Wow! This is just what I often joke about to my friends. I write in such heavy cursives that when I write words like Minimum or Aluminium, they become hard to read for anyone else.
Sounds like the British guy who discovered it settled on the spelling without the extra i
A January 1811 summary of one of Davy's lectures at the Royal Society mentioned the name aluminium as a possibility. The next year, Davy published a chemistry textbook in which he used the spelling aluminum.
It was called aluminum for a long time universally. Everyone else changed to aluminium when it was discovered to be an element and was renamed to meet the naming scheme of the time
America kept the old word. I'm half surprised America doesn't call gold aurium
Im saying that it's not a typo if the creator of a word spells it a certain way multiple times in a book. They clearly meant to spell it that way when they were writing the book.
