Petrasti's Celtic Theory

[Petrasti]

I'd like to give you a few examples, but for that we'll have to leave the EVA alphabet. If you consider EVA an unquestionable basis for translating the Voynich, then things will get difficult.

Let's take the word "ban" dain for white
we find in the manuscript ban as follow:

oban odain                           
aban ydain
ghoban c+hodain
goban chodain                
kaban kadain
aPoban apodain
gban chdain
qoban qodain
Tban tdain 

the word kam for jagged and serrated
we find the word as:

akam ykaiin
kokam kokaiin
gokam chokaiin
okam okaiin
hkam skaiin
qokam qokaiin
Tgkam tchkaiin
orkam olkaiin
rkam lkaiin
ghakam c+hykaiin

the word gob chod berry, we fill find as follow:

chod and c+hod
tgob tchod
kgob kchod
chkgob chkchod
qokgob qokchod
qotgob qotchod
orgob olchod
otgob otchod

the same symstem takes place with gol for flower chor

chor and c+hor
tgol tchor 
bgol dchor
agol ychor
ogol ochor
qokgol qokchor
pgol pchor 
kgol kchor 
otgol otchor 
okgol okchor 
hgol schor
gogol chochor

the word gor chol for leaf

chol and c+hol
agor ychol
ogor ochol
qogor qochol
qokgor qokchol
qotgor qotchol
bgor dchol
hgor schol
kgor kchol
tgor tchol
pgor pchol
otgor otchol

I consider the letters k, p, t, f, b, g, a, o, qo, and h to be pre-sounds, as they can be consistently assigned to words as initial sounds.

We also have a sound change: g ch and gh c+h. 
Around 88% of the words that begin with gh c+h also begin with g ch

Also the base words like e.g. gol chor that begin with g ch exist both with the gallow signs before the g and with the gallow sign integrated into the g (tch and cth). I haven't yet checked their frequency. but there seems to be a regularity
