The Constructed Language Hypothesis

[Mark Knowles]

Is it possible to do a word-by-word substitution of the Voynich MS and come up with a meaningful text?

I see more reasons why the answer should be "no"  rather than "yes".

If it is "no", then we cannot create a dictionary of Voynichese to some known language.
A constructed language is most easily conceived in the form of a dictionary.

If it is "no", then also all types of ciphers are excluded, even the more complicated diplomatic ones.

Essentially all past proposed meaningful solutions assume that some form of dictionary should exist.

Do you count the presence of null text within your idea of a meaningful solution?
