Merriam-Webster’s Word of the Day

Merriam-Webster's Word of the Day for April 26, 2025 is:

nonchalant • \nahn-shuh-LAHNT\  • adjective

Someone described as nonchalant is relaxed and calm, either because they do not care about something or because they are not worried about something. Nonchalant can also be used to describe something, such as demeanor or behavior, that expresses such relaxed, calm unconcern.

// The team showed a somewhat nonchalant attitude at the beginning of the season, but they became more serious once the championship was within reach.

Examples:

"He is largely unaffected by the fame and fortune and all the talk of greatness tends to be greeted with a nonchalant shrug." — The Evening Times (Glasgow, Scotland), 19 Mar. 2024

Did you know?

Since nonchalant ultimately comes from words meaning "not" and "be warm," it's no surprise that the word is all about keeping one's cool. Nonchalant’s Old French ancestor is the verb nonchaloir, meaning "to disregard," which combines non-, meaning "not," with chaloir, meaning "to concern." Chaloir in turn traces back to the Latin calēre, meaning "to be warm" (calēre is also the forerunner of the heat-related English word calorie). You might assume that the prefix non- implies the existence of an antonymous chalant, but no such word has developed in English. It’s no big deal though—if you want a word that means the opposite of nonchalant, both concerned and interested can do the job.

Merriam-Webster's Word of the Day for April 25, 2025 is:

travail • \truh-VAIL\  • noun

Travail is a formal word, usually used in plural, that refers to a difficult experience or situation.

// The book describes the political travails of the governor during her first year in office.

See the entry >

Examples:

"Written by Samy Burch, the film [Coyote vs. Acme] follows the travails of the desert denizen who is tired of being slammed with Acme products as he tries to outsmart the Roadrunner. Coyote finally decides to hire a lawyer to take the Acme Corp. to court for product liability, such as faulty rocket skates and defective aerial bombs." — Meg James, The Los Angeles Times, 20 Mar. 2025

Did you know?

Travail traces back to trepalium, a Late Latin word for an instrument of torture. We don't know exactly what a trepalium looked like, but the word's history gives us an idea. Trepalium comes from the Latin adjective tripalis, which means "having three stakes" (from tri-, meaning "three," and palus, meaning "stake"). Trepalium eventually led to the Anglo-French verb travailler, meaning "to torment" but also, more mildly, "to trouble" and "to journey." The Anglo-French noun travail was borrowed into English in the 13th century, along with another descendant of travailler, travel.

Merriam-Webster's Word of the Day for April 24, 2025 is:

ostensible • \ah-STEN-suh-bul\  • adjective

Ostensible is used to describe something that seems or is said to be true or real, but is possibly not true or real. In other words, it is plausible rather than demonstrably true or real.

// The ostensible purpose of a filibuster is to extend debate, but in reality it is used to delay or prevent action.

See the entry >

Examples:

“No drums, no bass, no conventional song structures: Hosianna Mantra was a 40-minute contemplation of the cosmos and cosmic love, couched in words and sounds that explicitly linked it to humanity’s grandest and most consistent way of considering meaning, religion. The ostensible polytheism conveyed by the name and the concept were only ways to realize how little we actually know, and how much we wager through mere survival.” — Grayson Haver Currin, Pitchfork, 19 Jan. 2025

Did you know?

British philosopher and economist Jeremy Bentham once wrote to Indian religious leader Ram Mohan Roy asking him to “send me two letters—one confidential, another ostensible.” By ostensible he meant that, unlike the confidential letter, the latter was intended to be shown to people other than Bentham himself. This sense of ostensible shows clearly the influence of the word’s Latin ancestor, the verb ostendere, meaning “to hold out for inspection,” “to show,” “to make clear by one’s actions,” and “to demonstrate.” Ostensible is still used today as it is in Bentham’s letter, but it is much more likely to suggest a discrepancy between a declared or implied aim or reason (i.e., the aim or reason that someone displays or “shows” to others) and the true one. For example, someone might give “seeing an old friend” as their ostensible reason for planning a trip when in reality they are planning on spending most of their time relaxing on the beach.

Merriam-Webster's Word of the Day for April 23, 2025 is:

slough • \SLUFF\  • verb

Slough is a formal verb used for the action of getting rid of something unwanted. It is usually used with off. Slough can also mean "to lose a dead layer of (skin)" or "to become shed or cast off."

// The editorial urges the mayor not to slough off responsibility for the errors in the report.

// The exfoliating cleanser promises to gently slough away dead skin cells.

