The pragmatic nature of the script

[Koen G]

It seems highly relevant that the Voynich script looks fluid when writing its "own language":

torchey otaiin chary oteory otal

but not when writing anything else:

the quick brown fox etc

Good point Rene so called Zandbergen

Exactly! And I think we can also say why this is the case. If we write it normally using EVA, it quickly becomes too busy. Strokes stick out everywhere and look out of place.

Now on the one hand, we've gotten used to the "flow" of Voynichese and we notice immediately when something is up. When typing in English, we create all kinds of sequences which are just impossible in Voynichese.

But on the other hand, it can't just be that. If I type a bunch of nonsense in a normal font, the font still looks fine. "oror quookedy cheol" sounds like nonsense, but the letters themselves flow just fine. So the point is, which you likely mean, that there is such a flow to Voynichese. 

One might say that this flow is in the "language", but I personally don't think that's the case. I think the flow is rather in the script. Too many glyphs look like versions of another glyph with an extra stroke or other embellishment. A flourish. Those usually occupy specific places in the word, which is why you get some of Voynichese's unusual statistics. 

And if you use anything else than Voynichese for the input of an EVA font, the flourished versions get all over the place, which looks weird.
