Okay but even as a native hungarian i have to say "sz" is just insane. Polish is so much more logical with "s" making the non-shushing sound and "sz" making the shushing sound. Also "gy" is not very logical as it should be "dy" but when the italians first tried to write hungarian down they used g cause in italian g can sound like "gy" in many cases. And then lastly "ly" is just utterly useless, it used to represent a seperate sound with some words contrasting them "boj" vs "boly" was a thing from what i could find, but the dialect modern standard hungarian was based on did not have this distinction so they just used "j" everywhere but kept "ly" where there wasnt a word with "j" that was spelt the same otherwise. This means modern day hungarian speakers in for example slovakia will say all "ly" as the sound for "ly" and "j" will be a mix between the two. As for features they couldve written down but didnt, in both of the dialects i grew up with(family from szeged, but grew up in the north west) there are two "e" sounds, sometimes written as "e" and "ë" when the distinction is wanted. Szeged is an example itself with it being possible to write it as "Szëged" because in the dialect there its pronounced as "Szöged". On the other hand where i grew up its "Szegæd" where "æ" is pronounced kind of like "a" in english "ash". Point is hungarian spelling is very much not logical, there are even more examples like "lesz" actually being pronounced with long sz usually so "lessz" would be more accurate, "is" and "se" being clitics like "-e", and there actually being a long and short "e" distinct from "é" in some words technically making them phonemes like in "ere"(his vein) pronounced "ere" vs erre(this way) pronounced as "eere" or more often written as "ēre". So yeah many holes tho still a thousand times better than most european languages spelling.
