Oddly - according to many linguists, which is a really odd job to have, you Americans have a purer form of the original language, say from Shakespeare’s time. Your pronunciation, at least. Except for aluminium - that’s just barbaric the way you butcher an innocent word :)
Yeah, that’s what I’ve heard — that we sound like what English English sounded like before the great vowel shift happened. Which is kind of cool actually.
As for aluminum, don’t we Yanks at least get some credit for our earnest phoneticism? You guys add syllables that aren’t even there for crying out loud. On the other hand, when you invent a language I guess you earn the right to take some license with it. And I must admit the result in the case of aluminum is quite charming with its extra convolutions.
