@elilla So my impression of the relative sanity of orthographic systems is: Latin > French > English > Irish. And the Romans colonized the French colonized the English colonized the Irish. So maybe each time somewhat gets colonized they get worse at spelling.
(Probably Irish is actually more sane than English if you know it, but whenever I read an Irish word and then hear it pronounced the pronunciation and spelling seem to have hardly any connection at all. (Actually, I feel that way with Polish too. But Poland has been colonized a bunch of times too so maybe that validates the theory.))
