Merriam-Webster's Word of the Day

Merriam-Webster's Word of the Day for March 9, 2026 is: hector • \HEK-ter\  • verb To hector someone is to criticize or question them in a threatening way. // The judge ordered the attorney to stop hectoring the witness. See the entry > Examples: “He continued to hector Neal about his inattention to business (‘I have been waiting to hear from you,’ again, and again, and again), without any tangible results.” — Jem Aswad, Variety, 5 Aug. 2025 Did you know? In Homer’s Iliad, Hector, the eldest son of King Priam of Troy, was a model soldier, son, father, and friend, the champion of the Trojan army until he was killed by the Greek hero Achilles. So how did his name become a verb meaning “to intimidate or harass”? That use was likely influenced by gangs of rowdy street toughs who roamed London in the 17th century and called themselves “Hectors.” They may have thought themselves gallant young blades (that’s sense 3b(3)), but to the general populace they were swaggering bullies who intimidated passersby and vandalized property.

Merriam-Webster's Word of the Day for March 8, 2026 is: crepuscular • \krih-PUHSS-kyuh-ler\  • adjective Crepuscular means “of, relating to, or resembling twilight.” It is used in zoological contexts to describe creatures that are active during twilight, or the activities of such creatures. // As evening came on, fireflies began to appear in the crepuscular gloaming. See the entry > Examples: “To gaze upon a platypus is to witness a jumble of contradictions. … Even when you see one with your own eyes—say, paddling underwater, absorbed in her crepuscular rooting—the platypus (Ornithorhynchus anatinus) remains hard to believe.” — Kathleen Yale, Orion, Winter 2025/2026 Did you know? The early Romans had two words for the twilight. Crepusculum was favored by Roman writers for the half-light of evening, just after the sun sets; diluculum was reserved for morning twilight, just before the sun rises—it is related to lūcidus, meaning “bright.” (Crepusculum was likely modeled on diluculum, from the assumed root krepos-, meaning “twilight.”) English speakers didn’t embrace either of these Latin nouns as substitutes for the word twilight, but they did form the adjective crepuscular in the 17th century. The word’s zoological sense, relating to animals that are most active at twilight, developed in the 19th century.

Merriam-Webster's Word of the Day for March 7, 2026 is: libertine • \LIB-er-teen\  • noun A libertine is in broad terms a person who is unrestrained by convention or morality. More narrowly, the word describes someone who leads an immoral life. // The legend of Don Juan depicts him as a playboy and libertine. See the entry > Examples: "As horrifying as some of the sins of Victorian scholarship may have been, it would have been anathema to these students of classical philosophy to simply throw out Plato. But that's what some of their modern inheritors have tried to do. … It's worth noting that we might not have Plato's work at all, were it not carefully studied and preserved by the Islamic scholars (hardly libertines themselves) of the medieval period." — R. Bruce Anderson, The Ledger (Lakeland, Florida), 1 Feb. 2026 Did you know? "I only ask to be free," says Mr. Skimpole in Charles Dickens' Bleak House. His words would undoubtedly have appealed to the world's first libertines. The word libertine comes from the Latin lībertīnus, a word used in early writings of Roman antiquity to describe a formerly enslaved person who had been set free (the Roman term for an emancipated person was the Latin lībertus). Middle English speakers used libertine to refer to a freedman, but by the late 1500s its meaning was extended to freethinkers, both religious and secular, and it later came to imply that an individual was a little too unrestrained, especially in moral affairs. The likely Latin root of libertine is līber, the ultimate source of our word liberty.

Merriam-Webster's Word of the Day for March 6, 2026 is: vaunted • \VAWN-tud\  • adjective Vaunted describes someone or something that is often spoken of or described as very good or great. // The team’s vaunted defense faltered in the second half of the game. See the entry > Examples: “After much initial hype, the much vaunted new production partnership fizzled out after just two seasons, leaving the franchise scrambling for a new direction and without a lead actor in its signature role.” — Lacy Baugher, Den of Geek, 22 Jan. 2026 Did you know? The verb vaunt has been used since the 15th century with the meaning “to make a vain display of one’s own worth or attainments”—in other words, “to brag or boast.” Over time, vaunt developed the meaning “to boast of (a particular thing),” as in “the promotional flier vaunts the natural beauty of the area,” and that use gave rise to the adjectival form vaunted. The history of vaunt and vaunted leads back to the Latin word vānus, with the meanings “lacking content, empty, illusory, marked by foolish or empty pride.” The word vain itself is also a descendant of vānus.

