There's one thing that Americans And Brits have yet to come to an agreement on- the pronunciation of the word aluminum. British spelling is with an extra “i”, which tends to vex Americans.
But is there more to this disagreement besides an extra “i”?
Looking at the root of this debate we see that Brits (and pretty much everyone besides Americans) spell and pronounce the word with an extra “i” because of a precedent set in 1812 by scientific colleagues of Sir Humphrey Davy, the identifier and namer of the metal.
Davy initially called the metal aluminum, but Davy's colleagues felt that aluminium sounded more classical cool so they pushed for the extra “i”, and this totally metal pronunciation debate was born.
