effulgence

Merriam-Webster's Word of the Day for July 10, 2026 is: effulgence • \ih-FULL-junss\  • noun Effulgence means “radiant splendor” or “brilliance.” // Guests oohed and aahed at the sudden effulgence of the pagoda, as the last of its hundreds of candles were finally lit. See the entry > [https://www.merriam-webster.com/dictionary/effulgence] Examples: “No one knows who suggested that the building be lit at night. But the obvious inspiration was Times Square, an area famous for its nighttime effulgence.” — Robert Sharoff, FastCompany.com, 7 July 2025 Did you know? Need a shiny word to bust out at your next disco party, planetarium visit, or fireworks gathering? How about effulgence? It’s not a shiny “new” word, having made its English language debut in the 17th century, but it’s unusual and has a lovely Latin pedigree: the verb fulgēre, meaning “to shine.” Effulgence isn’t used for bog-standard [https://www.merriam-webster.com/dictionary/bog-standard] brightness, however; it’s reserved for shininess that dazzles, inspires, leaves you gobsmacked—in other words, “radiant splendor.”

tacit

Merriam-Webster's Word of the Day for July 9, 2026 is: tacit • \TASS-it\  • adjective Tacit is a formal adjective used to describe something that is expressed or understood without being directly stated. // As roommates, we had a tacit agreement that we would never pry into each other’s affairs. See the entry > [https://www.merriam-webster.com/dictionary/tacit] Examples: “Where modern documentaries are slick productions filled with preconceived notions, embedded narratives, and tacit approval of their subjects, [Frederick] Wiseman’s work is slow, contemplative, and refreshingly slant-free.” — Kevin Slane, Boston.com, 24 Feb. 2026 Did you know? In the first chapter of Emily Brontë’s Wuthering Heights [https://www.britannica.com/topic/Wuthering-Heights], the narrator Mr. Lockwood recounts warily encountering three dogs. Although he was sure to sit still, he admits that “imagining they would scarcely understand tacit insults, I unfortunately indulged in winking and making faces at the trio” (one subsequently leapt onto his knees in fury). His tacit insults were, by the relevant definition of tacit, not expressed with words (instead he used facial expressions). Tacit can also mean “implied or indicated (as by an act or by silence) but not expressed,” as when a tacit agreement is understood without being directly stated, and tacit approval is silently granted. Tacit traces back to the Latin verb tacēre, meaning “to be silent,” which is also the ancestor of the English adjective taciturn [https://www.merriam-webster.com/dictionary/taciturn], used to describe someone who tends to be quiet.

gambol

Merriam-Webster's Word of the Day for July 8, 2026 is: gambol • \GAM-bul\  • verb Gambol means "to run or jump in a lively way." It is used as a synonym of frolic [https://www.merriam-webster.com/dictionary/frolic]. // There are few sights more charming than that of lambs gamboling about in a meadow in full flower. See the entry > [https://www.merriam-webster.com/dictionary/gambol] Examples: "There's also charming footage of a couple gamboling in Central Park that might be some of the first scenes Warhol ever shot ... They're so lighthearted and playful, they're more in the spirit of his jaunty commercial drawings from the 1950s than of the deadpan Pop Art he was just then perfecting." — Blake Gopnik, The New York Times, 30 Jan. 2026 Did you know? In Middle French, the noun gambade referred to the frisky spring of a jumping horse. In the early 1500s, its influence leapt into English twice, lending a playful bounce to both noun and verb forms of gambol. (The noun means "a skipping or leaping about in play.") Neither English word is restricted to horses, but rather can be used of any frolicsome creature. The more common of the two, the verb, suggests levity and spontaneity, and it tends to be used especially of the lively activity of children or animals engaged in active play.

perfunctory

Merriam-Webster's Word of the Day for July 7, 2026 is: perfunctory • \per-FUNK-tuh-ree\  • adjective Perfunctory is a formal word used to describe something that is done without energy or enthusiasm because of habit or because it is expected. // By the time my favorite band got to the last stop of the tour, their performance felt perfunctory. See the entry > [https://www.merriam-webster.com/dictionary/perfunctory] Examples: “Even a perfunctory ending can’t take away from the film’s fiery commitment to bearing witness to misogyny’s bitter fruit. Harris’ vision as a first-time filmmaker is crystal clear, and Is God Is already feels timeless, like a parable that could have been written decades ago, and will be handily passed down as pointed social critique for decades to come.” — Aisha Harris, NPR, 15 May 2026 Did you know? A perfunctory explanation of the origins of perfunctory would be this: it comes from Latin. But given our passion for language, we can’t resist giving you all the details. Borrowed in the late 16th century, the word is specifically from the Late Latin perfunctorius, meaning “done in a careless or superficial manner.” Perfunctorius traces back to a form of perfungi (“to accomplish, perform, get through with”) and ultimately comes from two Latin sources, per-, meaning “through,” and fungi, meaning “to perform.” Fungi is also a source of such words as function [https://www.merriam-webster.com/dictionary/function], defunct [https://www.merriam-webster.com/dictionary/defunct], and fungible [https://www.merriam-webster.com/dictionary/fungible], but not fungus [https://www.merriam-webster.com/dictionary/fungus]; that word is also from Latin, but it is most likely a modification of the Greek word spongos, meaning “sponge [https://www.merriam-webster.com/dictionary/sponge].”

deepfake

Merriam-Webster's Word of the Day for July 6, 2026 is: deepfake • \DEEP-fayk\  • noun Deepfake refers to an image or recording that has been convincingly altered and manipulated to misrepresent someone as doing or saying something that was not actually done or said. // The leaked video incriminating the school's dean was discovered to be a deepfake. See the entry > [https://www.merriam-webster.com/dictionary/deepfake] Examples: "Overall, the deepfakes are impressive, if not maybe a tad uncanny, showing a near-perfect replica of how Jagger, Keith Richards and Ronnie Wood looked in the late '70s." — Ethan Millman, The Hollywood Reporter, 14 May 2026 Did you know? The old maxim "things aren’t always as they seem" seems more true than ever in the age of deepfakes. A deepfake is an image, or a video or audio recording, that has been edited using an algorithm to replace the person in the original with someone else (especially a public figure) in a way that makes it look authentic. The fake in deepfake is transparent: deepfakes are not real. The deep is less self-explanatory: this half of the term is specifically influenced by deep learning [https://www.merriam-webster.com/dictionary/deep-learning]—that is, machine learning using artificial neural [https://www.merriam-webster.com/dictionary/neural] networks with multiple layers of algorithms [https://www.merriam-webster.com/dictionary/algorithm].
