'metalize' originates from the word 'metal,' which comes from the Latin word 'metallum,' meaning 'mine, quarry, metal.'

'metallum' transformed into the Old French word 'metal,' and eventually became the modern English word 'metal' through Middle English.

Initially, it meant 'to mine or extract metal,' but over time it evolved into its current meaning of 'to coat or impregnate with metal.'
