Voynich through Phonetic Irish

[rikforto]

So there are a few things: d or dh are not distinguished, they’re both represented by infinity sign. But Dh in modern Irish in middle of a word can sound silent or like EE syllable, like in ATHDHEAN it sounds like AH HEE ANN.

Wait, does d represent letters (e.g., Irish alphabetical symbols d or dh) or does it represent the underlying sounds (e.g. IPA /ɣ/, /j/)? I realize there is a correspondence between the two, but are you saying the Voynichnese script is mainly phonetic or orthographic?/j/)