Merriam-Webster's Word of the Day for March 5, 2026 is: deem • \DEEM\  • verb Deem is a somewhat formal word used when someone comes to think something or to have something as an opinion after some consideration. // The covered bridge was closed to automobile traffic for the winter because town officials deemed it a hazard to motorists. See the entry > Examples: “bbno$ is an artist who has certainly taken some flak over the years for his style. Some find it to be a gimmick, while others deem it corny. Despite this, he does have a pretty sizable fanbase.” — Alexander Cole, HotNewHipHop.com, 10 Jan. 2026 Did you know? If you feel a sense of doom when asked to define deem, we’re here with some details for your dome (sense 7). While today deem is used generally as a synonym of consider (as in “a movie deemed appropriate for all ages”), its origins are more formal, coming specifically from the realm of law. The oldest meaning of deem, which comes from the Old English verb dēman (relative of dōm, meaning “doom”) is “to sit in judgment upon,” as employed by Edmund Spenser in The Faerie Queen: “... at th’one side six Judges were dispos’d, / To view and deem the deeds of arms that day.” This sense was obsolete by the early 17th century, and other senses including “to expect or hope” have come and gone, but deem’s use overall has never dimmed. In fact, today’s most common meaning of “to come to think or judge something; to consider” has also been in use since Old English and is still deemed quite common.

Merriam-Webster's Word of the Day for March 4, 2026 is: ad hoc • \AD-HOCK\  • adjective Ad hoc describes something that is formed or used for a special purpose, or that is made or done without planning because of an immediate need. // An ad hoc committee was formed to investigate the matter. // The company will hire more staff on an ad hoc basis. See the entry > Examples: "At the centre of the plan were tools designed to help governments and councils move beyond ad hoc responses to extreme weather." — Kirsty Johnston, The New Zealand Herald, 31 Jan. 2026 Did you know? In Latin ad hoc literally means "for this," and in English the term describes anything that can be thought of as existing "for this purpose only." For example, an ad hoc committee is generally authorized to look into a single matter of limited scope, not to broadly pursue any issue of interest. Ad hoc can also be used as an adverb meaning "for the particular end or case at hand without consideration of wider application," as in "decisions were made ad hoc."

Merriam-Webster's Word of the Day for March 3, 2026 is: spiel • \SPEEL\  • noun A spiel is a fast speech that someone has often said before and that is usually intended to persuade people to buy something or to agree to something. // The founder gave us a long spiel about the benefits of joining the running club. See the entry > Examples: “We were in a hotel and when he and his publicist exited one door of the suite, I slipped out the other to meet him at the elevator. I gave him my spiel about the film and handed him a rough cut on VHS. He said, ‘Alright, we’ll take a look.’” — Ed Burns, quoted in The Hollywood Reporter, 21 Jan. 2026 Did you know? Here’s our spiel on spiel: it’s well-known as a noun, and you may also be aware that spiel can be used as a verb meaning “to talk extravagantly,” but did you know that the verb can also mean “to play music”? That, in fact, is the word’s original meaning, and one it shares with its German root, spielen. Spiel is also found in glockenspiel, the name of a musical instrument similar to the xylophone.

