Merriam-Webster's Word of the Day for June 11, 2026 is:

saturnine • \SAT-er-nyne\  • adjective

Saturnine is a literary word that typically describes people who are glum and grumpy, or things that suggest or express gloom. It can also mean “slow to act or change.”

// A walk in the sunshine can improve your mood significantly, raising the spirits of even the most saturnine among us.

Examples:

“If he was once more cautious in interviews, coming across as a little saturnine, he’s looser now, illuminated by flashes of wry humour.” — Patrick Smith, The Independent (United Kingdom), 1 Feb. 2026

Did you know?

Saturnine is far—even astronomically far—from the cheeriest of words. It has a long history of describing the glum and grouchy among us, and comes ultimately from Sāturnus, name of the Roman god of agriculture, who was often depicted as a bent old man with a stern, sluggish, and sullen nature. Saturn, the ringed gas giant that is one of five planets visible to the naked eye, is of course the namesake of Sāturnus, and Saturn does indeed seem to dawdle; it requires over 29 of our Earth years to orbit the sun. The ancient Romans (like some astrologers today) believed those who are born when Saturn is rising in the sky tend toward being a Gloomy Gus or Debbie Downer. We don’t know A. A. Milne’s take on the influence of Saturn, but his gloomy, cynical gray donkey Eeyore is famously saturnine, a fact Eeyore himself would surely stoically accept as true if it were pointed out to him.

Merriam-Webster's Word of the Day for June 10, 2026 is:

foible • \FOY-bul\  • noun

Foibles are minor flaws or shortcomings in someone's character or behavior. In fencing, foible refers to the weakest part of a sword's blade, between the middle and point.

// You have to be able to laugh at your own foibles.

See the entry >

Examples:

"The British sketch comedy troupe Monty Python loved taking aim at contemporary foibles through its twisted and liberal reading of history." — David Faris, The Week, 29 Apr. 2026

Did you know?

Many word lovers agree that the pen is mightier than the sword. But be they honed in wit or form, even the sharpest tools in the shed have their flaws. That’s where foible comes in handy. Borrowed from French in the 1600s, the word originally referred to the weakest part of a fencing sword, that part being the portion between the middle and the pointed tip. The English foible soon came to be applied not only to weaknesses in blades but also to minor failings in character. Foible ultimately traces back to the Old French term feble, which is also the source of our English adjective feeble.

Merriam-Webster's Word of the Day for June 9, 2026 is:

deleterious • \del-uh-TEER-ee-us\  • adjective

Deleterious is a word used in formal speech and writing to describe something that is damaging or harmful, usually in a subtle or unexpected way.

// Though effective at keeping pests away from plants, the spray is no longer used because of its deleterious effects on the respiratory system.

See the entry >

Examples:

“Canceling email addresses used by alumni over many years could have deleterious consequences for professional networking, which will become increasingly important as the AI roll-out accelerates and disrupts careers for thousands of college graduates.” — William Golz, NOLA.com (New Orleans, Louisiana), 15 Apr. 2026

Did you know?

When you hold down the delete key on your keyboard or touchscreen, the effect—whoosh!—is instantaneous. Deleterious effects, however, are often not so obvious; deleterious (ultimately from a Greek word meaning “to hurt”) is used to describe things that are harmful in ways that are unexpected, slow-acting, or not readily apparent. Although most often used in formal speech and writing, deleterious is far from rare. It even pops up from time to time in film and television, especially from the mouths of wonky characters, as when Seven of Nine warns the Doctor in an episode of Star Trek Voyager, “The nebula is having a deleterious effect on all the ship’s technology,” or when Higgins exclaims in the original Magnum P.I. series, “It’s shocking what a deleterious effect a regimen of nothing but mushrooms can have on a man.” We’ll take your word for it, Higgins.

Merriam-Webster's Word of the Day for June 8, 2026 is:

accoutrement • \uh-KOO-truh-munt\  • noun

An accoutrement is a piece of clothing or equipment that is used in a particular place or for a particular activity. In military contexts, accoutrement refers specifically to a soldier's outfit. The word can also refer to an identifying and often superficial characteristic or device. Accoutrement in any of its uses is often pluralized.

// They have all the accoutrements that a baker could ever want, including a robust collection of cookie cutters and a veritable wardrobe of vintage aprons.

