Voynich text generation

[-JKP-]

...
To have any hope of solving this, I'm going to have to ask for a clarification on the consistency of the character [a] in this cipher:

In the cipher text [a] appears 11 times as part of [ain], 9 times as part of [aiin] (including the endings of all 4 lines!), and 8 times elsewhere without [(i)in] following it.

...

I'm not sure how to answer this without giving too much away. The prevalence of "a" is a linguistic reality in some languages.
