Voynich through Phonetic Irish

[Doireannjane]

1. I do not have an adjective there. I've used whitish in other sentences and this sentence itself does not position an adjective there where it is, so I break up the word. Fo BHAIN 
I didn't include a word here that was a possibility (not phonetic though. words for qo are fo-, fa, fo or fia-, fo- meaning under and fia- meaning wild). The line under Under Thatch as a possibility is: 
fia-bhán, m. (gs. -áin, pl. ~ta). Untilled lea.

Thank you for clarifying that I need not concern myself with the adjectival form, though I share Davis's concerns about choosing between the two. But even then, there were several moving parts to this question. That still leaves the question of how you interpret that in a long string of nouns, my question 4 under syntax. Please answer it.

Correct 
abhouil - bi

Can you explain how you go from one to the other? I could not find abhouil in Irish conjugation tables or the dictionary. (This is question 3 under the word choices.)

7. From for Olog is the ending/suffix: 

afada

So it is ológá, not ológ?

No it is ológ dhin (or dínn)
