I can't for the life of me figure out how to pronounce "A dinna ken".
I also think the American pronunciation of aluminium is weird. Are there any words that just, in different countries, you hate the rewording or re pronunciation?
My friend in Australia hates how Americans call lifts elevators, etc. Same with the zee/zed for the letter z thing.
ETA: I also cannot pronounce "rural" to save.my.life. (I have trouble with a lot of words, but that's one of them.)
