Pronunciation

  • 5th-century BC Attic: /ok.sý.mɔː.ron/[1]
  • 4th-century AD Koine: /okˈsy.mo.ron/[1]
  • 10th-century Byzantine: /okˈsy.mo.ron/[1]

Forms

ὀξῠ́μωρον (oxúmōron) n (genitive ὀξυμώρου); second declension; the neuter of the adjective ὀξύμωρος, ὀξύμωρον.[2][1]

Etymology

It is the neuter, used as a noun, of the adjective ὀξύμωρος (oxúmōros, “pointedly foolish”).[2][1][3] The adjective is a compound from Ancient Greek ὀξύς (oxús, “sharp, keen”) + μωρός (mōrós, “dull, foolish”),[1][4][5] so that the word itself joins two contradictory ideas, the very figure it names.[3] Etymonline traces ὀξύς (oxús) to Proto-Indo-European *ak- (“to be sharp”).[3]

Earliest recorded meaning

The adjective means “pointedly foolish”, and the neuter τὸ ὀξύμωρον is a witty saying whose point is sharpened by being paradoxical or seemingly absurd.[2][6] The term is cited from the Latin commentator Servius, on Vergil's Aeneid 7.295, who uses it for phrases such as Latin insaniens sapientia (“mad wisdom”) and strenua inertia (“busy idleness”).[2][4]

Semantic evolution

The word belonged to the vocabulary of grammarians and rhetoricians, for a clever union of two notions that seem to exclude each other.[6][4][7] Modern Greek took it back as a learned word from the post-classical language: Modern Greek οξύμωρος (oxýmoros) means “self-contradictory, paradoxical”, and οξύμωρο σχήμα is the figure of speech that joins opposite notions to express something true.[8][9][10]

English borrowed the noun as oxymoron in the 1650s as a rhetorical term; it is now often used loosely for any contradiction in terms.[3]

Timeline

  • Hellenistic and Roman period – The compound adjective ὀξύμωρος is in use, its neuter as a term of rhetoric.[8][9][6]
  • 1650s – English borrows the noun as the rhetorical term oxymoron.[3]
  • Modern Greek – The learned adjective οξύμωρος (oxýmoros) means “contradictory”, and οξύμωρο σχήμα names the figure of speech.[8][10]

Meanings
