deliquesce
Merriam-Webster's Word of the Day for October 29, 2025 is: deliquesce • \del-ih-KWESS\ • verb Deliquesce can mean "to dissolve or melt away" or, in reference to some fungal structures (such as mushroom gills), "to become soft or liquid with age or maturity." // The mushrooms deliquesced into an inky fluid. See the entry > Examples: "He would mould his figures in full in wax, then take a hot knife and—like a metaphysical surgeon—cut away triangles, rhomboids, flaps and scraps, until only a latticework was left. These new shapeshifting figures comprised more gaps than joins: bodies in the delicate, arduous process of shedding their skins, scattering into metal petals, being eroded and deliquesced. Things were freshly able to pass through these painstakingly hard-to-cast bronzes: light, air, sight." — Robert Macfarlane, Apollo, 1 May 2025 Did you know? Deliquesce comes from the prefix de- ("from, down, away") and a form of the Latin verb liquēre, meaning "to be fluid." Things that deliquesce, it could be said, turn to mush in more ways than one. In scientific contexts, a substance that deliquesces absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution. When plants and fungi deliquesce, they lose rigidity as they age. When deliquesce is used in non-scientific contexts, it is often in a figurative or humorous way to suggest the act of "melting away" under exhaustion, heat, or idleness, as in "teenagers deliquescing in 90-degree temperatures."

menagerie
Merriam-Webster's Word of the Day for October 28, 2025 is: menagerie • \muh-NAJ-uh-ree\ • noun Menagerie refers to a collection of animals kept especially to be shown to the public, as well as a place where such animals are kept. It can also refer figuratively to any varied mixture of things. // The aviary featured a menagerie of exotic birds. // The space is eclectically furnished with a menagerie of flea market finds. See the entry > Examples: “The creatures are usually found hanging from phones or handbags ... or clutched as a kind of pet. They come in a menagerie of more than three hundred collectible forms. They can be matched to a personal style or mood: pink fur for when you’re feeling flirty; glowing red eyes for a bit of an edge ...” — Kyle Chayka, The New Yorker, 20 Aug. 2025 Did you know? Back in the days of Middle French, ménagerie meant “the management of a household or farm” or “a place where animals are tended.” When English speakers adopted menagerie in the 1600s, they applied it specifically to places where wild and often also foreign animals were kept and trained for exhibition, as well as to the animals so kept. This second meaning was eventually generalized to refer to any varied mixture, especially one that includes things that are strange or foreign to one’s experience.

acerbic
Merriam-Webster's Word of the Day for October 27, 2025 is: acerbic • \uh-SER-bik\ • adjective Something described as acerbic is sharply or bitingly critical, sarcastic, or ironic in temper, mood, or tone. // The comedian draws crowds that appreciate his acerbic wit. See the entry > Examples: "Whether she's giving a sarcastic eye-roll, tossing off an acerbic zinger, or seducing with a come-hither stare, [actress Jennifer] Simard intimately understands the art of underplaying." — Christopher Wallenberg, The Boston Globe, 1 June 2025 Did you know? English speakers created acerbic in the 19th century by combining the adjective acerb with the suffix -ic-. Acerb had already been around for a couple centuries, but for most of that time it had been used only to describe foods with a sour taste. (Acerb is still around today, but now it's simply a less common synonym of acerbic.) Acerbic and acerb ultimately come from the Latin adjective acerbus, which can mean "harsh" or "unpleasant." Another English word that comes from acerbus is exacerbate, which means "to make more violent or severe."

cognoscente
Merriam-Webster's Word of the Day for October 26, 2025 is: cognoscente • \kahn-yuh-SHEN-tee\ • noun Cognoscente refers to a person with expert knowledge in a subject. It is usually encountered in its plural form, cognoscenti, and preceded by the. // The audience at the club, though small, was full of writers, musicians, and other noteworthy members of the jazz cognoscenti. See the entry > Examples: "Even as [Ray] Bradbury was embraced by the New York cognoscenti—traveling to the city in the fall of '46, drawing the attention of Truman Capote, meeting Gore Vidal, dancing with Carson McCullers at a Manhattan party—Mars beckoned. Yet he would not dare tell his New York associates, for fear of being laughed out of the room." — Sam Weller, LitHub.com, 28 Apr. 2025 Did you know? Cognoscente and connoisseur—both terms for those in the know—are more than synonyms; they’re also linguistic cousins. Both terms descend from the Latin verb cognōscere, meaning "to know," and they’re not alone. You might guess that cognizance and cognition are members of the cognōscere clan. Do you also recognize a family resemblance in recognize? Can you see through the disguise of incognito? Did you have a premonition that we would mention precognition? Cognoscente itself came to English by way of Italian and has been a part of the language since the late 1700s.

wreak
Merriam-Webster's Word of the Day for October 25, 2025 is: wreak • \REEK\ • verb Wreak means “to cause something very harmful or damaging.” It is often used with on or upon. // The virus wreaked havoc on my laptop. See the entry > Examples: “Ours is a geography of cataclysm: Santa Anas wreak their psychic wrath; the odor of disaster seeps from the street like that sulfurous egg smell of the La Brea Tar Pits.” — John Lopez, The Hollywood Reporter, 6 Sept. 2025 Did you know? In its early days, wreak was synonymous with avenge, a meaning exemplified when Shakespeare’s Titus Andronicus proclaims “We will solicit heaven, and move the gods / To send down Justice for to wreak our wrongs.” This sense is now archaic, but the association hasn't been lost: although wreak is today most often paired with havoc, it is also still sometimes paired with words like vengeance and destruction. We humbly suggest you avoid wreaking any of that, however, no matter how badly you may crave your just deserts.
