Merriam-Webster's Word of the Day for June 6, 2025 is:

festoon • \fess-TOON\  • verb

Festoon usually means "to cover or decorate (something) with many small objects, pieces of paper, etc.," or "to appear here and there on the surface of." It can also mean "to hang decorative chains or strips on."

// Tiny wildflowers festooned the meadow.

// We festooned the halls with ribbons and garland.

Examples:

"The road was lined with ancient trees festooned with Spanish moss." — Tayari Jones, Travel + Leisure, 14 Apr. 2025

Did you know?

The noun festoon first appeared in the 1600s when it was used, as it still is today, to refer to decorative chains or strips hung between two points. (It can also refer to a carved, molded, or painted ornament representing such a chain.) After a century's worth of festoon-adorning, the verb festoon made an entrance, and people began to festoon with their festoons—that is, they draped and adorned with them. The verb form of festoon has since acquired additional, more general senses related not only to decorating, but to appearing on the surface of something, as in "a sweater festooned with unicorns." Perhaps unsurprisingly, this celebratory-sounding and party-associated word traces back (by way of French and Italian) to Latin festa, the plural of festum, meaning "festival."

Merriam-Webster's Word of the Day for June 5, 2025 is:

sea change • \SEE-CHAYNJ\  • noun

Sea change refers to a big and sudden change or transformation.

// The early 2000s witnessed a sea change in public opinion about smoking in public places.

Examples:

“Over the course of my grandmother's lifetime, gender expectations for women underwent a sea change. My grandmother ended up pursuing an education and becoming a doctor, leading an independent life that made her mother proud.” — Wendy Chen, LitHub.com, 20 May 2024

Did you know?

In The Tempest, William Shakespeare's final play, sea change refers to a change brought about by the sea: the sprite Ariel, who aims to make Ferdinand believe that his father the king has perished in a shipwreck, sings within earshot of the prince, “Full fathom five thy father lies...; / Nothing of him that doth fade / But doth suffer a sea-change / into something rich and strange.” This is the original, now-archaic meaning of sea change. Today the term is used for a distinctive change or transformation. Long after sea change gained this figurative meaning, however, writers continued to allude to Shakespeare's literal one; Charles Dickens, Henry David Thoreau, and P.G. Wodehouse all used the term as an object of the verb suffer, but now a sea change is just as likely to be undergone or experienced.

Merriam-Webster's Word of the Day for June 4, 2025 is:

bogus • \BOH-gus\  • adjective

Bogus is an informal word used to describe something that is not real or genuine, making it a synonym of such words as fake, false, and counterfeit.

// We were disappointed to find out that the purses we bought were bogus.

Examples:

“A former West Covina resident admitted to selling at least $250,000 in bogus sports and entertainment memorabilia, including forged photos and signatures of the ‘Keeping Up With the Kardashians' stars.” — Noah Goldberg, The Los Angeles Times, 9 Apr. 2025

Did you know?

In her 1840 novel A New Home—Who'll Follow?, author Carolina Kirkland wrote about a scandal affecting the fictitious frontier town of Tinkerville, whose bank vaults were discovered to contain “a heavy charge of broken glass and tenpenny nails, covered above and below with half-dollars, principally ‘bogus.' Alas! for Tinkerville, and alas, for poor Michigan!” Alas indeed. Bogus (an apparent U.S. coinage) was first used in the argot of wildcat banks (like the one in Tinkerville) as a noun referring to counterfeit money. It later branched out into adjective use meaning “counterfeit or forged.” Although the noun is now obsolete, the adjective is still used today with the same meaning, and is applied not only to phony currency but to anything that is less than genuine, making it part of a treasury of similar words ranging from the very old (sham) to the fairly new (fugazi).

Merriam-Webster's Word of the Day for June 3, 2025 is:

tutelage • \TOO-tuh-lij\  • noun

Tutelage is a formal word that refers to the instruction or guidance especially of an individual student by a teacher. Tutelage may also refer to an act or process of serving as guardian or protector.

// Under the tutelage of his high school swim coach, Luis has greatly improved his times at meets.

