ozone

See also: ozoné

English

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.

Noun

ozone (uncountable)

1. (inorganic chemistry) An allotrope of oxygen (symbol O₃) having three atoms in the molecule instead of the usual two; it is a blue gas, generated from oxygen by electrical discharge.

   Hypernym: greenhouse gas

2. (British, informal) Fresh air, especially that breathed at the seaside and smelling of seaweed.
   • 1875, William Crookes, The Chemical News, page 99,

     A patent obtained in England, and specified far from clearly, for obtaining ozone by boiling seaweed,†† may be mentioned as a curiosity, and also the credulity with which ozone-baths, prepared in this manner, find a ready sale, in spite of, or perhaps rather on account of, their high price.

   • 1888, L. T. Meade, A. Balfour Symington, Edwin Oliver, Atalanta, Volume 1, page 674,

     To Ramsgate baths she sped, in quest / Of seaweed and ozone ; / For seaweed and ozone were best, / They said, to give her tone.

   • 2007, Robert Douglas, Tales of the Unexpected, Somewhere to Lay My Head, unnumbered page,

     It's got the lot: fresh sea air, ozone, seaweed. You could cut the air with a knife.
