Root Explanation

Aerugo is derived from the Latin word "aerugo" (meaning green or bluish-green), which refers to the green rust that forms on copper and bronze. The term is related to the Greek word "aerugos" (meaning greenish), which also describes the color associated with corrosion of metals. Thus, "aerugo" specifically denotes the green patina that develops on copper surfaces due to oxidation.

Memory Tip

Imagine the green color of rust on copper — that's what 'aerugo' refers to, as it means the greenish corrosion that forms on metals.