Examples:

"[Hercules] Mulligan helped with [Alexander] Hamilton's education, including placing him under the tutelage of William Livingston of the College of New Jersey (now Princeton University), who was a leading local American revolutionary. ... Mulligan is said to have deeply influenced Hamilton towards engagement in revolutionary activity." — Brian Maye, The Irish Times, 2 Mar. 2025

Did you know?

Tutelage comes from the Latin verb tueri, meaning "to look at" or "to guard." When it first appeared in English at the turn of the 17th century, this word was used mainly in the protective sense of tueri; writers would describe serfs and peasants of earlier eras as being "under the tutelage of their lord." Over time, however, the word's meaning shifted away from guardianship and toward instruction. This pattern of meaning can also be seen in the related nouns tutor, which shifted from "a guardian" to "a private teacher," and tuition, which now typically refers to the cost of instruction but which originally referred to the protection, care, or custody by a parent or guardian over a child or ward.

Merriam-Webster's Word of the Day for June 2, 2025 is:

Herculean • \her-kyuh-LEE-un\  • adjective

Something described as Herculean (often uncapitalized as herculean) is characterized by extraordinary power, extent, intensity, or difficulty.

// Although starting a garden sounded fun in theory, the constant weeding and pest control turned it into a herculean task.

See the entry >

Examples:

“Strong doesn't even properly describe [Ashton] Jeanty's Herculean, how-is-he-doing-that kind of strength. Before his sophomore year of college, he squatted 575 pounds. [Coach James] Montgomery thought that Jeanty had maxed out. He was wrong. Now Jeanty easily squats 605 pounds ‘like a hot knife through butter,' Montgomery says.” — Mirin Fader, The Ringer, 5 Dec. 2024

Did you know?

The hero Hercules, son of the god Zeus by a human mother, was famous for his superhuman strength. As penance for a madness-induced murder spree (the victims were his family), he was forced to perform twelve enormously difficult tasks, or “labors.” These ranged from descending into the underworld to bring back the terrifying dog that guarded its entrance to destroying the many-headed monster called the Hydra. The feats he accomplished explain how Herculean in the 16th century came to be used for any job or task that's extremely difficult or calls for enormous strength.

Merriam-Webster's Word of the Day for June 1, 2025 is:

proscribe • \proh-SCRYBE\  • verb

Proscribe is a formal word meaning “to condemn or forbid something as harmful or unlawful.” More broadly, it can mean simply “to not allow something.”

// The town has passed an ordinance that proscribes the ownership of snakes and other exotic pets.

See the entry >

Examples:

“While the order proscribes new drilling along most of both the Atlantic and Pacific coasts, the order does not affect active drilling permits and carves out the most important areas of offshore production such as the western Gulf of Mexico near Texas and Louisiana.” — Jeff Young, Newsweek, 6 Jan. 2025

Did you know?

Signs, signs, everywhere, signs: some prescribe (“do this”) and others proscribe (“don't do that”). Don't take it as a bad sign if you have difficulty telling prescribe and proscribe apart, however; you've got plenty of company, and a good excuse. Proscribe and prescribe both come from Latin words that combine a prefix meaning “before” with the verb scribere, meaning “to write.” Yet the two words have very distinct, often nearly opposite meanings, hints of which emerge upon a closer look at their origins. Prescribe comes from praescribere, meaning “to dictate, order”—clear enough for a word used when making rules and giving orders. Proscribe has a more complex history: proscribere means both “to publish” and, more specifically, “to publish the name of someone who is condemned to death and whose property is now forfeited to the state.” This narrower meaning is the one proscribe carried into English when it was first used in the 15th century. By the early 17th century, the word had expanded from merely signaling condemnation to actual condemning or prohibiting.

Merriam-Webster's Word of the Day for May 31, 2025 is:

opportune • \ah-per-TOON\  • adjective

Opportune describes something that is suitable or convenient for a particular situation, or that is done or happening at an appropriate time.

// They chose an opportune time to invest in real estate.

// She is waiting for an opportune moment to ask for a raise.

Examples:

“It [the Mystic Seaport Museum in Connecticut] was constructed on the site of an 1830s shipyard built by three mariner brothers, George, Clark, and Thomas Greenman. They, like other entrepreneurs in the booming seafaring community of Mystic, took over low-lying and marshy lands whose gently sloping banks and proximity to the Atlantic Ocean were opportune for shipbuilding.” — Annabel Keenan, The New York Times, 22 Apr. 2025

Did you know?

