@Arden The root is alumina, (in contrast with magnesia) and the correct ending is given by dropping the "a" and adding "um". This has been followed in Platinum (from platina) etc. Someone overrode Davy's spelling (aluminum) and that has, unfortunately stuck with those lacking the understanding of Latin endings.
