The Naibbe cipher

[MarcoP]

I vaguely remember that in the Voynich Manuscript there is the tendency of clustering for short and long words, as opposed to natural languages. So, a short word is more likely to follow another short word in the Voynich MS and long words are more likely to be followed by more long words. Was there a paper that described this behavior?

It's mentioned in "Gibberish after all?" Gaskell and Bowern, Malta conference.

A notable feature of the VMS that has to our knowledge only been discussed by one other publication
[20] is positive autocorrelation of word lengths. Word lengths in most meaningful texts are negatively
autocorrelated: that is, long words tend to be interspersed with short words (long-short-long-short). By
contrast, the VMS exhibits positive autocorrelation (long-long-short-short). Positive autocorrelation is
only observed in a limited number of natural languages, but is common in gibberish (Figure 3).
