'aluminous' originates from Latin, specifically the word 'aluminōsus,' where 'alumin-' referred to 'alum' or 'aluminum.'

'aluminōsus' transformed into the French word 'alumineux,' and eventually became the modern English word 'aluminous' through Middle English.

Initially, it meant 'pertaining to alum,' but over time it evolved into its current meaning of 'containing or relating to alumina or aluminum.'
