Merriam-Webster's Word of the Day for August 29, 2026 is:

kith • \KITH\  • noun

Kith is an old-fashioned term that refers to familiar friends, neighbors, or relatives. It is often used in the phrase “kith and kin,” which means “friends and relatives.”

// Spending time with kith and kin at the end of the summer is the highlight of our year.

Examples:

“One thing that you could usually count on was the loyalty of your kith and kin, your friends and family. But now it seems that the closeness of family and relatives is more difficult to maintain in the modern world.” — James Morabito, The Buffalo (New York) News, 26 July 2026

Did you know?

If you’d used the word kith a thousand years ago, you might have been referring to knowledge, or to a homeland, or to your neighbors and acquaintances. While those first two meanings of kith have long since fallen out of use, the word endures with a meaning very close to that “neighbors and acquaintances” one. Today kith appears almost exclusively in the phrase kith and kin, meaning “friends and relatives.” (Kin, another ancient word, can also refer independently to relatives.) Occasionally you will see kith and kin used to refer only to family members, much to the chagrin of those who despise redundancy in language. If you wish to avoid redundancy charges you’ll be sure to include friends as well as family among your “kith and kin.”

Merriam-Webster's Word of the Day for August 28, 2026 is:

cogent • \KOH-junt\  • adjective

Cogent is a formal word that describes something that is very clear and easy for the mind to accept and believe. It is used as a synonym of convincing.

// At the town meeting, citizens presented many cogent arguments in support of building a new senior center.

See the entry >

Examples:

“The history of art reads here as one long, free verse poem-in-progress, gorgeous and absorbing. Even so, many of the most memorable moments come in the form of cogent micro-essays, smartly curated ensembles of work bearing a legible, lucid premise.” — Leah Ollman, The Los Angeles Times, 24 Apr. 2026

Did you know?

A cogent argument is one that really drives its point home because it is clear, coherent, and readily understandable, and perhaps also because of the etymological history of cogent. Cogent comes from the Latin verb cōgere, meaning “to drive or force together.” Something described as cogent fuses thoughts and ideas into a meaningful whole that others can readily grasp and accept. A cogent explanation is a convincing one, and cogent analysis has us nodding along because it is clear and pertinent. Cōgere was formed in Latin by combining the prefix co- with the verb agere, “to drive, lead, or act,” a root which is also the source of our familiar noun agent. Handily enough, one definition of agent is “a means or instrument by which a guiding intelligence achieves a result.” It follows logically then that cogency is often a worthwhile agent, indeed.

Merriam-Webster's Word of the Day for August 27, 2026 is:

southpaw • \SOUTH-paw\  • noun

Southpaw is an informal word for someone who is left-handed. It is especially used for a left-handed baseball pitcher or boxer.

// The team’s new pitcher is a southpaw with a wicked knuckleball.

See the entry >

Examples:

“The Sox southpaw’s perfect game bid ended when the Yankees loaded the bases with two outs in the fourth …” — Gabrielle Starr, The Boston Herald, 7 June 2026

Did you know?

Sandy Koufax, Lefty Grove, Whitey Ford—there’s no doubt these southpaws are some of the greatest baseball players of all time. What is in doubt is the origin of the word southpaw. One popular theory ties it to the layout of baseball parks. To keep the afternoon sun out of batters’ eyes, diamonds were supposedly built so that the pitcher faced west, with their left arm, therefore, pointed south. This theory strikes out however, on account of the earliest known uses of the compound south paw referring simply to one’s left hand, unrelated to baseball. It wasn’t until later in the century that the word began to be used, via metonymy, first for a left-handed person, and then specifically for a left-handed pitcher.

Merriam-Webster's Word of the Day for August 26, 2026 is:

devolve • \dih-VAHLV\  • verb

To devolve is to gradually go from an advanced state to a less advanced state, or to pass something, such as responsibility or power, from one person or group to another at a lower level of authority.

// Somehow the debate devolved into a petty competition to see who could get more applause.

// Community leaders hope that the new government will devolve more power to the community itself.

Examples:

“He accused board members of personally profiting from the parking and landscaping policies. Board meetings soon devolved into a cacophony of charges, countercharges and shouting.” — Elizabeth Williamson, The New York Times, 19 Nov. 2025

Did you know?