Examples:

"Before she left her apartment, she gathered and washed some in a bowl. Then she drew a bath and soaked for a while, eating the figs one by one, swallowing even the hard stems. The steam and water loosened her tense muscles, and her aches started to vanish. She scrubbed herself until the dead skin sloughed off, and underneath, she was new." — Sally Wen Mao, Ninetails: Nine Tales, 2024

Did you know?

There are two verbs spelled slough in English, as well as two nouns, and both sets have different pronunciations. The first noun, referring to a swamp or a discouraged state of mind, is pronounced to rhyme with either blue or cow. Its related verb, which can mean "to plod through mud," has the same pronunciation. The second noun, pronounced to rhyme with cuff, refers to the shed skin of a snake (as well as anything else that has been cast off). Its related verb describes the action of shedding or eliminating something, just like a snake sheds its skin. This slough comes from Middle English slughe and is related to slūch, a Middle High German word meaning "snakeskin."

Merriam-Webster's Word of the Day for April 22, 2025 is:

liaison • \lee-AY-zahn\  • noun

Liaison refers to a person who helps organizations or groups work together and provide information to each other, or to a relationship that allows such interactions. Liaison can also refer to an illicit sexual relationship.

// The new position involves acting as a liaison between the police department and city schools.

// The committee has maintained close liaison with some of the former board members.

Examples:

“In 2019, [Jefri] Lindo found work at Bestia, the trendy downtown restaurant. ... He flourished there, working his way up to house expeditor, acting as the key liaison between the kitchen and dining room.” — Laura Tejeda, The Los Angeles Times, 27 Feb. 2025

Did you know?

If you took French in school, you might remember that liaison is the word for the phenomenon that causes a silent consonant at the end of one word to sound like it begins the next word when that word begins with a vowel, so that a phrase like beaux arts sounds like \boh zahr\. We can thank French for the origin of the term liaison, as well. It comes from Middle French lier, meaning “to bind or tie.” Other English senses of liaison apply it to all kinds of bonds—from binding and thickening agents used in cooking (as in “a butter and flour liaison”), to people who work to connect different groups, to the kind of secret relationship sometimes entered into by two people who are romantically attracted to one another.

Merriam-Webster's Word of the Day for April 21, 2025 is:

bodacious • \boh-DAY-shuss\  • adjective

Bodacious is used as an informal synonym of remarkable and noteworthy, as well as sexy and voluptuous. In some dialects of the Southern and Midland US, bodacious is used by its oldest meaning: "outright, unmistakable."

// The bodacious decor of the boutique hotel is intended to appeal to the young and the hip.

See the entry >

Examples:

"There’s no need to lug in a 6-foot specimen tree to add bodacious botanicals into your home, because even the smallest planters can make a big impact when intentionally pairing striking foliage with a unique vessel." — Kristin Guy, Sunset Magazine, 5 Mar. 2024

Did you know?

Some of our readers may know bodacious as a word that figured prominently in the lingo of the 1989 film Bill and Ted's Excellent Adventure. Others may recall the term's frequent use in the long-running "Snuffy Smith" comic strip. Neither the creators of the comic strip nor the movie can claim to have coined bodacious, which began appearing in print in the mid-1800s, but both surely contributed to its popularity. The exact origin of the word is uncertain, but it is most likely a blend of bold and audacious, and it may be linked to boldacious, a now-rare British dialect term meaning "brazen" or "impudent."

Merriam-Webster's Word of the Day for April 20, 2025 is:

resurrection • \rez-uh-REK-shun\  • noun

In Christian theology, Resurrection (typically capitalized in this use) refers to the event in which Jesus Christ returned to life after his death. In general contexts, resurrection refers to the act of causing something that had ended or been forgotten or lost to exist again, to be used again, etc.

// Church members look forward to celebrating the Resurrection every Easter.

// The community applauded the resurrection of the commuter rail system.

See the entry >

Examples:

“Some of their efforts to follow Scripture were wonderfully zany. To wrest the death and resurrection of Jesus away from both pagan fertility rituals and Hallmark, they outlawed Easter egg hunts. ... She smashed chocolate Easter bunnies with a meat tenderizer and ripped the heads off marshmallow Peeps, while the boys gleefully gobbled the ruined remnants of consumer culture.” — Eliza Griswold, Circle of Hope: A Reckoning with Love, Power, and Justice in an American Church, 2024

Did you know?

The word resurrection first arose in English in the 14th century, coming from the Anglo-French word resurreccioun, which in turn comes from the Late Latin verb resurgere, meaning “to rise from the dead.” Originally, the word was used in Christian contexts to refer to the rising of Christ from the dead or to the festival celebrating this rising (now known as Easter). Perhaps showing the influence of the Late Latin verb resurgere’s Latin forerunner, which could mean “to rise again” (as from a recumbent position) as well as “to spring up again after being cut” (used of plants), resurrection soon began to be used more generally in the senses of “resurgence” or “revival.” It even forms part of the name of the resurrection fern, an iconic fern of the southern United States often seen growing on the limbs of live oak trees. The fern is so named due to the fact that in dry weather it curls up, turns brown, and appears dead, only to be “brought back to life” when exposed to moisture.

