An explanation of low entropy?

[Koen G]

The word length and entropy are not as unusual as one might think.
It is still within the normal range.

Could you point out a similar string in Voynichese? You make a good point that things like this can lead to paragraphs with low word entropy and semi-reduplication. The string is something like "(und) vo(n) dem/der....". However, one crucial element in these strings is an alternation between the low entropy bit and a high-entropy noun. 

"von den vier elementen, von der erden, von dem lufft, von dem wasser, von dem für" 

There's almost a cadence to the entropy here: low low high, low low high. And most importantly, we immediately see a pattern, that "von de(n/m/r)" performs a formulaic function. Aren't such phrases famously absent from Voynichese?