Evolve? Check. Revolve? Check. Devolve? Now we’re on a roll—literally. All three of these words (and more) evolved from the Latin verb volvere, meaning “to set in a circular course, to cause to roll, to bring round.” The Latin ēvolvere means “to roll out or away”; revolvere means “to roll back to a starting point”; and dēvolvere means “to roll (something) down.” In its earliest uses in the 15th century, devolve literally meant “to roll onward or downward.” Today the word is typically used for a more figurative rolling down, as when an organization devolves power—that is, passes power down—to those at a lower level of authority, or when a deteriorating situation is described as “devolving into chaos.” One word, multiple uses. That’s just how English rolls.

Merriam-Webster's Word of the Day for August 25, 2026 is:

tilde • \TIL-duh\  • noun

Tilde refers to the mark ~ placed especially over the letter n (as in the Spanish señor, meaning "sir") to denote the sound \nʸ\, or over vowels (as in the Portuguese irmã, meaning "sister") to indicate nasality. When a tilde appears as an independent character, it usually means "approximately" (as in "we'll be there in ~ 30 minutes").

// A familiar example of the tilde appears in the name of the Brazilian city São Paulo.

See the entry >

Examples:

"Californians with accents, tildes and other diacritical marks in their names will soon be able to have their vital records accurately reflect their names." — Linh Tat, Orange County (California) Register, 30 Dec. 2025

Did you know?

The terms piña colada and La Niña share more than just a "cool" factor: both are Spanish loan words whose spellings include tildes, those wavy marks which in these examples are placed over the letter n to indicate a blend of the sounds of n and y. Tilde is itself a Spanish borrowing rooted in the Latin titulus, an ancestor of the English words title and titular that means "title" or "inscription." The Spanish and English applications of tilde are distinct. In Spanish, tilde refers most commonly to the accent symbol, while ñ is its own member of the alphabet (pronounced "EN-yay"). In contrast, English speakers use tilde specifically for the aforementioned mark. In addition to functioning as a diacritic—that is, a mark paired with a character to indicate pronunciation—the tilde may be used as an independent character to indicate approximation, negation in logic, or similarity in mathematics.

Merriam-Webster's Word of the Day for August 24, 2026 is:

expeditious • \ek-spuh-DISH-us\  • adjective

Expeditious is a formal word that is used to describe someone acting in a quick and efficient way, or something done in such a manner.

// Both sides hoped for an expeditious resolution of the dispute.

See the entry >

Examples:

“Inspectors were on campus Friday afternoon with a certified arborist to determine which trees are protected and the extent to which any damage or removals have occurred, according to the city. ‘The City is prepared to conduct this inspection work in an expeditious manner and supports the goal of returning students to a safe campus as soon as possible,’ the city’s statement said.” — Ryan Carter, The Los Angeles Daily News, 10 July 2026

Did you know?

Expeditious has had quite the journey through the English language. It comes to us from the related noun expedition, which in turn comes from the Latin verb expedire (“to set free” or “to make ready”). When expedition first set forth in English in the 1400s, it did so with two meanings that are still in use today, “a journey especially by a group of people for a specific purpose” and “efficient promptness.” Expeditious followed as an adjectival form of the latter. Something (such as, say, preparation for a long voyage) done expeditiously is done quickly and efficiently; in other words, it is expedited. Like expeditious and expedition, expedite too comes from expedire.

Merriam-Webster's Word of the Day for August 23, 2026 is:

prowess • \PROW-us\  • noun

Prowess refers to someone’s great ability, skill, or talent for something specified, as in “the pop star's vocal prowess” or “a lawyer of great prowess.”

// Already a proven virtuoso on guitar, she extends her considerable instrumental prowess to the piano throughout her new album as well.

See the entry >

Examples:

“On another Friday ... I led a nature writing workshop at the library’s Fowler branch. ... I had everyone draw a map of a place they loved and populate their maps with landmarks. Then we all went around and shared our drawings. Inevitably (after first acknowledging our lack of artistic prowess) stories emerged. Walks with long-gone, beloved dogs. Times someone had been caught out in bad weather.” — Steve Edwards, Literary Hub, 4 Dec. 2025

Did you know?

