Examples:
“… Liverpool is famed for its nightlife, but I’m getting the impression it could do with some help. … In December 2023, the ECHO spoke to people in Liverpool’s late-night economy, and the prevailing view was it had become a struggle. … Prices don’t help—drinks and tickets are more expensive than they’ve ever been, but venues are stuck in a Catch-22 situation, caught between having to cover huge operating costs and wanting to get people through the doors.” — Dan Haygarth, The Liverpool Echo (Liverpool, England), 23 Aug. 2025

Catch-22 originated as the title of a 1961 novel by Joseph Heller. (Heller had originally planned to title his novel Catch-18, but the publication of Leon Uris’s Mila 18 persuaded him to change the number.) The catch-22 in Catch-22 involves a mysterious Army Air Forces regulation which asserts that a man is considered mentally unsound if he willingly continues to fly dangerous combat missions but that if he makes the necessary formal request to be relieved of such missions, the very act of making the request proves that he is sane and therefore ineligible to be relieved. Catch-22 soon entered the language as a label for any irrational, circular, and impossible situation.

Examples:
“On opening night, the audience at St. Petersburg’s Alexandrinsky Theatre were mystified by The Seagull’s neither wholly comic nor wholly tragic tone, hissing and heckling throughout, with Chekhov fleeing from the gallery after the second act. It was only two years later, when Konstantin Stanislavski staged a more lugubrious take on The Seagull at Moscow Art Theatre, that it came to be recognized as a work of pure genius.” — Hayley Maitland, Vogue, 12 Feb. 2025

Everybody hurts, as the classic R.E.M. song goes, and when your day is long and the night is yours alone, lugubrious is a perfect word for describing such sorrowful feelings, or that which inspires them (a lugubrious song, perhaps). That said, if lugubrious strikes you as a tad unusual, no, no, no, you’re not alone. Lugubrious is the sole surviving English offspring of the Latin verb lugēre, meaning “to mourn.” Its closest kin, luctual, an adjective meaning “sad” or “sorrowful,” was laid to rest centuries ago.

enmity • \EN-muh-tee\ • noun

Examples:
"Paul Monreal is a fourth-great-grandchild of Catherine and Patrick O'Leary, who endured the enmity of Chicagoans after they were wrongfully accused of starting the Great Chicago Fire, which legend said was started by a jittery dairy cow named Daisy." — William Lee, The Chicago Tribune, 5 July 2025
Did you know?
The resemblance between enmity and enemy is no coincidence: both words come from the Anglo-French word enemi, which literally translates to "enemy." And when you feel enmity for a particular person—that is, deep-seated dislike or ill will—"enemy" may very well be an apt descriptor for them. While it is possible to feel enmity for someone who does not share or return one’s animosity, enmity is typically used for mutual hatred or antagonism between people (or groups, factions, etc.), as when Edgar Allan Poe wrote of the families of Berlifitzing and Metzengerstein in his first published short story: "Never before were two houses so illustrious, mutually embittered by hostility so deadly. The origin of this enmity seems to be found in the words of an ancient prophecy—'A lofty name shall have a fearful fall ...'"

Examples:
“Occasionally, Dope Girls does succumb to style over substance, as if it doesn’t quite have the confidence to let its big, bold narrative unfold without any bells and whistles.” — Jon O’Brien, The Daily Beast, 8 Aug. 2025
Did you know?
Picture yourself serenely succumbing to sleep. Chances are that in the mental image you’ve just formed, you are in a recumbent position—that is, lying down. The position is baked into the etymology: both succumb and recumbent trace back to cumbere, a Latin verb meaning “to lie down.” While recumbency is typically literal, succumbing is about figuratively lying down before something—yielding to it, ceasing to resist it. The word is most often used with regard to faults and foibles and demise—people succumb to temptation, plants succumb to blight—but the word can be applied in happier contexts too, as when one succumbs to sleep in a quiet spot on a sunny afternoon.

Examples:
“There is a rationale for commercializing seagrass production, but ecologically sustainable production needs to be at the heart of that business model, and the numbers for doing that simply don’t add up at the moment.” — Richard Lilley, quoted in Smithsonian Magazine, 7 Oct. 2024

If someone asserts that the word rationale refers to a ration of ale, they are wrong, but that doesn’t mean they don’t have an actual rationale (a reason, explanation, or basis) for such a claim. “Rationale looks like the words ration and ale jammed together,” they could offer, and while that is true you’d be justified in responding: “Appearances can be deceiving.” Rationale is a direct borrowing of the Latin word rationale, with which it shares the meaning “an explanation of controlling principles of opinion, belief, practice, or phenomena.” The Latin rationale comes from a form of the adjective rationalis (“rational”), which traces back to the noun ratio, meaning “reason.” While the Latin ratio is also the forebear of the English noun ration, referring to a share of something, rationale has nothing to do with a tankard (or stein, or even a pony) of beer.
