And even more tellingly, there's so many words in english where native speakers don't even agree how it's pronounced since there's no consistent pattern. Just depends how each person first heard it and got used to it.
In finnish pronounciation and spelling are 1:1, competely predictable with no exceptions. The english language game of a spelling bee would be extremely boring in finnish as there are no trick spellings. It's always written the way it is said.
As an English person, there are parts of my own country where it will take me a bit of time to get my ear tuned to the local accent and dialect (just this evening my wife's mother, from south yorkshire, used a word I'd never heard). But I was under the impression this is pretty common, at least across Europe. I've heard French people complaining about how people from some other part of France speak, the same for Germany. Is Finnish unusual in having a more homogeneous pronunciation?
I'm not being defensive or anything, this is a genuine question. As someone who struggled to spell at school I'm well aware of what a mess English is.
AFAICS, I'd say yes, it is.
There are some dialects (way up north, and in the East) where stuff is pronounced differently, but that's so hilariously different that I think speakers of those dialects are themselves fully aware that the way they pronounce stuff, it oughta be spelled differently. And conversely, what with only the "official" spelling being taught in school, they automatically learn the "correct" nationwide pronunciation from that -- thanks to the "everything is spelled as it's pronounced, and vice versa" phenomenon.
Overall it feels like a simple language though, none of the annoying stuff such as gendered nouns and declension.
