oxymoron

Etymology and origin of the English word oxymoron

Pronunciation

  • IPA: /ˌɑksiˈmɔɹɑn/, /ɑksɪˈmɔɹɑn/; /ɒksɪˈmɔːɹɒn/ (UK)[1]

Etymology

It is borrowed from Ancient Greek ὀξύμωρον (oxúmōron),[2][3][4][5] the neuter of oxúmōros “pointedly foolish”,[2][3][4][5] from Ancient Greek ὀξύς (oxús, “sharp, keen”) + μωρός (mōrós, “foolish, dull”).[2][3][4][5][6] Merriam-Webster labels the source Late Greek, and RHWU traces it through Late Latin oxymorum to a presumed Greek form.[5][6] The word is itself an example of what it names.[4]

Earliest recorded meaning

In rhetoric, a figure that joins apparently contradictory or incongruous terms to give point to an expression.[4][7]

Semantic evolution

It is now often used loosely of any contradiction in terms, or of something made up of contradictory elements;[4][5][1] some writers regard this use as incorrect.[1]

Timeline

  • 1640 – the OED's first quotation;[7] Etymonline gives the 1650s, and Merriam-Webster and Barnhart 1657.[4][5][3]

Modern meaning

Noun

  1. A figure of speech combining contradictory or incongruous words, as in deafening silence or cruel kindness.
  2. Loosely, a contradiction in terms; something made of contradictory elements.

Usage notes

Historically an oxymoron was a deliberate paradox meant to make or reveal a point; the loose use for any contradiction in terms is considered incorrect by some, and may be best avoided in careful writing.[1]
