Merriam-Webster's Word of the Day

Merriam-Webster's Word of the Day for December 13, 2025 is: alleviate • \uh-LEE-vee-ayt\  • verb To alleviate something is to make it less painful, difficult, or severe. Alleviate can also mean "to partially remove or correct." // There's no cure for the common cold, but there are various treatments that may alleviate some of the symptoms. // The new tunnel should alleviate traffic congestion on the bridge. See the entry > Examples: "The funds are meant to alleviate monetary barriers and enhance the fashion industry's talent pipeline." — Rosemary Feitelberg, Footwear News, 30 Oct. 2025 Did you know? Now for a bit of light reading. Alleviate comes from Latin levis, meaning "having little weight." (Levis also gave rise to the English adjective light as in "not heavy.") In its early days during the 16th century, alleviate could mean both "to cause (something) to have less weight" or "to make (something) more tolerable." The literal "make lighter" sense is no longer used, and today only the "relieve, lessen" sense remains. Incidentally, not only is alleviate a synonym of relieve, it's also a cousin: relieve comes from Latin levare ("to raise"), which in turn comes from levis.

Merriam-Webster's Word of the Day for December 12, 2025 is: waggish • \WAG-ish\  • adjective Waggish describes someone who is silly and playful, and especially someone who displays a mischievous sense of humor. The word can also describe things that such a person might do or possess. // He had a waggish disposition that could irk adults but typically delighted children. // She denied the prank but did so with a waggish smirk that didn't match her disavowal. See the entry > Examples: “[Patricia] Lockwood began her writing life quietly, as a poet. She found her first major audience on Twitter, posting self-proclaimed ‘absurdities’ ... that quickly came to define the medium’s zany, waggish ethos ...” — Alexandra Schwartz, The New Yorker, 25 Aug. 2025 Did you know? One who is waggish acts like a wag. What, then, is a wag? It has nothing to do with a dog’s tail; in this case a wag is a clever person prone to joking. Though light-hearted in its use and meaning, the probable source of this particular wag is grim: it is thought to be short for waghalter, an obsolete English word that translates as gallows bird, a gallows bird being someone thought to be deserving of hanging (wag being the familiar wag having to do with movement, and halter referring to a noose). Despite its gloomy origins, waggish is now often associated with humor and playfulness—a wag is a joker, and waggery is merriment or practical joking. Waggish can describe the prank itself as well as the prankster type; the class clown might be said to have a “waggish disposition” or be prone to “waggish antics.”

Merriam-Webster's Word of the Day for December 11, 2025 is: leviathan • \luh-VYE-uh-thun\  • noun Leviathan is a word with literary flair that can refer broadly to something very large and powerful, or more narrowly to a large sea animal, or a totalitarian state having a vast bureaucracy. // Towering leviathans of the forest, giant sequoias often reach heights of more than 200 feet. See the entry > Examples: “These are dim days for the leviathan merchants. The smart whaling families have diversified and will hang onto their wealth for years to come. ... The less smart, those convulsed by the strange desire to continue doing what had always been done, who consider it a divinely issued directive to rid the waves of great fish, now face a problem: the Atlantic whale that built their houses and ships has seemingly wised up ...” — Ethan Rutherford, North Sun, or The Voyage of the Whaleship Esther: A Novel, 2025 Did you know? Old Testament references to a huge sea monster, Leviathan (in Hebrew, Liwyāthān), are thought to have been inspired by an ancient myth in which the god Baal slays a multiheaded sea monster. Leviathan appears in the Book of Psalms as a sea serpent that is killed by God and then given as food to creatures in the wilderness, and it is mentioned in the Book of Job as well. After making a splash in English in the 1300s, the word Leviathan began to be used, capitalized and uncapitalized, for enormous sea creatures both imagined and real—including as a synonym of whale over 100 times in Herman Melville’s Moby-Dick, as in “ere the Pequod’s weedy hull rolls side by side with the barnacled hulls of the leviathan.” Today, leviathan can be used for anything large and powerful, from ships to corporations.

