Word Origin and History for aluminic

aluminum

n.

1812, coined by English chemist Sir Humphry Davy (1778-1829), from alumina, name given 18c. to aluminum oxide, from Latin 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 metallic 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]
