polluter
UK: pəˈluːtə | US: pəˈluːtər
n. a person, company, or entity that contaminates the environment, especially by releasing harmful substances.
The word "polluter" traces back to the Latin verb polluere ("to soil, defile"), which entered Middle English via Old French polluir. The suffix "-er" was added in English to form an agent noun, creating a term for an entity responsible for pollution. The logic is straightforward: "pollut-" (action of contaminating) + "-er" (the doer) = "one who contaminates."