Prowess is a word with a lot to be proud of. Not only has it performed gallantly for the English language since the 13th century, but it has stayed relatively stalwart in hewing to its original meaning, which is quite an accomplishment. When prowess first joined the ranks of the lexicon, it could be used to refer to bravery, skill, and valor—especially those virtues as encountered in military contexts—or to individual acts of derring-do. The latter was usually used in the plural, as when people waxed rhapsodic about the “prowesses” of knights or some such. Today’s “extraordinary ability” meaning, which developed in the 17th century, tends to stick to the singular form, as when it’s used to describe those with intellectual prowess, or to someone known for their prowess as a fundraiser. 

Merriam-Webster's Word of the Day for August 22, 2026 is:

august • \aw-GUST\  • adjective

The word august, which is pronounced with the accent on "gust," describes someone or something marked by majestic dignity or grandeur.

// We toured the old mansion's august halls and expansive grounds.

Examples:

"His tone is temperate, but the words echo through the State Capitol’s Assembly chamber, the august backdrop for his speech." — Maya Singer, Vogue, 1 Feb. 2026

Did you know?

The Roman republican calendar spanned just ten months, from March (then Martius) through December. The last five months were each named for their numerical place on the calendar: Quintilis (fifth), Sextilis (sixth), September (seventh), October (eighth), November (ninth), and December (tenth). January and February were eventually added to create a twelve-month year, obscuring the relationship between these months and their titles. So it was a welcome change when the Roman Senate honored Gaius Octavius (aka Octavian), the first Roman emperor, by changing Sextilis to Augustus—the designation taken by Octavian from the Latin adjective augustus meaning "worthy of honor" or "venerable." Although August has been the English name of the eighth month of the year since before the 12th century, it wasn't until the late 1500s that august came to be used as an adjective (pronounced \aw-GUST\), more or less as augustus was in Latin.

Merriam-Webster's Word of the Day for August 21, 2026 is:

rigmarole • \RIG-uh-muh-rol\  • noun

Rigmarole refers to a long, complicated, and annoying process, description, etc.

// We went through the rigmarole of installing, registering, and activating the software before we found out it wouldn’t work.

See the entry >

Examples:

“Over the last 10 years or so, I’ve had an on-again, off-again relationship with running. On the one hand, I love it for the mental benefits. My mind always feels clearer after a run and it can be an escape from the rigmarole of life. But on the other hand, it seems that every few years, some mild injury befalls me that slows my momentum, or I move to a new city and lose the routine of running at a time and place.” — Maura Fox, The San Diego Union-Tribune, 6 Sept. 2025

Did you know?

In the Middle Ages, the term Rageman or Ragman referred to a game in which a player randomly selected a string attached to a roll of verses and read the selected verse. The roll was called a Ragman roll after a fictional king purported to be the author of the verses. By the 16th century, ragman and ragman roll were being used figuratively to mean “a list or catalog.” Both terms fell out of written use, but ragman roll persisted in speech, and in the 18th century it resurfaced in writing as rigmarole, with the meaning “a succession of confused, meaningless, or foolish statements.” In the mid-19th century rigmarole (also spelled rigamarole, reflecting its common pronunciation) acquired the sense referring to a complex and tedious procedure.

Merriam-Webster's Word of the Day for August 20, 2026 is:

divulge • \dih-VULJ\  • verb

To divulge something, especially secret or private information, is to make it known.

// Rather than divulge the baby name we’ve chosen, we’re waiting till the little one arrives to make introductions.

See the entry >

Examples:

“Sun Ra’s agent had called, he said. ... The Arkestra was heading out on tour soon, to Europe, and Sonny wanted the three of us to join him. ... After we’d calmed down, Don divulged the hitch: the tour would take us away for the school year’s last weeks, meaning we would miss exams and also all the end-of-college parties.” — Michael Lowenthal, Place Envy: Essays in Search of Orientation, 2026

Did you know?

Information divulged is typically secret, or known only to insiders, and it isn’t usually shouted from the rooftops. But when divulge first entered English in the 15th century, it did so as a synonym of proclaim: divulging involved declaring or announcing something to the public, a duty of town criers from Lizard Point to Dunnet Head. The word’s source is the Latin verb vulgare, “to make known,” which traces ultimately back to the Latin noun vulgus, meaning “common people” or “mob.” While nowadays divulge can presumably involve blabbing to the rabble, the word usually implies a more careful and considered approach to sharing sensitive information.
