Voynichese is a numeric cipher?

[ololololo]

that ist normal... u find this in other languages, too

Which ones?
I’ve sometimes come across examples in languages where one word ends with the same letter that the next one starts with (e.g., “eat toffee”). However, this feature is characteristic of almost the entire Voynich manuscript.
The only similar linguistic phenomenon I know of is tongue twisters. But VMS isn’t a set of tongue‑twisters, right?
