nonferrous

The word 'nonferrous' is a modern scientific compound formed within English. Its first element is the Latin-derived negative prefix 'non-,' meaning "not." The second element, 'ferrous,' originates from the Latin noun 'ferrum,' meaning "iron," combined with the English adjectival suffix '-ous,' which denotes possession or relation. Thus, the term's literal construction is "not iron-containing," a logical and precise descriptor used primarily in metallurgy and industry to categorize metals and alloys, such as copper, aluminum, or gold, based on the absence of iron.
