Etymology

Origin of oxymoron

First recorded in 1650–60; from Late Latin oxymorum, from presumed Greek oxýmōron (unrecorded), neuter of oxýmōros (unrecorded) “sharp-dull,” equivalent to oxý(s) “sharp” ( oxy- 1 ) + mōrós “dull” ( moron )

Explanation

Jumbo shrimp? Open secret? Use oxymoron to refer to a word or phrase that contradicts itself, usually to create some rhetorical effect. When Shakespeare's Juliet says, "Parting is such sweet sorrow," she is using an oxymoron; her apparently self-contradictory turn of phrase actually makes a neat kind of sense. Oxymoron is sometimes used to describe a word combination that strikes the listener as humorously contradictory, even if the speaker didn't intend it that way. The word oxymoron is itself an oxymoron; in Greek, oxy- means "sharp" or "wise," while moros means "foolish."
