Word Origin & History

aluminum
1812, coined by English chemist Sir Humphry Davy (1778-1829), from L. alumen "alum" (see alum). Davy originally called it alumium (1808), then amended this to aluminum, which remains the U.S. word, but British editors in 1812 further amended it to aluminium, the modern preferred
British form, to better harmonize with other element names (sodium, potassium, etc.).
"Aluminium, for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound." ["Quarterly Review," 1812]
