Merriam-Webster's Word of the Day

Merriam-Webster's Word of the Day for December 22, 2025 is: temporize • \TEM-puh-ryze\ • verb To temporize is to avoid making a decision or giving a definite answer in order to have more time. // Pressured by voters on both sides of the issue, the congressman temporized. See the entry > Examples: "The question is, Did you eat the last piece of pie? And the politician who ate the last piece of pie doesn't want to say yes, because they might get in trouble. Doesn't want to say no, because that's an outright lie. So they waver, they equivocate, they temporize, they put things in context, and they talk like a politician." — David Frum, The Atlantic (The David Frum Show podcast), 21 May 2025 Did you know? Temporize comes from the Middle French word temporiser, which in turn likely traces back via Medieval Latin temporizāre, "to delay," to the Latin noun tempus, meaning "time." Tempus is also the root of such words as tempo, contemporary, and temporal. If you need to buy some time, you might resort to temporizing, but you probably won't win admiration for doing so, as the word typically carries a negative connotation. For instance, a political leader faced with a difficult issue might temporize by talking vaguely about possible solutions without actually doing anything. The point of such temporizing is to avoid taking definitive—and possibly unpopular—action, in hopes that the problem will somehow go away.

Merriam-Webster's Word of the Day for December 21, 2025 is: hibernaculum • \hye-ber-NAK-yuh-lum\ • noun Hibernaculum (plural hibernacula) refers to a shelter occupied during the winter by a dormant animal, such as an insect, snake, bat, or marmot. // Local scientists are studying the longevity of bats who use bridges and other aboveground hibernacula versus that of bats who roost all winter in subterranean caves. See the entry > Examples: “Adult female bees begin looking for a hibernation location, or hibernaculum, in the fall. If the gardener is planning to deadhead any spent flowers from the summer, aim to prune stems at varying heights (8" to 24") as a nesting site for these bees. Many perennial flowers and shrubs have pithy stems that will serve as a good location. A few common Oklahoma garden plants that are good candidates include roses, purple coneflower, salvia, bee balm, and sunflowers.” — Sherry Clark, The Shawnee (Oklahoma) News-Star, 8 Oct. 2025 Did you know? If you’re afraid of snakes or bats, you probably won’t enjoy thinking about hibernacula, where hundreds, even thousands, of these creatures might be passing the wintry months. Other creatures also use hibernacula, though many of these tend to be less crowded. The word hibernaculum has been used for the burrow of a woodchuck, for instance, as well as for a cozy caterpillar cocoon attached to a wintry twig, and for the spot in which a frog has buried itself in mud. Hibernacula are all around us and have been around for a long, long time, but we have only called them such since the late 1700s, making hibernaculum only a few decades older than the more familiar verb hibernate. Both words come from the Latin verb hibernare, meaning “to pass the winter,” which in turn comes from hibernus, meaning “winter.”

Merriam-Webster's Word of the Day for December 20, 2025 is: decorous • \DECK-er-us\ • adjective Decorous is a formal adjective used to describe an attitude or behavior characterized by propriety and good taste. // The ceremony was conducted with a decorous solemnity. See the entry > Examples: “... Elizabeth reveals, later, that she felt she never belonged to the decorous world of parties and corsets and curls and feathers on the head ...” — Ryan Lattanzio, Indie Wire, 13 Oct. 2025 Did you know? One of the earliest recorded uses of decorous appears in a book titled The Rules of Civility (1671): “It is not decorous to look in the glass, to comb, brush, or do any thing of that nature to ourselves, whilst the said person be in the Room.” This rule of thumb may be a bit outdated; like many behaviors once deemed unbecoming, public primping is unlikely to offend in modern times. Though mores shift, decorous lives on to describe timeless courtesies like polite speech, proper attire, and (ahem) covering one’s cough.

Merriam-Webster's Word of the Day for December 19, 2025 is: veracity • \vuh-RASS-uh-tee\ • noun Veracity is a formal word that can refer to truth or accuracy, or to the quality of being truthful or honest. // The jury seemed not to doubt the veracity of the witness. See the entry > Examples: "Raise your hand if you've been questioning the veracity of real events, news stories and images posted on social media lately. It used to be we'd have to tiptoe around a minefield of hoaxes only once a year, on April 1. But thanks to the proliferation of misinformation spawned by artificial intelligence, every day on the internet is an exercise in judgment and media literacy." — Laura Yuen, The Hamilton (Ontario) Spectator, 9 Oct. 2025 Did you know? Veracity has been in use since the early 17th century, and we can honestly tell you that it comes from the Latin adjective vērāx, "truthful," which in turn comes from the earlier verus, "true." Verus also gives us the words verity ("the quality of being true"), verify ("to establish the truth of"), and verisimilitude ("the appearance of truth"), among other words. In addition, vērāx is the root of the word veraciousness, a somewhat rarer synonym and cousin of veracity.

Merriam-Webster's Word of the Day for December 18, 2025 is: jaunty • \JAWN-tee\ • adjective Something described as jaunty is lively in manner or appearance. Jaunty can also describe something, such as an article of clothing, that suggests a lively and confident quality. // The server whistled a jaunty tune as she wiped the tables and set out fresh flowers in preparation for the day’s diners. See the entry > Examples: “He stood at the front of the room and announced that we would begin with a quiz, which we all failed because the quiz was over material that we were supposed to have covered during the last class. When he handed the quizzes back to us after the break, he did so in a frenetic, almost jaunty way, running up and down the aisles and announcing our grades—‘Zero, zero, zero’—loudly before tossing the quizzes down in front of us ...” — Lori Ostlund, Are You Happy?: Stories, 2025 Did you know? Does throwing on a jaunty hat make someone appear more genteel? Maybe, but something more definitive links the words: both jaunty and genteel come from the French word gentil, meaning “of aristocratic birth.” Genteel was borrowed first to describe things associated with aristocratic people. Jaunty joined the language just a few years later in the mid-17th century as a synonym of stylish and also as a synonym for genteel. While genteel has maintained its associations of propriety and high social class, jaunty has traipsed into less stuffy territory as a descriptor of tunes and hats and other things that suggest lively confidence.
