Speculative fraud hypothesis

[Jorge_Stolfi]

As far as I can tell, for the self citation you only require a couple rules:
Create new words by either:
1) taking a previous word and changing a glyph to a similar glyph
2) add a prefix from a list of prefixes if it isn't in the word
3) concatenate existing words

These rules do not seem enough to explain the rather complex structure of the VMS words, and the irregularities in word and next-word distributions.  Unless one starts with a seed text that is, say, 10'000 words long, with the proper word structure and frequency irregularities...

The concatenation of two Voynichese words is generally not a valid Voynichese word, unless the first one happens to be a prefix that is empty in the second one.  In particular, there are practically no words with two or more gallows (and the handful of words that do occur may be just cases of omitted word space).

All the best, --jorge
