File under “Moron, Oxy”: Not all oxymorons are nonsensical.
An oxymoron is a figure of speech or a style of argumentation that combines seemingly disparate elements, and we often think of it as a self-contradicting phrase. George Carlin used “jumbo shrimp” as an example (one that the literate Mr. Carlin may not realize is even more oxymoronic when you consider that the word shrimp is related to words meaning “shrivel,” including scrimp, difficult to do when buying high-priced jumbo shrimp).
But the idea of an apparent oxymoron that makes sense? You might think that that bizarre notion comes out of left field. Nope. In fact, the original Greek word denotes intentionally making a point by utilizing incongruity, something of the type of opposite approach employed in sarcasm or facetiousness.
That’s on a higher philosophical level. On a more granular word-by-word level, you’ll regularly find instances of apparently contradictory words working harmoniously. For instance, that bizarre notion of coming out of left field. It didn’t come out of left field because it’s still “out in” left field.