Merriam-Webster's Word of the Day for March 2, 2026 is: exhilarate • \ig-ZIL-uh-rayt\  • verb Exhilarate means "to cause (someone) to feel very happy and excited." It is usually used in the passive voice as (be) exhilarated. // She was exhilarated by the prospect of attending her dream school. See the entry > Examples: "I'll say it: winter is my favorite season for jazz in Chicago. Summer may be busier and splashier, but there's nothing quite like nestling into a darkened club, cheeks flushed from the cold, for a singular and inventive night of music. It does more than thaw frozen fingers: It exhilarates, inspires and inflames, in the best way." — Hannah Edgar, The Chicago Tribune, 11 Jan. 2026 Did you know? Many people find exhilarate a difficult word to spell. It's easy to forget that silent "h" in there, and is it an "er" or "ar" after the "l"? It may be easier to remember the spelling if you know that exhilarate ultimately comes from the Latin adjective hilarus, meaning "cheerful." (This also explains why the earliest meaning of exhilarate is "to make cheerful.") Exhilarate comes from exhilaratus, a form of exhilarare, which combines ex- and hilarare, a verb from hilarus that means "to cheer or gladden." If hilarus looks familiar, that may be because it's also the source of hilarious and hilarity (as well as hilariously and hilariousness, of course).

Merriam-Webster's Word of the Day for March 1, 2026 is: paean • \PEE-un\  • noun Paean is a literary word that refers to a song of joy, praise, or victory. It can also be used as a synonym of tribute for a work that praises or honors its subject. // Her retirement party featured many paeans for her long years of service to the company. // Critics considered the movie both a thrilling Western and a paean to the natural beauty of the Rockies. See the entry > Examples: “The show is a tender study of people struggling to do right by themselves and others. It's also a paean to Chicago, my hometown ...” — Isaac Stanley-Becker, The Atlantic, 10 Aug. 2025 Did you know? In ancient Greece, Paiā́n (or Paiṓn) was a name used for the god Apollo when in the guise of physician to the gods (Paiā́n/Paiṓn comes from the name of an older Mycenaean healer god). Paiā́n and paiṓn were also used to refer to hymns of thanksgiving and praise sung especially to Apollo, as was their Latin descendant, paean. When paean first appeared in English in the late 16th century, it was used both in the context of Greek history and in general for a joyous song or hymn of praise, tribute, thanksgiving, or triumph. Over time, the word became even more generalized, and it is now used for any kind of tribute.

Merriam-Webster's Word of the Day for February 28, 2026 is: congruous • \KAHNG-groo-us\  • adjective Something described as congruous is in agreement, harmony, or correspondence with something else. Congruous can also describe something that is appropriate for a particular circumstance or requirement, or a thing that is marked or enhanced by harmonious agreement among its constituent elements. // Their professional achievements were congruous with their academic abilities. // The low bookshelf forms a congruous barrier between the spaces. // It is a congruous, plausible story, consistent in all its details. See the entry > Examples: “Hannah is a sustainability consultant and climate impact manager, which is congruous with an outdoor ethos and the culture around bike guiding ...” — Wendy Altschuler, Forbes, 3 Sept. 2024 Did you know? Congruous had only been part of the English language for a few decades in 1615, when a book about the Church of Rome referred to “teaching most congruous to reason.” The word has remained more or less true to its Latin roots: it comes from Latin congruus, an adjective that comes from the verb congruere, meaning “to come together” or “to agree.” (Its more common antonym, incongruous is about the same age.) Another familiar congruere descendant in English is congruent, which first appeared at least a century earlier with the same meaning as congruous. English also acquired congrue, a verb meaning “to be in harmony” or “to agree,” from congruere, but it has since become obsolete.

Merriam-Webster's Word of the Day for February 27, 2026 is: nettle • \NET-ul\  • verb To nettle someone is to make them angry or annoyed. // Though he tried to maintain a friendly tone, the town official was clearly nettled by the reporter's suggestion that the town was at fault. See the entry > Examples: "I can't help but be reminded of an idiom that irked me no end during times of familial stress ... : 'Use it or lose it.' The message being that if a skill or resource is not regularly utilised, over time, we will lose it. As nettled as I was by it, I now feel obliged to acknowledge the obvious truth behind the catchphrase." — Gwen Loughman, The Journal (Ireland), 21 Aug. 2025 Did you know? If you've ever brushed against nettles, you know those plants have sharp bristles that can leave you smarting and itching. The painful and irritating rash that nettles cause can last for days, but at least it is a rash with a linguistic silver lining. The discomfort caused by nettles can serve to remind one that the verb nettle is a synonym of irritate. Nettle originated as a plant name that we can trace to the Old English word netel. Eventually, people likened the persistent stinging itch caused by the plant to the nagging aggravation of being annoyed, and nettle joined the likes of vex, peeve, and irk in describing such little miseries.

