Examples:

“Until now I thought ‘enjoyable science book’ was an oxymoron. [Author, Katie] Spalding proved me wrong. I learned a lot and had fun doing it. Turns out a spoonful of snark helps the factoids go down—in a most delightful way.” — Curt Schleier, The Star Tribune (Minneapolis, Minnesota), 19 May 2023

Did you know?

The ancient Greeks exhaustively classified the elements of rhetoric, or effective speech and writing, and gave the name oxymoron—literally "pointed foolishness"—to the deliberate juxtaposing of seemingly contradictory words. The roots of oxymoron, oxys meaning "sharp" or "keen," and mōros meaning "foolish," are nearly antonyms themselves, making oxymoron nicely self-descriptive. Oxymoron originally applied to a meaningful paradox condensed into a couple of words, as in "precious bane," "lonely crowd," or "sweet sorrow." Today, however, what is commonly cited as an oxymoron is often simply a curiosity of language, where one or both elements have multiple meanings (shrimp in "jumbo shrimp" doesn't mean "small"; it refers to a sea creature), or a phrase whose elements seem antithetical in spirit, such as "organized chaos."
