KK: /æntiˈpɒljuːʃən/
Designed to reduce or prevent pollution in the environment.
The city implemented antipollution measures to improve air quality.
Antipollution is formed from "anti-" (meaning against) and "pollutio" (from Latin, meaning pollution or defilement). The word refers to actions or measures that are against pollution or aimed at preventing it.
Think of 'anti-' meaning against, and 'pollutio' referring to pollution — so antipollution means actions taken against pollution.