See the entry >

Examples:

"From the spectacularly colorful Parade of Flags ... to the customary dress and cultural accoutrements of the nations, we see just how rich, varied and wonderful are the backgrounds of these students who have traveled far to study among us." – The Commercial Dispatch (Columbus, Mississippi), 14 Apr. 2026

Did you know?

Accoutrement and its rarer relative accoutre, a verb meaning "to provide with equipment or furnishings" or "to outfit," have been appearing in English texts since the 16th century. Today both words have variant spellings—accouterment and accouter, respectively. The pair's French ancestor, accoutrer, descends from an Old French word meaning "to put in place" and may ultimately trace back to the Latin word consuere, meaning "to sew together." Some etymological stitching is visible in another English word: couture, a word referring to the business of making fashionable clothes, as well as to the clothes themselves, is a direct French borrowing that ultimately descends from consuere.

Merriam-Webster's Word of the Day for June 7, 2026 is:

MacGyver • \muh-GHYE-ver\  • verb

To MacGyver something is to make, form, or repair it with materials that are conveniently on hand.

// Social media websites are full of videos that show people MacGyvering everything from a life jacket out of a pair of pants to a stove using three metal cans and some dirt.

See the entry >

Examples:

“Maybe your shovel broke the first time you tried to clear wet, heavy snow off your sidewalk and you never replaced it. ... Of course, before you start MacGyvering a shovel from spare parts in your garage, you can ask a neighbor for assistance or make a few phone calls and pay for a service to clear your driveway or sidewalks.” — Caroline Anschutz, SlashGear.com, 28 Jan. 2026

Did you know?

Angus MacGyver, as portrayed by actor Richard Dean Anderson in the titular, action-packed television series MacGyver, was many things—including a secret agent, a Swiss Army knife enthusiast, and a convert to vegetarianism—but he was no MacGuffin (a character that keeps the plot in motion despite lacking intrinsic importance). In fact, so memorable was this man, his mullet, and his ability to use whatever was available to him—often simple things, such as a paper clip, chewing gum, or a rubber band—to escape a sticky situation or to make a device to help him complete a mission, that people began associating his name with making quick fixes or finding innovative solutions to immediate problems. Hence the verb MacGyver, a slang term meaning to “make, form, or repair (something) with what is conveniently on hand.” After years of steadily increasing and increasingly varied usage following the show’s run from 1985 to 1992 (tracked in some detail here), MacGyver was added to our online dictionary in 2022.

Merriam-Webster's Word of the Day for June 6, 2026 is:

valedictory • \val-uh-DIK-tuh-ree\  • adjective

Valedictory describes something expressing or containing a farewell.

// The valedictory speech given by the department chair moved several faculty members to tears.

See the entry >

Examples:

“Did I regret not catching a retrospective showing of ‘Little Miss Sunshine,’ in a special valedictory program of Sundance sensations from over the years? Perhaps—though not as much as I regretted missing the screening of Ryan Fleck and Anna Boden’s ‘Half Nelson’ (2006). That’s the title that I remember most fondly from my first year at Sundance ...” — Justin Chang, The New Yorker, 31 Jan. 2026

Did you know?

Valedictory addresses delivered by valedictorians at high school and college graduations are as much a sign of spring in the United States as baseball games and cookouts. Though we don’t know where the first valedictory address was given, we do know that such addresses were an institution at some colleges in the U.S. by the time Noah Webster wrote his famous 1828 dictionary. (We also know that valedictory was used in non-academic settings—mostly churches, and especially in the phrase “valedictory sermon”—from the mid-1600s.) Since a valedictory speech is given at the end of an academic career, it is perfectly in keeping with the meaning of its Latin ancestor, valedīcere, which means “to say goodbye.”

Merriam-Webster's Word of the Day for June 5, 2026 is:

interloper • \in-ter-LOH-per\  • noun

An interloper is a person who intrudes in a place or sphere of activity; they are not wanted or welcome by the other people present.

// Summer residents were regarded as interlopers who lacked a commitment to the town's welfare.

See the entry >

Examples:

"... my garden is wildlife friendly, sometimes too friendly. By not being overly concerned about interlopers, it welcomes birds and bugs now, including beneficial insects. They help keep things in balance. Not so welcome are rabbits, but they still find their way in." — David Hobson, The Waterloo (Ontario) Region Record, 16 Apr. 2026

Did you know?

