Voynich through Phonetic Irish

[rikforto]

So, what you're doing is not in good faith. It's rude.

I can't agree. It is straightforward, yes, and it does simplify, but it's designed to highlight a point and it does a reasonably good job. Overall I see little difference between your solution and rikforto's mockup, other than yours is much more complex and evolved.

Can you use my methodology and see what you produce?

No, even though I tried. One of the most common words in the MS is chol. According to the table you posted it's r??, only the first glyph has a single unique mapping, there is no way to identify which word this could be. Another very common word is chedy. It's r?d[in], again it's absolutely unclear what this should map to.

If you wish to demonstrate your methodology, here are some of the most common words in the MS: chedy, Shedy, chol, chey, cheol, Shey, chor, dar. Each one of these appears more than a hundred times in the manuscript. If the manuscript is a phonetic representation of a language, each of these should map to some very common word. It's possible that some of them have several meanings, but at least one of the meanings should be a frequent word. What are these 8 common words, could you list them?

For the sake of comparison, here is what I get based on the notes I posted, which I've never quite gotten a straight answer on whether or not I understand the transliteration, but it's where I'm at. Because I agree there is no record of what e ought to be, these results are not wholly indeptendent because I peaked at the translations given to get "i", but this is the problem with not having a complete system.
chedy: ridhin (compare rith)
Shedy: bhidhin (compare bréidín; given l is a fada I am quite confused where the two are coming from)
chol: ra' (matches rá)
chey: riin (compare rinn)
cheol: ria' (compare reann)
Shey: bhiin (compare reann? ré? One of us has quite lost the plot, I think?)
chor: ragh, raigh, or rag ("r" is one of the more problematic letters in my notes, and I think this has something to do with how the relevant sound is rendered in Irish spelling; regardless, compare ráig and note the absence of a l to give fada)
dar: dogh, etc. (compare deoch)

So while I'm able to get in the ballpark for most, and I suspect some of the divergences are down to the system not being explicitly linked to the intricacies of Irish spelling, I still see quite a few arbitrary choices surfacing, especially unexplained fada and shifting vowels. Shey may need a second look. This is before I begin playing around with the dictionary, but before I do that, we need to all get on the same page about how to read what's actually in the manuscript.
