Merriam-Webster's Word of the Day

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."

Merriam-Webster's Word of the Day for December 15, 2025 is: dreidel • \DRAY-dul\ • noun A dreidel is a 4-sided toy marked with Hebrew letters and spun like a top in a game of chance. The game, played by children especially at Hanukkah, is also called dreidel. // All the kids in the family look forward to playing dreidel together during Hanukkah. See the entry > Examples: “The Jewish tradition has always been syncretic, adapting and responding to the culture around it, he [Rabbi Steven Philp] said. Hanukkah is ‘a great example of this,’ Philp said, noting that the holiday’s traditions—like spinning the dreidel, eating latkes or potato pancakes, and munching on ... jelly-filled doughnuts—are customs that were borrowed from neighboring cultures over time.” — Kate Heather, The Chicago Sun-Times, 25 Dec. 2024 Did you know? If your dreidel is spinning beneath the glow of the menorah, it’s probably the Jewish festival of lights known as Hanukkah. The holiday celebrates the miracle of a small amount of oil—enough for one day—burning for eight days in the Temple of Jerusalem. And though it’s a toy, the dreidel’s design is very much an homage: on each of its four sides is inscribed a Hebrew letter—nun, gimel, he, and shin—which together stand for Nes gadol haya sham, meaning “A great miracle happened there.” (In Israel, the letter pe, short for po, “here,” is often used instead of shin). In the game of dreidel, each letter bears its own significance: the dreidel is spun and depending on which letter is on top when it lands, the player’s currency, or gelt, is added to or taken from the pot. Nun means the player does nothing; gimel means the player gets everything; he means the player gets half; and shin means the player adds to the pot. Wherever you land on holiday traditions, we wish you words of gimel: gratitude, grub, and, of course, gaiety.

Merriam-Webster's Word of the Day for December 14, 2025 is: multitudinous • \mul-tuh-TOO-duh-nus\ • adjective Multitudinous is a formal word with meanings that relate to multitudes. It can mean “existing in a great multitude”—that is, “very many”; or “including a multitude of individuals”; or “existing in or consisting of innumerable elements or aspects.” // The two old friends reminisced about the multitudinous ways in which their lives had changed. // The author’s appearance is expected to attract a multitudinous gathering that will fill the auditorium. See the entry > Examples: “Launched as Holton’s artistic inquiry into his own Chinese heritage, the project has evolved into a profound examination of family dynamics, migration, and cultural hybridity in contemporary New York, where the American identity is multitudinous.” — Natasha Gural, Forbes, 11 June 2025 Did you know? “I am large, I contain multitudes.” So wrote Walt Whitman in his most celebrated poem, “Song of Myself.” He was expressing his ability to hold within himself contradictory statements, facets, opinions, beliefs, etc. Another, if less poetic, way of saying “I contain multitudes” might be “I am multitudinous,” using the sense of that five-syllable word meaning “existing in or consisting of innumerable elements or aspects.” Multitudinous doesn’t have a lot of meanings—three to be exact—but each one concerns, well, a lot. In addition to serving Whitmanesque purposes as noted above, multitudinous is the kind of highly expressive word that you can rely upon when you want something a little more emphatic than plain old numerous, as in “multitudinous possibilities.” Lastly, its original sense—still in use today—is a synonym of populous meaning “including a multitude of individuals,” as in “the multitudinous city.”
