Etymology

The word "benign" traces back to Latin benignus ("kind, generous"), combining bene ("well") + -gnus (a suffix denoting innate quality). It originally described people with a gentle nature, later extending to medical contexts (e.g., non-threatening tumors) and favorable conditions. The morpheme ben persists in English (e.g., "benefit," "benevolent"), while -ign is rare but echoes in words like "malign" (its antonym, from malus "bad").