If you've never had the opportunity to learn the history behind opportune, now's your chance. Both opportune and opportunity come from Latin opportūnus, which can mean “favoring one's needs,” “serviceable,” or “convenient.” Opportūnus itself, constructed from the prefix ob-, meaning “to,” portu- (stem of the noun portus, meaning “port” or “harbor”), and the adjective suffix -nus, suggests the value of any port available when a storm is brewing or raging. Portus has dropped anchor in other English words as well, including portal, passport, and of course port. Its footprint is also scattered across our maps in coastal place names, from Newport to Puerto Rico to Porto Alegre.

Merriam-Webster's Word of the Day for May 30, 2025 is:

gust • \GUST\  • noun

Gust refers to a sudden strong wind. It is also used figuratively for a sudden outburst of something, such as a feeling.

// Today's weather will be windy, with gusts of up to 40 miles per hour.

See the entry >

Examples:

“This subversive comedy is now a posh panto, directed by Max Webster. It gets gusts of laughter but can feel rather forced, and the joyous language is left to fend for itself.” — Robert Gore-Langton, The Mail on Sunday (London), 8 Dec. 2024

Did you know?

You're no doubt familiar with the breezy gust meaning “a brief burst of wind.” But about a century and a half before that word first appeared in print in the late 16th century, a different gust blew onto the scene. The windy gust likely comes from a synonymous Old Norse word, gustr, whereas the older gust, which refers to the sensation of taste as well as to a feeling of enthusiastic delight, comes ultimately from gustus, the Latin word for “taste.” English speakers eventually mostly dropped that older gust, replacing it in the early 17th century with a similar gustus word borrowed from Italian: gusto is now the go-to word when you want to refer to enthusiastic and vigorous enjoyment or appreciation. You can use it with gusto.

Merriam-Webster's Word of the Day for May 29, 2025 is:

nascent • \NASS-unt\  • adjective

Nascent is a formal word used to describe something that is just beginning to exist, or in other words, is recently formed or developed.

// The actress is now focused on her nascent singing career.

See the entry >

Examples:

“I asked my father, recently, if I might borrow one of his old journals as research for a nascent writing project. It felt like there might be something there—in the poetry of varietal names (Beedy's Camden Kale, Ruby Perfection Cabbage), or the steady plotless attention to the natural world.” — Fiona Warnick, LitHub.com, 9 May 2024

Did you know?

Nascent descends from the Latin verb nasci, meaning “to be born,” as does many an English word, from nation and nature to innate and renaissance. But rather than describing the birth of literal babies—as in pups, kits, hoglets, et al.—nascent is applied to things (such as careers or technologies) that have recently formed or come into existence, as when scholar Danille K. Taylor-Guthrie wrote of Toni Morrison being “an integral part of a nascent group of black women writers who would alter the course of African American, American, and world literature.”

Merriam-Webster's Word of the Day for May 28, 2025 is:

fiasco • \fee-ASK-oh\  • noun

A fiasco is a complete failure or disaster.

// The entire fiasco could have been avoided if they'd simply followed the instructions.

See the entry >

Examples:

"Fyre's first iteration, in 2017, was widely seen as a massive failure. The luxe accommodations promised on the Bahamian island of Great Exuma turned out to be tents and instead of the promised gourmet fare, guests were served cold cheese sandwiches. After musical acts bailed at the last minute, attendees were left stranded as organizers canceled the festival entirely. The fiasco resulted in at least two documentaries." — Theresa Braine, The Sentinel & Enterprise (Fitchburg, Massachusetts), 24 Feb. 2025

Did you know?

English speakers picked up fiasco from the French, who in turn adopted it from the Italian phrase fare fiasco—literally, "to make a bottle." Just what prompted the development of the meaning "failure" from "bottle" has remained obscure. One guess is that when a Venetian glassblower would discover a flaw developing in a beautiful piece they were working on, they would turn it into an ordinary bottle to avoid having to destroy the object. The bottle would naturally represent a failure to the glassblower, whose would-be work of art was downgraded to everyday glassware. This theory, however, remains unsubstantiated.
