Merriam-Webster's Word of the Day for June 13, 2025 is: rambunctious \ram-BUNK-shuss\ adjective Rambunctious describes someone or something showing uncontrolled exuberance. // On my first day of student teaching, I was tasked with managing a class of rambunctious youngsters. [See the entry >](https://www.merriam-webster.com/dictionary/rambunctious) Examples: "To juvenile loggerhead sea turtles, a tasty squid might as well be a disco ball. When they sense food—or even think some might be nearby—these reptiles break into an excited dance. ... Researchers recently used this distinctive behavior to test whether loggerheads could identify the specific magnetic field signatures of places where they had eaten in the past. The results, published in Nature, reveal that these rambunctious reptiles dance when they encounter magnetic conditions they associate with food." — Jack Tamisiea, Scientific American, 12 Feb. 2025 Did you know? Rambunctious first appeared in print in the early half of the 19th century, at a time when the fast-growing United States was forging its identity and indulging in a fashion for colorful new coinages suggestive of the young nation's optimism and exuberance. [Rip-roaring](http://www.merriam-webster.com/dictionary/rip-roaring), [scalawag](http://www.merriam-webster.com/dictionary/scalawag), [scrumptious](http://www.merriam-webster.com/dictionary/scrumptious), [hornswoggle](http://www.merriam-webster.com/dictionary/hornswoggle), and [skedaddle](http://www.merriam-webster.com/dictionary/skedaddle) are other examples of the lively language of that era. Did Americans alter the largely British [rumbustious](https://www.merriam-webster.com/dictionary/rumbustious) because it sounded, well, British? That could be. Rumbustious, which first appeared in Britain in the late 1700s just after the signing of the Declaration of Independence, was probably based on [robustious](https://www.merriam-webster.com/dictionary/robustious), a much older adjective meaning both "robust" and "boisterous."

Merriam-Webster's Word of the Day for June 12, 2025 is: impute \im-PYOOT\ verb To impute something, such as a motive, act, or emotion, to a person or thing is to assert that the person or thing is guilty of that motive, act, emotion, etc. // It is shocking that they would impute such awful motives to me. [See the entry >](https://www.merriam-webster.com/dictionary/impute) Examples: “California is about to ease into the 2026 race for governor, and if you can pick any of the current candidates from a police lineup, either you work in Sacramento, have an unhealthy obsession with state politics, or both. That’s not to impute criminality on the part of any of those running to succeed the term-limited Gavin Newsom. ... Rather, those bidding to become California’s 41st governor aren’t exactly a collection of name-in-lights celebrities.” — Mark Z. Barabak, The Los Angeles Times, 9 Jan. 2025 Did you know? Impute is a formal word typically used in contexts in which a motive, act, or emotion is credited or ascribed to someone, especially falsely or unfairly. For example, if you impute dishonesty to someone you’re asserting that they’re not telling the truth. And if you impute selfish motives to someone’s actions you’re asserting that they were motivated by selfishness. In the form imputed the word is often paired with income: [imputed income](https://bit.ly/3HltYN9) is income calculated from the supposed value of intangible or non-cash sources, such as use of a company car, or an employee discount. What’s the connection between these meanings? Both involve considering someone or something in a particular way, tying each meaning to the word’s Latin ancestor: putare means “to consider.”

Merriam-Webster's Word of the Day for June 11, 2025 is: debilitating \dih-BILL-uh-tay-ting\ adjective Debilitating is a formal word used to describe things that seriously impair strength or the ability to function. // She suffers from debilitating migraines. // The class helped him conquer his debilitating fear of public speaking. [See the entry >](https://www.merriam-webster.com/dictionary/debilitating) Examples: "Worry is such a debilitating thing that robs you of your energy ..." — Georgia Nicols, The Denver Post, 3 Apr. 2025 Did you know? Debilitating describes things that cause serious impairment of strength or ability to function. The word appears in both medical and general contexts; someone can suffer from debilitating nausea or debilitating stage fright. An adjective that takes the form of a verb, debilitating dates to the mid-17th century, making it the youngest of a trio: its source, the verb [debilitate](https://www.merriam-webster.com/dictionary/debilitate) ("to impair the strength of"), dates to the early 16th century, and the noun [debility](https://www.merriam-webster.com/dictionary/debility) ("weakness, infirmity") has been in use since the 15th century. All come from the Latin word for "weak," debilis. Polyglots may recognize the influence of debilis in words from Spanish, Russian, Czech, Turkish, Danish, and many other languages as well.

Merriam-Webster's Word of the Day for June 10, 2025 is: minutia \muh-NOO-shee-uh\ noun Minutia refers to a small or minor detail. It is usually used in its plural form minutiae. // Unaccustomed to [legalese](https://www.merriam-webster.com/dictionary/legalese), I was bewildered by the contract's minutiae. [See the entry >](https://www.merriam-webster.com/dictionary/minutia) Examples: “The novel is an intricate thatch of corkscrew twists, vivid characters, dead-on colloquial dialogue, and lawyerly minutiae that culminates in a courtroom showdown worthy of Dominick Dunne.” — David Friend, Vanity Fair, 1 Apr. 2025 Did you know? We’ll try not to bore you with the minor details of minutia, though some things are worth noting about the word’s history and usage. It’ll only take a minute! Minutia was borrowed into English in the 18th century from the Latin plural noun minutiae, meaning “trifles” or “details,” which comes from the singular noun minutia, meaning “smallness.” In English, minutia is most often used in the plural as either minutiae (pronounced \muh-NOO-shee-ee\\) or, on occasion, as simply minutia. The Latin minutia, incidentally, comes from minutus (also the ancestor of the familiar English word [minute](https://www.merriam-webster.com/dictionary/minute)), an adjective meaning “small” that was created from the verb minuere, meaning “to lessen.”