If you keep chickens, a coyote loping around in the vicinity of your coop is not welcome. You'd be justified, both semantically and etymologically, in calling such a coyote an interloper. The -loper part of interloper shares an ancestor with the Old English verb hlēapan, meaning "to leap," and the Dutch verb lopen, meaning "to run." (The verb lope does too.) The prefix inter- means "between" or "among," so an interloper is essentially one that leaps in among others (for example, a flock of hens) without an invitation to do so. Interloper made itself at home among English speakers in the late 1500s; the verb interlope, which arrived close in tow in the early 1600s, is likely a back-formation.

Merriam-Webster's Word of the Day for June 4, 2026 is:

redolent • \RED-uh-lunt\  • adjective

As a synonym of aromatic, the word redolent can describe something that has a noticeable smell without specifying the scent, but more often it is accompanied by of or with and means “full of a specified fragrance,” as in “redolent with incense.” Redolent can also describe something that causes thoughts or memories of something, as in “music redolent of the 1980s.”

// The late-spring meadow was redolent of wildflowers and petrichor.

See the entry >

Examples:

“The store is redolent with the aroma of warm chocolate and an ambience evoking the agricultural roots of cacao with plants and growing tunnels.” — Robert Channick, The Chicago Tribune, 13 Feb. 2026

Did you know?

Redolent traces back to the Latin verb olēre (“to smell”) and is a relative of olfactory, “of, relating to, or connected with the sense of smell.” In its earliest English uses in the 15th century, redolent simply meant “having an aroma.” Today, it usually applies to a place or thing permeated with odors. Scent and memory are famously linked, and an extended use of redolent to mean “evocative” or “suggestive” links them again, as in “lollipops redolent of childhood.”

Merriam-Webster's Word of the Day for June 3, 2026 is:

engender • \in-JEN-der\  • verb

Engender is a formal word that means “to be the source or cause of something.”

// Our monthly book club meetings started as a way to connect and ended up being a great place to engender unity and build life-long friendships.

See the entry >

Examples:

“... ‘During a moment defined by anti-intellectualism, escapism, and AI tools that let you skip cognitive work entirely ... intellectual creators are doing something kinda countercultural,’ says Death To Stock’s culture researcher Agus Panzoni. These influencers, who have already built established communities around intellectual pursuits, hold greater meaning and engender more trust ...” — Markiel Magsalin, Vogue, 15 Apr. 2026

Did you know?

A good paragraph about engender will engender understanding in the reader. Like its synonym generate, engender comes from the Latin verb generare, meaning “to generate” or “to beget,” and when the word was first used in the 14th century, engender meant “propagate” or “procreate.” That literal meaning having to do with creating offspring (which generate shared when it was adopted in the early 16th century) was soon joined by the “to cause to exist or develop, to produce” meaning most familiar to us today. Generare didn’t just engender generate and engender; regenerate, degenerate, and generation have the same Latin root. As you might suspect, the list of engender relatives does not end there. Generare comes from the Latin noun genus, meaning “origin” or “kind.” From this source we took our own word genus, plus gender, general, and generic, among other words.

Merriam-Webster's Word of the Day for June 2, 2026 is:

crux • \KRUKS\  • noun

Crux refers to the most important part of something (such as a problem, issue, or puzzle). It is often used in the phrase "the crux of."

// The crux of the problem is that the project's budget is totally inadequate.

See the entry >

Examples:

"The new trees number in the thousands. ... What will become of this nursery in the wild in the next hundred years, or thousand, is the crux of a scientific and policy dispute. Starkly different visions of how the grove will recover in the long run have implications on how forest managers should act today." — Doug Smith, The Los Angeles Times, 15 Mar. 2026

Did you know?

Latin speakers used crux to refer literally to an instrument of torture, often a cross or stake, and figuratively to the torture and misery inflicted by means of such an instrument. When English speakers adopted crux in the early 18th century, they used it to mean "a puzzling or difficult problem." In the late 19th century, crux developed a more specific use referring to an essential point of a legal case that required resolution before the case as a whole could be resolved. Today, the verdict on crux is that it can be used to refer to any important part of a problem or argument, inside or outside of the courtroom.