Merriam-Webster's Word of the Day for April 19, 2025 is:

fastidious • \fass-TID-ee-us\  • adjective

Someone described as fastidious is extremely or overly careful about how they do something. Fastidious may also describe someone who is difficult to please, or someone who always wants to be clean, neat, etc.

// Our parents taught us to be fastidious in keeping our rooms clean, making sure to dust every surface and sweep out every corner.

// He's a fastidious dresser whose fashion choices seem to anticipate the newest trends.

Examples:

"Becoming Led Zeppelin, filmmaker Bernard MacMahon's new documentary about the band, certainly succeeds at taking Led Zeppelin seriously, in ways that might disappoint some viewers but that I found both compelling and refreshing. Becoming Led Zeppelin doesn't hide that it's an authorized biopic … but the film is so fastidious and detail-oriented that it never feels like hagiography." — Jack Hamilton, Slate, 11 Feb. 2025

Did you know?

If you presume that the adjective fastidious bears some relation to fast, not so fast. Fastidious comes from Latin fastidium, meaning "aversion" or "disgust." Fastidium is believed to be a combination of fastus, meaning "arrogance," and taedium, "irksomeness" or "disgust." (Taedium is also the source of tedium and tedious.) In keeping with its Latin roots, fastidious once meant "haughty," "disgusting," and "disagreeable," but the word is now most often applied to people who are very meticulous or overly difficult to please, or to work which reflects a demanding or precise attitude. Our own fastidiousness requires us to point out that the familiar adjective fast comes not from Latin, but from Old English.

Merriam-Webster's Word of the Day for April 18, 2025 is:

collaborate • \kuh-LAB-uh-rayt\  • verb

To collaborate is to work with another person or group in order to do or achieve something. Collaborate can also be used disapprovingly to mean "to cooperate with or willingly assist an enemy of one's country and especially an enemy who occupies it during a war."

The 17-piece display delivers deeply personal pieces intimately connected to Jones' artistic journey. Known for his striking photography and poetry, Jones extends a unique invitation to the viewer, allowing them to immerse themselves in the intricate layers of his art." — Kenyatta Victoria, Essence, 1 May 2024

Did you know?

The Latin prefix com-, meaning "with, together, or jointly," is a bit of a chameleon—it has a habit of changing its appearance depending on what it's next to. For example, if the word it precedes begins with l, com- becomes col-. In the case of collaborate, com- teamed up with the verb laborare ("to labor") to form the Late Latin word collaborare ("to labor together"). Be careful not to confuse collaborate with corroborate, another com- relative. This word was formed when com- (this time shape-shifting to cor-) joined forces with the Latin word robur ("strength"). Together, by way of the Latin verb corroborare, they created the meaning "to support or help prove (a statement, theory, etc.) by providing information or evidence," which carried over into the English word corroborate.

Merriam-Webster's Word of the Day for April 17, 2025 is:

uncouth • \un-KOOTH\  • adjective

Uncouth describes things, such as language or behavior, that are impolite or socially unacceptable. A person may also be described as uncouth if they are behaving in a rude way.

// Stacy realized it would be uncouth to show up to the party without a gift, so she picked up a bottle of wine on the way.

See the entry >

Examples:

“Perhaps people deride those who buy books solely for how they look because it reminds them that despite their primary love of literature, they still appreciate a beautiful cover. It’s not of primary importance but liking how something looks in your home matters to some extent, even if it feels uncouth to acknowledge.” — Chiara Dello Joio, LitHub.com, 24 Jan. 2023

Did you know?

Old English speakers used the word cūth to describe things that were familiar to them, and uncūth for the strange and mysterious. These words passed through Middle English into modern English with different spellings but the same meanings. While couth eventually dropped out of use, uncouth soldiered on. In Captain Singleton by English novelist Daniel Defoe, for example, the author refers to “a strange noise more uncouth than any they had ever heard,” while Shakespeare wrote of an “uncouth forest” in As You Like It. This “unfamiliar” sense of uncouth, however, joined couth in becoming, well, unfamiliar to most English users, giving way to the now-common meanings, “rude” and “lacking polish or grace.” The adjective couth in use today, meaning “sophisticated” or “polished,” arose at the turn of the 20th century, not from the earlier couth, but as a back-formation of uncouth, joining the ranks of other “uncommon opposites” such as kempt and gruntled.
