I am curious, why does "vacuum" have two "u's?" I am aware that it is a Latin-derived-Word, so therefore it was probably pronounced [wakwum], logically. Is this correct? I can understand us English speakers maintaining the original spelling, and then pronouncing it as any of: [vacym~vakym~vacjum~vakjum~vacjʌm], because of our willingness to preserve the original spelling*, but why do other languages maintain the the two "u's" also? Or, because I am unaware of Latin spelling, was it pronounced: [wakuːm] or potentially [wakwuːm].
*for instance, how words that maintained "-tjon (-tion)" like "Nation." We opted to continue to spell them "natjon~nation" for preservation of the original spelling, and keep saying [naˑsjon~nasjon], rather than spelling it "nacion," as some languages opted, to preserve the hint of the words' latin origins.