Merriam-Webster's Word of the Day for February 26, 2026 is: knackered • \NAK-erd\  • adjective Knackered is an adjective mostly used informally in British English to mean “very tired or exhausted.” // Unfortunately, I was too knackered after work to join them for dinner. See the entry > Examples: “‘How are you doing?’ ‘Yeah, good thanks... just tired.’ I don’t know about you, but it feels like I’m having a version of this exchange at least once a day. It seems that everyone I know is genuinely and profoundly knackered. My friends say it. My postman says it. My teenage son says it. Even my partner, who usually has the energy levels of a Duracell-powered soft toy, grudgingly admits his batteries are drained.” — Sara Robinson, The Western Mail (Cardiff, Wales), 22 Nov. 2025 Did you know? An apt synonym for knackered might be the phrase “dead tired” for more than one reason. Knackered is a 20th century coinage that comes from the past participle of knacker, a slang term meaning “to kill,” as well as “to tire, exhaust, or wear out.” This verb knacker likely comes from an older noun knacker, which first referred to a harness-maker or saddlemaker, and later to a buyer of animals no longer able to do farmwork (or their carcasses). Knackered is used on both sides of the Atlantic but is more common among British speakers.

Merriam-Webster's Word of the Day for February 25, 2026 is: onomatopoeia • \ah-nuh-mah-tuh-PEE-uh\  • noun Onomatopoeia refers to the creation of words that imitate natural sounds. It can also refer to the words themselves, such as buzz and hiss. // The author’s clever use of onomatopoeia delights children especially. See the entry > Examples: “As they began to slurp, columns of noodles steadily streamed upward into their open jaws. The jazz soundtrack of Hiromi’s Sonicwonder playing ‘Yes! Ramen!!’ was punctuated by a gurgling roar reminiscent of shop vacs inhaling shallow pools. ‘We call it ‘hitting the zu’s,’’ says Steigerwald, noting the reference to zuru zuru, the onomatopoeia for slurping ramen in Japanese comics.” — Craig LaBan, The Philadelphia Inquirer, 18 Jan. 2026 Did you know? English speakers have only used the word onomatopoeia since the 1500s, but people have been creating words that imitate the sounds heard around them for much longer; chatter, for example, dates to the 1200s. Some onomatopes (as onomatopoeic words are sometimes called) are obvious—fizz, jingle, toot, and pop do not surprise. But did you know that other onomatopes include bounce, tinker, and blimp? Boom! Now you do. In fact, the presence of so many imitative words in language spawned the linguistic bowwow theory, which hypothesizes that language originated in the imitating of natural sounds. While it’s highly unlikely that onomatopoeia is the sole impetus for human language, it certainly made a mark, which is nothing to sneeze at.

Merriam-Webster's Word of the Day for February 24, 2026 is: umpteen • \UMP-teen\  • adjective Umpteen is an informal adjective meaning "very many" or "indefinitely numerous." // The artist has painted the same subject umpteen times, yet each piece has its own unique quality. See the entry > Examples: "The life of a showgirl often includes umpteen costume changes, elaborate props and copious amounts of hairspray." – The Economist, 4 Oct. 2025 Did you know? There may not be a gazillion ways in English to refer to a large, indefinite number, but there are definitely more than a soupçon. Many of these, such as zillion, bazillion, kazillion, jillion, and bajillion, start with -illion (as in million) and add a satisfying consonant or syllable in front for some extra oomph. The adjective umpteen does the same for -teen, with the oomph provided by the ump in umpty. Umpty, an adjective meaning "such and such" (as in "umpty percent" or "umpty-four") arose, like umpteen, in the latter half of the 1800s. We only occasionally use umpty these days, but you're bound to hear or read umpteen and umpteenth ("latest or last in an indefinitely numerous series") any number of times.

