Character entropy of Voynichese

[Torsten]

Really, there is no way of escaping the conclusion that the low entropy is simply an intrinsic part of the content, not the result of some "cipher mechanism".  The most likely explanation for that is that the VMS is written in a language which has low entropy, i.e. that has a relatively rigid phonotactic structure.  From that point of view, there is nothing "anomalously low" about the entropy at all, since there exist languages with lower entropy, i.e. with a more rigid phonotactic structure than we find in the VMS text.

The weak word order can only mean that the words are not ordered by a grammar as we know for natural languages. Therefore you would have to assume a language without grammar.
