An oxymoron is a figure of speech that combines two contradictory terms for effect — like jumbo shrimp, deafening silence, or bittersweet.
Oxymorons aren’t grammar mistakes; they’re intentional and often playful, used to highlight irony or create a memorable phrase. Some favorites: original copy, awfully good, only choice, seriously funny, controlled chaos, open secret.
Writers use oxymorons to add humor, emphasis, or a touch of poetry to their sentences. Quick practice: what’s the contradiction in “small crowd”? (Answer: “small” suggests few, while “crowd” implies many.)
