Some letters aren't letters

[ReneZ]

The character y is interesting in yet another way.
It is very frequent, and it seems to behave almost normally.

However, when one makes a list of the vocabulary of Voynichese words, one find that more than one third of all words ends with a y.

I just cannot see how any natural language would behave in this way.

Linguistically / phonetically I also don't see any way out here, but I am not the expert.

It almost seems as if it has no further function beside saying 'end of word'.

Or, tongue firmly placed in cheek:

-y    -> default word ending
-r    -> word ending (variant 2)
-iin  -> word ending (variant 3)
-l    -> word ending (variant 4)

This of course hints at an indication of tones, for a tonal language, but I am fairly confident (without knowing for certain) that this would be anachronistic.

In any case, for me y is another character that cannot be mapped to a letter.
