ozone ozones ozoning ozoned

Etymology

From German Ozon, coined 1840 by Christian Friedrich Schönbein, from Ancient Greek ὄζον (ózon), neuter participle of ὄζω (ózō, “I smell”), in reference to its pungent odour. The “fresh air” sense is from an erroneous former belief that seaweed contains and releases ozone.