Merriam-Webster's Word of the Day for June 9, 2025 is: eloquent \EL-uh-kwunt\ adjective An eloquent speaker or writer expresses ideas forcefully and fluently; an eloquent speech or piece of writing likewise expresses ideas in such a way. Eloquent can also describe something that is vividly or movingly expressive. // She received high marks for her eloquent essay about gardening with her grandmother. // Their success serves as an eloquent reminder of the value of hard work. [See the entry >](https://www.merriam-webster.com/dictionary/eloquent) Examples: "Her [author Michelle Cusolito's] concise yet eloquent text immerses young people in the watery setting, letting them feel the whales' clicks as they 'tingle' and 'vibrate' and emphasizing the strength of these animals' social bonds." — Kirkus Reviews, 1 May 2025 Did you know? Words are powerful, especially when strung together in just the right sequence. A well-crafted sentence (or one who crafts it) might be described as eloquent, a word that comes from the Latin verb loquī, meaning "to talk or speak." (The adjective [loquacious](https://www.merriam-webster.com/dictionary/loquacious) is another loquī descendent; it describes a person who is skilled at or has an affinity for talking.) Words are not alone in conveying emotion, and eloquent is also used to describe what we find vividly or movingly expressive, as when novelist and poet [Thomas Hardy](https://www.britannica.com/biography/Thomas-Hardy) wrote of "a burst of applause, and a deep silence which was even more eloquent than the applause."

Merriam-Webster's Word of the Day for June 8, 2025 is: cataract \KAT-uh-rakt\ noun Cataract refers to a clouding of the lens of the eye, or of its surrounding transparent membrane, that obstructs the passage of light. Cataract is also used, often in literature, to refer to a waterfall, steep rapids in a river, or to a downpour or flood. // Cataracts are common but can be corrected with surgery. // The roaring cataract is one of the park’s most majestic sights. [See the entry >](https://www.merriam-webster.com/dictionary/cataract) Examples: “I became a grandmother at the beginning of the decade and again at the end. I decided what kind of grandmother I wanted to be. I came to accept my identity as a writer. I retired from teaching after twenty years. I continue to work as a social work consultant. I had cataract surgery and can see better than I have in years.” — Lyn Slater, How to Be Old: Lessons in Living Boldly from the Accidental Icon, 2024 Did you know? The ocular meaning of cataract that English users are most familiar with is also the oldest. It dates to the 14th century and comes from the Latin word cataracta, meaning “[portcullis](https://www.merriam-webster.com/dictionary/portcullis),” probably because a cataract in one’s eye obstructs vision much like a portcullis’s heavy iron grating obstructs passage into a fortress or castle. Cataracta has another meaning, however—“waterfall”—and that meaning gave English the water-related meanings that came in later centuries. The connection between the two Latin meanings can be seen in katarassein, the Greek source of cataracta. It means “to dash down,” describing the action of both the slamming portcullis and the cascading waterfall.

Merriam-Webster's Word of the Day for June 7, 2025 is: abstruse \ub-STROOSS\ adjective Abstruse is a formal word used to describe something that is hard to understand. // I avoided taking this class in past semesters because the subject matter is so abstruse, but the professor does a good job explaining the concepts as clearly as possible. [See the entry >](https://www.merriam-webster.com/dictionary/abstruse) Examples: “The EP’s lyrics are suitably abstruse. The title ‘Marry Me Maia’ sounds forthright in its intentions, but the song instead offers cryptic references and obfuscation. The result is like peeping in on a private conversation: fascinating and impassioned but fundamentally obscure.” — Ben Cardew, Pitchfork, 31 Mar. 2025 Did you know? Look closely at the following Latin verbs, all of which come from the verb trūdere (“to push, thrust”): [extrudere](https://www.merriam-webster.com/dictionary/extrude), [intrudere](https://www.merriam-webster.com/dictionary/intrude), [obtrudere](https://www.merriam-webster.com/dictionary/obtrude), [protrudere](https://www.merriam-webster.com/dictionary/protrude). Remove the last two letters of each of these and you get an English descendant whose meaning involves pushing or thrusting. Another trūdere offspring, abstrūdere, meaning “to conceal,” gave English abstrude, meaning “to thrust away,” but that 17th-century borrowing has fallen out of use. An abstrūdere descendant that has survived is abstruse, an adjective that recalls the meaning of its Latin parent abstrūsus, meaning “concealed.” Like the similar-sounding [obtuse](https://www.merriam-webster.com/dictionary/obtuse), abstruse describes something difficult to understand—that is, something that has a “concealed” meaning.

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. [See the entry >](https://www.merriam-webster.com/dictionary/festoon#h2) 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](https://www.merriam-webster.com/dictionary/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. [See the entry >](https://bit.ly/3RlxQzM) 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](https://www.merriam-webster.com/dictionary/fake), [false](https://www.merriam-webster.com/dictionary/false), and [counterfeit](https://www.merriam-webster.com/dictionary/counterfeit). // We were disappointed to find out that the purses we bought were bogus. // The company was investigated over several bogus claims that their products could guarantee better health for their customers. [See the entry >](https://www.merriam-webster.com/dictionary/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](https://www.merriam-webster.com/dictionary/argot) of [wildcat banks](https://www.britannica.com/money/wildcat-bank) (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](https://www.merriam-webster.com/dictionary/sham)) to the fairly new ([fugazi](https://www.merriam-webster.com/slang/fugazi)).
