "ananabay"
  
• "black" = "ackblay"