Merriam-Webster's Word of the Day for December 10, 2025 is: grift • \GRIFT\  • verb To grift is to use dishonest tricks to illegally take money or property. // The email scammer shamelessly grifted thousands of dollars from unwitting victims. See the entry > Examples: "When the families demanded he return the jewellery he had grifted from them he arranged meetings and then did not show." — Peter Spriggs, The Echo (South Essex, England), 31 Oct. 2025 Did you know? Someone who grifts is a thief, but of a particular sort: they illegally obtain money or property by means of cleverness or deceit, and do not usually resort to physical force or violence. A grifter might be a pickpocket, a crooked gambler, a scammer, or a con artist. The most plausible etymology we have for the murky term is that grift is an early 20th century alteration of graft, a slightly older word which refers to the acquisition of money or property in dishonest or questionable ways. Both grift and graft have noun and verb forms.

Merriam-Webster's Word of the Day for December 9, 2025 is: paltry • \PAWL-tree\  • adjective Paltry is a formal word that can describe something that is very small or too small in amount, or something that has little meaning, importance, or worth. // They're offering a paltry salary for the position. // The professor announced they'd finally had enough of the students' paltry excuses for being late to class. See the entry > Examples: "When the witty and wry English fantasy novelist Terry Pratchett interviewed Bill Gates for GQ in 1995, only 39% of Americans had access to a home computer. According to the Pew Research Center, the number who were connected to the internet was a paltry 14%." — Ed Simon, LitHub.com, 25 Nov. 2024 Did you know? Before paltry was an adjective, it was a noun meaning trash. That now-obsolete noun came from palt or pelt, a dialect term referring to a piece of coarse cloth, or more broadly, to trash. The adjective paltry, which dates to the mid-16th century, originally described things considered worthless, or of very low quality, but it's gained a number of meanings over the centuries, none of which are complimentary. A paltry house might be neglected and unfit for occupancy; a paltry trick is a trick that is low-down and dirty; a paltry excuse is a poor one; and a paltry sum is small and insufficient.

Merriam-Webster's Word of the Day for December 8, 2025 is: bravado • \bruh-VAH-doh\  • noun Bravado refers to confident or brave talk or behavior that is intended to impress other people. // She tells the stories of her youthful exploits with enough bravado to invite suspicion that they're embellished a bit. // The crew of climbers scaled the mountain with youthful bravado. See the entry > Examples: "One problem that exists in the whitewater community overall is that people don't always understand the basic elements associated with water and their ignorance and bravado often lead to an incident where someone gets injured or killed." — Tracy Hines, The Durango (Colorado) Herald, 19 Oct. 2025 Did you know? Displays of bravado may be show-offish, daring, reckless, and inconsistent with good sense—take, for example, the spectacular feats of stuntpeople—but when successful, they are still likely to be met with shouts of "bravo!" Celebrities, political leaders, corporate giants, and schoolyard bullies, however, may show a different flavor of bravado: one that suggests an overbearing boldness that comes from arrogance or from being in a position of power. The word bravado originally comes from the Italian adjective bravo, meaning "wild" or "courageous," which English can also thank for the more common brave.

Merriam-Webster's Word of the Day for December 7, 2025 is: enigmatic • \en-ig-MAT-ik\  • adjective Something or someone described as enigmatic is mysterious and difficult to understand. // The band’s lead singer has always been an enigmatic figure, refusing to use social media or even sit for interviews. See the entry > Examples: “For thirty years, Perlefter’s carpet hung peacefully on the wall in the museum, delighting visitors with its beauty, its unusual palette, enigmatic motifs and its echoes of four empires.” — Dorothy Armstrong, Threads of Empire: A History of the World in Twelve Carpets, 2025 Did you know? The noun enigma can refer to a puzzle, a riddle, a question mark. It’s no mystery then, that the adjective enigmatic describes what is hard to solve or figure out. An enigmatic person, for example, may be someone with a bit of je ne sais quoi. What’s behind a stranger’s enigmatic smile? Your guess is as good as ours. Does the vocabulary in the short story you’re reading render it a tad enigmatic? Better grab a dictionary! Both enigma and enigmatic come from the Greek verb ainissesthai, meaning “to speak in riddles.”