Merriam-Webster's Word of the Day for February 23, 2026 is: culminate • \KUL-muh-nayt\  • verb To culminate is to reach the end or the final result of something. Culminate is usually used with in or with. // Their efforts have culminated in the discovery of a new treatment. See the entry > Examples: “The grand emotions of these cartoons-come-to-life culminate in huge song and dance numbers, the songs sung by the voices you know and love from the movies and the dances enhanced by the grace of topflight figure skating.” — Christopher Arnott, The Hartford Courant, 11 Jan. 2026 Did you know? When a star or other heavenly body culminates, it reaches its highest point above the horizon from the vantage point of an observer on the ground. The English verb culminate was drawn (via Medieval Latin) from the Late Latin verb culminare, meaning “to crown,” specifically for this astronomical application. Its ultimate root is the Latin noun culmen, meaning “top.” Today, the word’s typical context is less lofty: it can mean “to reach a climactic point,” as in “a long career culminating in a prestigious award,” but it can also simply mean “to reach the end of something,” as in “a sentence culminating in a period.”

Merriam-Webster's Word of the Day for February 22, 2026 is: foray • \FOR-ay\  • noun A foray is an initial and often hesitant attempt to do something in a new or different field or area of activity, as in “the novelist’s foray into nonfiction.” In martial contexts, foray means “a sudden or irregular invasion or attack for war or spoils.” // The professional wrestler’s surprise foray into ballet was at first met with skepticism, but he eventually proved himself a dancer of grace and poise. See the entry > Examples: “Bryan Escareño’s foray into fashion was the result of happenstance. In 2018, the designer, who was born and raised in Venice, California, bought a green vintage Singer sewing machine at a garage sale determined to learn to make the perfect pair of denim pants. … He began honing his sewing skills, eventually crafting cut-and-sew flannel shirts that caught the eye of his colleagues at LA’s Wasteland, a high-end resale boutique.” — Celia San Miguel, USA Today, 3 Dec. 2025 Did you know? For centuries, foray referred only to a sudden or irregular invasion or attack, but in the late 19th century it began to venture into gentler semantic territory. While the newer sense of foray still involves a trek into a foreign territory, the travel is figurative: when you make this kind of foray, you dabble in an area, occupation, or pastime that’s new to you. Take the particularly apt example (stay tuned) of mushroom hunting. The likely ancestor of foray is an Anglo-French word referring to the violent sort who do invasion forays, but that word could also refer to a forager—that is, one who wanders in search of food. (Forage has the same etymological source.) Interestingly, foray has seen a resurgence of use connected to its foraging roots, as evidenced by the growing popularity of mycophile-led mushroom “forays” that have been lately popping up like toadstools.

Merriam-Webster's Word of the Day for February 21, 2026 is: laconic • \luh-KAH-nik\  • adjective Laconic describes someone or something communicating with few words. Laconic can more narrowly mean "concise to the point of seeming rude or mysterious." // The stand-up comedian is known for his laconic wit and mastery of the one-liner. See the entry > Examples: "Elijah did not enjoy all my choices. ... But my son listened closely to every selection. He remembered plot points better than I did and assessed historical figures concisely. 'Mean,' he said of Voltaire. 'Creepy,' summed up Alexander Hamilton. ... Most surprising, my laconic teenager shared my love of Austen. Those hours listening to Pride and Prejudice were some of the happiest of my parenting life." — Allegra Goodman, LitHub.com, 4 Feb. 2025 Did you know? We'll keep it brief. Laconia was once an ancient province in southern Greece. Its capital city was Sparta, and the Spartans were famous for their terseness of speech. Laconic comes to us by way of the Latin word laconicus ("Spartan") from the Greek word lakōnikos. In current use, laconic means "terse" or "concise to the point of seeming rude or mysterious," and thus recalls the Spartans' tight-lipped taciturnity.

