geoffreycaveney's Judaeo-Greek theory

[-JKP-]

Geoffrey: Voynich [d] is a critical letter. I understand JKP's concern about the status of this character as either a vowel or a consonant, but in fact this also arises naturally from Greek and Hebrew phonology....

It was actually less about that (which is why I used the example of the letter "y" in English, which can be both consonant and vowel) than it was about the degrees of freedom increasing rather substantially when transliterating the VMS characters.

If

1. the vowels can be substituted to a significant extent AND
   
2. you have a character that can function as both a consonant and a vowel AND
   
3. you add vowels to the end as needed...
   

you end up with a system in which there is so much latitude, that it's difficult to assess whether the tokens are being translated or created to suit the language at hand (whether it were Judaeo-Greek or another language wouldn't matter). I can get a lot of words and phrases out of VMS tokens using only number 1.
