Examples:

"The Torlonia collection, which Alessandro Torlonia moved into a private museum in Rome in 1875, went into hiding in the early 1940s. ... Disputes among family members and with the government left the marbles hidden away, gathering dust and grime. For all those years scholars had to beg and bribe to get in. One government official, desperate to see what gems the Torlonia prince had immured, resorted to dressing up as a cleaner." — Jason Farago, The New York Times, 16 Apr. 2025





Did you know?

Like mural, immure comes from murus, a Latin noun meaning "wall." Immure came to English by way of the Medieval Latin verb immurare, formed from murus and the prefix in- (meaning "in" or "within"). Immure, which first appeared in English in the late 16th century, literally means "to wall in" or "to enclose with a wall," but it has extended meanings as well. In addition to senses meaning "to imprison" and "to entomb," the word sometimes has broader applications, essentially meaning "to shut in" or "to confine." One might remark, for example, that a very studious acquaintance spends most of her time "immured in the library."

Examples:

“Now the book publishing industry has sent a message to all A.I. companies: Our intellectual property isn’t yours for the taking, and you cannot act with impunity. This settlement is an opening gambit in a critical battle that will be waged for years to come.” — Andrea Bartz, The New York Times, 1 Oct. 2025





Did you know?

Don’t let the similarities of sound and general flavor between gambit and gamble trip you up; the two words are unrelated. Gambit first appeared in English in a 1656 chess handbook that was said to feature almost a hundred illustrated gambetts. Gambett traces back first to the Spanish word gambito, and before that to the Italian gambetto, from gamba meaning “leg.” Gambetto referred to the act of tripping someone, as in wrestling, in order to gain an advantage. In chess, gambit (or gambett, as it was once spelled) originally referred to a chess opening whereby the bishop’s pawn is intentionally sacrificed—or tripped—to gain an advantage in position. Gambit is now applied to many other chess openings, but after being pinned down for years, it also finally broke free of chess’s hold and is used generally to refer to any “move,” whether literal or rhetorical, done to get a leg up, so to speak. While such moves can be risky, gambit is not synonymous with gamble, which likely comes from Old English gamen, meaning “amusement, jest, pastime”—source too of game.

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





besotted • \bih-SAH-tud\ • adjective

Someone described as besotted is so in love that they are unable to think clearly; they are utterly infatuated. Besotted can also be used as a synonym of drunk.

// The opening scene of the movie follows a besotted couple at a party, the camera’s focus emphasizing their ignorance of all that’s around them.

Examples:

“Kathrin [tour guide] is endearingly besotted with her adopted country and spoke about it with the reverence of a convert. Some more things I heard from her that contribute to people in Finland being happy included: sauna culture discouraging fatphobia; emphasis on design—that means even very basic, cheap things are beautiful and robust; and, of course, nature.” — Imogen West-Knights, Slate, 27 Aug. 2025

Stumble on the word sot and you will likely find it attached to a person who tends to over-imbibe. The word has referred to a habitual drunkard since the late 16th century, and before that—from the days of Old English—it referred to a fool generally. The now-archaic verb sot followed a similar trajectory, its original meaning of “to cause to appear foolish” being joined later by its “to drink alcohol excessively” meaning. The earliest known recorded use of the related adjective besotted (in the late 16th century, from the the verb besot), however, described a state of figurative intoxication: one besotted was stupefied by love rather than liquor. The still-current sense of besotted meaning “drunk” didn’t show up until the early 19th century. In fact, evidence of the “infatuated” sense of besotted also predates the tipple-related senses of the noun sot, verb sot, and verb besot, suggesting perhaps that love may be the strongest intoxicant of all.

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





mea culpa • \may-uh-KOOL-puh\ • noun

The noun mea culpa is used for a formal acknowledgment of personal fault or error.

// The podcast host's mea culpa did little to satisfy those who found the episode deeply offensive.

Examples:

"... his apology was the best public mea culpa of this century. ... It was delivered without hesitation, qualification or blame shifting." — John Mosig, The Age (Melbourne, Australia), 24 Oct. 2025





Did you know?

Mea culpa means "through my fault" in Latin. Said by itself, it's an exclamation of apology or remorse that is used to mean "It was my fault" or "I apologize." Mea culpa is also a noun, however. A newspaper might issue a mea culpa for printing inaccurate information, or a politician might give a speech making mea culpas for past wrongdoings. Mea culpa is one of many English terms that come from the Latin culpa, meaning "guilt." Some other examples are culpable ("meriting condemnation or blame especially as wrong or harmful"), culprit ("one guilty of a crime or a fault"), and exculpate ("to clear from alleged fault or guilt").

Did you know?

In Homer’s Iliad, Hector, the eldest son of King Priam of Troy, was a model soldier, son, father, and friend, the champion of the Trojan army until he was killed by the Greek hero Achilles. So how did his name become a verb meaning “to intimidate or harass”? That use was likely influenced by gangs of rowdy street toughs who roamed London in the 17th century and called themselves “Hectors.” They may have thought themselves gallant young blades (that’s sense 3b(3)), but to the general populace they were swaggering bullies who intimidated passersby and vandalized property.