Merriam-Webster's Word of the Day for February 20, 2026 is: encapsulate • \in-KAP-suh-layt\  • verb Encapsulate literally means “to enclose in or as if in a capsule,” but the word is more often used figuratively as a synonym of summarize, to talk about showing or expressing a main idea or quality in a brief way. // Can you encapsulate the speech in a single paragraph? // The first song encapsulates the mood of the whole album. // The contaminated material should be encapsulated and removed. See the entry > Examples: “While choosing a single film to encapsulate a quarter-century of cinema is an impossible task, Bong Joon Ho’s dark comedy certainly belongs in the conversation. A scathing satire that links two families of vastly different means, the film’s stars thinly smile through the indignities and social faux pas before a climactic and inevitable eruption of violence.” — Kevin Slane, Boston.com, 2 Jan. 2026 Did you know? We’ll keep it brief by encapsulating the history of this word in just a few sentences. Encapsulate and its related noun, capsule, come to English (via French) from capsula, a diminutive form of the Latin noun capsa, meaning “box.” (Capsa also gave English the word case as it refers to a container or box—not to be confused with the case in “just in case,” which is a separate case.) The earliest examples of encapsulate are for its literal use, “to enclose something in a capsule,” and they date to the late 19th century. Its extended meaning, “to give a summary or synopsis of something,” plays on the notion of a capsule being something compact, self-contained, and often easily digestible.

Merriam-Webster's Word of the Day for February 19, 2026 is: syllogism • \SIL-uh-jiz-um\  • noun Syllogism refers to a formal argument in logic that is formed by two statements and a conclusion which must be true if the two statements are true. // An example of a syllogism is “All men are mortal; no gods are mortal; therefore no men are gods.” See the entry > Examples: “The Dallas area was a hotbed of competitive debate, and, at first, the oratorical polish of [Rebecca F.] Kuang’s teammates was intimidating. She spent months being coached on the art of the syllogism, a kind of logical argument in which one deduces a conclusion from a set of premises. ‘The idea that you could take something that seemed up to personal charisma or rhetorical choice and map it to this very rigid, argumentative structure was mind-blowing,’ she said.” — Hua Hsu, The New Yorker, 25 Aug. 2025 Did you know? For those trained in formal argument, the syllogism is a classical form of deduction, specifically an argument consisting of a major and a minor premise and a conclusion. One example is the inference that “kindness is praiseworthy” from the premises “every virtue is praiseworthy” and “kindness is a virtue.” Syllogism came to English through Anglo-French from the Latin noun syllogismus, which in turn can be traced back to the Greek verb syllogizesthai, which combines logizesthai (meaning “to calculate,” and coming from logos, meaning “word” or “reckoning”) with syl-, which comes from syn-, meaning “with” or “together.”

Merriam-Webster's Word of the Day for February 18, 2026 is: Goldilocks • \GOHL-dee-lahks\  • adjective Goldilocks describes something that has or produces an optimal balance usually between two extremes. In astronomy, it specifically designates an area of planetary orbit neither too hot nor too cold to support life. // The couple, undecided between country and city living, took the Goldilocks option and moved to a bustling college town surrounded by nature. See the entry > Examples: "It's a well-known fact that the time between 3 and 5 o'clock in the afternoon is a liminal space. ... It's too late for lunch, too early for dinner. But it's the Goldilocks hour for a little treat." — Nikita Richardson, The New York Times, 8 May 2025 Did you know? English has always drawn inspiration from fables and fairy tales, stories bursting with metaphors that help users get their verbiage just right: one may fall down a rabbit hole (thank you, Alice's Adventures in Wonderland), cry wolf (we see you, Aesop's Fables), or hope one day to meet one's Prince Charming (brava, Cinderella). The adjective Goldilocks is borrowed, of course, from Goldilocks and the Three Bears, a perennial favorite in which a little girl so-named for her golden hair finds the perfect balance between hot and cold, soft and hard, small and large—all in the home of unknowing strangers. Since the mid-1960s, English speakers have applied Goldilocks to all things regarded as perfectly balanced or happily medium. The word has specific applications in astronomy, with the phrase "Goldilocks zone" designating an area of planetary orbit in which temperatures are neither too hot nor too cold to support life.
