Syllabification

[Sam G]

This is a verbose cipher.  Like I said above, it's basically the only possibility for generating language-like (and low entropy) ciphertext.  The problem with it is that if such a cipher were used, then we should see many repeated sequences of several words in the ciphertext (as every instance of the same plaintext word would yield the same sequence of ciphertext words), and we don't see this in the VMS.  So it is not possible that the VMS is written with a verbose cipher.
