geoffreycaveney's Judaeo-Greek theory

[MarcoP]

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.

I understand the concern. It is a valid concern with any ambiguous writing system. But your 3 points would also be valid to challenge the legitimacy of the Judaeo-Greek script itself! All 3 criteria apply to Judaeo-Greek written in the Hebrew script,

The fact that your claims about Judaeo-Greek come without examples from actual Judaeo-Greek sources (carefully transcribed, grammatically analyzed and translated) suggests  that you have never read a Judaeo-Greek text. I find you claims unreliable.
