anti-pollution

The word is a modern compound formed in English during the 20th century, directly combining two established morphemes. The prefix "anti-," with its ancient Greek lineage meaning "against," is attached to the noun "pollution," which originates from the Latin verb for defiling or making filthy. This construction follows a transparent and logical pattern in English word formation, where "anti-" is prefixed to a noun to create an adjective describing something intended to counteract that noun. Thus, "anti-pollution" literally means "against pollution," describing measures, technologies, or laws designed to prevent or reduce environmental contamination.

Structure: anti (against) + pollution (contamination) - anti: From Greek, via Latin and French. A prefix meaning "against," "opposite of," or "preventative of." - pollution: From Latin pollutionem (defilement), from the root polluere (to soil, defile). In English, it functions as a noun meaning the presence of harmful substances in the environment.
