Why the Voynich Manuscript Might Not Be a Real Language

[ReneZ]

This process has the result that the most frequent words of the language will tend to get the smallest code numbers.  if the codes are written in a Roman-like scheme as described in that page, the most common words will tend to get shorter codes-- an optimization seen in natural languages and the VMS.

Exactly, but this scheme would not result in words differing only on the left-hand side to appear near each other frequently. That's the problem of the both-endian nature of the words, and the resulting unlikelihood that the words follow some enumeration scheme.

(Of course, it is still possible to imagine ways around that).