Merriam-Webster's Word of the Day for December 6, 2025 is: sensibility • \sen-suh-BIL-uh-tee\  • noun Sensibility is a formal word often used in its plural form to refer someone’s personal or cultural approach to what they encounter, as in “the speaker made sure to tailor his speech to the sensibilities of his audience.” Sensibility can also be used for the kind of feelings a person tends to have in general, as well as for the ability to feel and understand emotions. // Many older cartoons feel out of line with modern sensibilities. // She brought an artistic sensibility to every facet of her life, not just her celebrated painting. See the entry > Examples: “[Lady] Gaga’s absurdist sensibilities have long been an underrated facet of her work—probably because she’s so good at delivering them with a straight face.” — Rich Juzwiak, Pitchfork, 10 Mar. 2025 Did you know? The meanings of sensibility run the gamut from mere sensation to excessive sentimentality, but we’re here to help you make sense of it all. In between is a capacity for delicate appreciation, a sense often pluralized. In Jane Austen’s books, sensibility is mostly an admirable quality she attributes to, or finds lacking in, her characters: “He had ... a sensibility to what was amiable and lovely” (of Mr. Elliot in Persuasion). In Sense and Sensibility, however, Austen starts out by ascribing to Marianne sensibleness, on the one hand, but an “excess of sensibility” on the other: “Her sorrows, her joys, could have no moderation ... she was everything but prudent.”

Merriam-Webster's Word of the Day for December 5, 2025 is: inoculate • \ih-NAHK-yuh-layt\  • verb To inoculate a person or animal is to introduce immunologically active material (such as an antibody or antigen) into them especially in order to treat or prevent a disease. Inoculate can also mean "to introduce (something, such as a microorganism) into a suitable situation for growth," and in figurative use, it can mean "to protect as if by inoculation" or "to introduce something into the mind of." // In 1796, the English physician Edward Jenner discovered that inoculating people with cowpox could provide immunity against smallpox. // The cheese is inoculated with a starter culture to promote fermentation. See the entry > Examples: "Truffle farmers ... inoculate oak or hazelnut seedlings with truffle spores, plant the seedlings and wait patiently often a decade or more for the underground relationship to mature. The eventual harvest is a reward for years of cooperation between tree and fungus." — David Shubin, The Weekly Calistogan (Calistoga, California), 30 Oct. 2025 Did you know? If you think you see a connection between inoculate and ocular ("of or relating to the eye"), you have a good eye—both words look back to oculus, the Latin word for "eye." But what does the eye have to do with inoculation? Our answer lies in the original use of inoculate in Middle English: "to insert a bud into a plant for propagation." The Latin oculus was sometimes applied to things that were seen to resemble eyes, and one such thing was the bud of a plant. Inoculate was later applied to other forms of engrafting or implanting, including the introduction of vaccines as a preventative against disease.

Merriam-Webster's Word of the Day for December 4, 2025 is: frowsy • \FROW-zee\  • adjective Something described as frowsy has a messy or dirty appearance. // The lamp, discovered in a neglected corner of a frowsy antique store, turned out to be quite valuable. See the entry > Examples: “Footage from his early shows is sublime. In one, models with frowsy hair totter along the catwalk in clogs, clutching—for reasons not explained—dead mackerel.” — Jess Cartner-Morley, The Guardian (London), 4 Mar. 2024 Did you know? Despite its meanings suggesting neglect and inattention, frowsy has been kept in steady rotation by English users since the late 1600s. The word (which is also spelled frowzy and has enjoyed other variants over the centuries) first wafted into the language in an olfactory sense describing that which smells fusty and musty—an old factory, perhaps, or “corrupt air from animal substance,” which Benjamin Franklin described as “frouzy” in a 1773 letter. Frowsy later gained an additional sense describing the appearance of something (or someone) disheveled or unkempt. Charles Dickens was a big fan of this usage, writing of “frowzy fields, and cowhouses” in Dombey and Son and “a frowzy fringe” of hair hanging about someone’s ears in The Old Curiosity Shop. Both senses are still in use today.
