Merriam-Webster's Word of the Day

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 This rule of thumb may be a bit outdated; like many behaviors once deemed unbecoming, public primping is unlikely to offend in modern times.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.

Merriam-Webster's Word of the Day for December 17, 2025 is: espouse • \ih-SPOWZ\ • verb To espouse an ideology, belief, etc., is to take it up and support it as a cause. Espouse is usually encountered in formal speech and writing. // The article explores some of the lesser-known viewpoints espoused by the charismatic leader. See the entry > Examples: “Crammed into a tiny apartment in Greenwich Village, they [Yoko Ono and John Lennon] immersed themselves in the city’s counterculture, absorbing progressive politics whenever they weren’t glued to the television set. Lennon’s celebrity secured the duo a large platform to espouse these ideas ...” — Stephen Thomas Erlewine, Pitchfork, 11 Oct. 2025 Did you know? As you might guess, the words espouse and spouse are hitched, both coming from the Latin verb spondēre, meaning “to promise” or “to betroth.” In fact, the two were once completely interchangeable, with each serving as a noun meaning “a newly married person” or “a partner in marriage” and also as a verb meaning “to marry.” Their semantic separation began when the noun espouse fell out of use. Nowadays, espouse is almost exclusively encountered as a verb used in the figuratively extended sense “to commit to and support as a cause.”

Merriam-Webster's Word of the Day for December 16, 2025 is: conversant • \kun-VER-sunt\ • adjective Conversant, usually used in the phrase "conversant with," describes someone who has knowledge of or experience with something. // The ideal candidate for the sommelier position will have expert knowledge of the various wines served in the restaurant and be conversant with the rich world of viniculture. See the entry > Examples: "The advantages of franchise expansion are obvious. These shows benefit from name recognition and a dedicated audience, as well as writers, producers and crew members already conversant with that audience's expectations." — Alexis Soloski, The New York Times, 6 July 2025 Did you know? The adjectives conversant and conversational both descend from the Latin verb conversari, meaning "to associate with." Conversant dates to the Middle Ages; an early meaning of the word was simply "having familiar association." One way to associate with others is to have a conversation with them—in other words, to talk. For a short time in the 19th century conversant could mean "relating to or suggesting conversation," but for the most part that meaning stayed with conversational while conversant went in a different direction. Today, conversant is sometimes used, especially in the United States, with the meaning "able to talk in a foreign language," as in "she is conversant in several languages," but it is more often associated with knowledge or familiarity, as in "conversant with the issues."
