Latin is obviously the best, The Romans made it themselves!
Edit:
But the written Polish written language is also very easy to understand.
For example i'm only putting down the difference from Polish to English:
A = a in "half"
o = o in "November"
U, Ó = oo as in "food"
e = e as in "get"
i = ee as in "feet"
Y = like I in "bit"
Ą = in the middle of a word, sounds like "On" or "om"
Ę = in the middle of a word, sounds like "en" or "em"
Ę = at the end of a word, sounds like e in "self"
Ą = at the end of a word, sounds like "on" as in "Bon Appetit"
Now for Consonants:
Again only the ones that are different from the english version.
C = sounds like "TS" in "cats"
Cz = sounds like CH in "church"
Ć, Ci = like "T" in "nature" but a bit softer.
Ch, h = like "H" in "Ham"
Dz = Ds in "ads"
DŹ, Dzi = like J in "jeep"
DŻ = like dg in "dodge"
j = like Y in "yes"
Ł = like W in "was"
sz = like SH in "shake"
Ś, Si = like S in "sure"
w = like V in "very"
Ź, ZI = Z in "Zero" but softer.
Ż, rz = like s in "measure"
In the Polish language, There is no Q, X or V.
As long as you learn what i just told you, you can say read anything in Polish. Really it's that easy.
And unlike in English, there is no/barely any exceptions, where in english there's billions of exceptions.
