Examples:

"Once upon a time, music critics were known for being crankier than the average listener. [Taylor] Swift once castigated a writer who'd had the temerity to castigate her, singing, 'Why you gotta be so mean?'" — Kelefa Sanneh, The New Yorker, 25 Aug. 2025

When you're feeling saucy, there's no shortage of words in the English language you can use to describe the particular flavor of your metaphorical sauce, from audacity and effrontery to the Yiddish-derived fan favorite chutzpah. If we may be so bold, let us also suggest temerity: it comes from the Latin temere, meaning "recklessly" or "haphazardly," and is good for suggesting boldness even in the face of danger or likely punishment. Temerity is a formal word, rarely used in casual writing or conversation, but provided you have the cheek to flout this convention, you may be thinking "what have I got to lose?"

Merriam-Webster's Word of the Day for November 9, 2025 is:

improvident • \im-PRAH-vuh-dunt\  • adjective

Improvident is a formal word used to describe something that does not foresee or provide for the future, especially with regard to money. An improvident relationship, habit, or practice is financially unwise or impractical.

// The directors were blasted at the committee hearing for their improvident use of public money.

See the entry >

Examples:

“The problem is worst in affluent countries like the U.S., where more than two hundred pounds of food per person get thrown away each year. ‘Even modest food waste reductions would translate into considerable cumulative savings,' Smil observes. Then, there's the waste that results from improvident eating habits. If photosynthesis has a low conversion rate, feeding crops to animals compounds the problem many times over.” — Elizabeth Kolbert, The New Yorker, 23 June 2025

Did you know?

Improvident describes someone's actions or habits as being unwise with regard to saving or providing for the future. It's a formal word, but the behavior it describes is well illustrated by many of the stories people hear or read as children, including some of the world's oldest. In Aesop's fable “The Ant and the Grasshopper,” the grasshopper could certainly be called improvident—he spends all summer singing and dancing while the ant works hard to prepare for winter by storing food, and at the end of the short tale is cold and starving. While today improvident is used mostly in the context of money, and those who are irresponsible with it, one can be improvident with other things (such as time or food), even happily. In another children's tale, The Tale of the Flopsy Bunnies, author Beatrix Potter introduces the titular family of bunnies, sleepy from eating too much lettuce, as follows: “they were very improvident and cheerful.”

Merriam-Webster's Word of the Day for November 8, 2025 is:

bromide • \BROH-myde\  • noun

A bromide is a statement intended to make someone feel happier or calmer, but too dull and unoriginal to be effective.

// Their speech had nothing more to offer than the usual bromides about how everyone needs to work together.

See the entry >

Examples:

“According to the old bromide, the grass is greener on the other side of the fence. My grandfather, who had limited formal education but a wealth of common sense, countered that with, ‘Just water and fertilize your own grass. After all, it's your grass and you are in charge of how it grows! Besides, that other stuff may be nothing but AstroTurf.'” — Rodger Dean Duncan, Forbes, 4 Sept. 2024

Did you know?

A bromide is a statement so worn and trite as to be ineffective when it's offered to make someone feel better. Before the sigh-inducing type, though, bromides were most familiar in compounds like potassium bromide, used in the late 19th century as a sedative to treat everything from epilepsy to sleeplessness. (The chemical element bromine had been discovered in 1826.) Such compounds fell from use with the invention of barbiturates in the early 20th century, around the same time that the word bromide started to be applied to anything or anyone dull enough to make one drowsy.

Merriam-Webster's Word of the Day for November 7, 2025 is:

vamoose • \vuh-MOOSS\  • verb

Vamoose is an informal word that means "to depart quickly."

// With the sheriff hot on their tails, the bank robbers knew they had better vamoose.

See the entry >

Examples:

"... I spotted the culprit, a young racoon, attempting to dislodge one of my feeders. Caught in the act, he ran for his life when I opened the window and told him to vamoose." — Margaret Haylock Capon, The Picton County Weekly News (Ontario, Canada), 19 June 2025

Did you know?

In the 1820s and '30s, the American Southwest was rough-and-tumble territory—the true Wild West. English-speaking cowboys, Texas Rangers, and gold prospectors regularly rubbed elbows with Spanish-speaking vaqueros in the local saloons, and a certain amount of linguistic intermixing was inevitable. One Spanish term that caught on with English speakers was vamos, which means "let's go." Cowpokes and dudes alike adopted the word, at first using a range of spellings and pronunciations that varied considerably in their proximity to the original Spanish form. But when the dust settled, the version most American English speakers were using was vamoose.

Merriam-Webster's Word of the Day for November 6, 2025 is:

conciliatory • \kun-SILL-yuh-tor-ee\  • adjective

Something described as conciliatory is intended to reduce hostility or to gain favor or goodwill.

// As the customer's voice rose, the manager adopted a soothing, conciliatory tone and promised that the situation would be remedied.

See the entry >

Examples:

“When I was younger, and my father found me in bed after my mother had said or done something to send me there, he would sit for a moment by my feet and tell me, in an awkward, conciliatory way, that it wasn't my mother's fault. She was sad, and worried, and she had been sad and worried for a long time, so I had to try harder to be a good, thoughtful child.” — Farah Ali, The River, The Town: A Novel, 2025

Did you know?

If you are conciliatory toward someone, you're trying to win that person over to your side, usually by making them less angry. The verb conciliate was borrowed into English in the mid-16th century and descends from the Latin verb conciliare, meaning “to assemble, unite, or win over.” Conciliare, in turn, comes from the noun concilium, meaning “assembly” or “council.” Conciliatory, which appeared in English a bit later in the 16th century, also traces back to conciliare, and is used especially to describe things like tones, gestures, and approaches intended to turn someone's frown upside down. Another word that has conciliare as a root is reconcile, the earliest meaning of which is “to restore to friendship or harmony.”

Merriam-Webster's Word of the Day for November 5, 2025 is:

lout • \LOUT\  • noun

A lout is an awkward brutish person.

// It was difficult for us to focus on the movie due to the noise coming from the group of louts seated in front of us.

See the entry >

Examples:

“Fortunately for Vince, Jake is about to sell their mother's house, and the proceeds should cover his deep debts. As is often the case with ne'er-do-wells, however, Vince doesn't make anything easy, and [actor Jason] Bateman casts him as an arrogant lout ... who's always playing the angles to his own benefit, damn the damage he causes to everyone else.” — Nick Schager, The Daily Beast, 18 Sept. 2025

Did you know?

Lout belongs to a large group of words that we use to indicate a particular sort of offensive and insensitive person, that group also including such terms as boor, oaf, jerk, and churl. English speakers have used lout in this way since the mid-1500s. Well before the 12th century, however, lout functioned as a verb with the meaning “to bow in respect.” No one is quite sure how—or even if—the verb sense developed into a noun meaning “an awkward brutish person.” The noun could have been coined independently, but if its source was the verb, perhaps the awkward posture of one bowing down led over the centuries to the idea that the bowing person was base and awkward as well.

Merriam-Webster's Word of the Day for November 4, 2025 is:

spontaneous • \spahn-TAY-nee-us\  • adjective

Spontaneous describes something that is done or said in a natural and often sudden way and without a lot of thought or planning. It can describe a person who does things that have not been planned but that seem enjoyable and worth doing at a particular time.

// The kitten captured our hearts, and we made the spontaneous decision to adopt.

// He's a fun and spontaneous guy, always ready for the next big adventure.

Examples:

"The Harlem Renaissance was filled with poetry and song—and with performance, as enshrined in [filmmaker William] Greaves's footage which features many spontaneous, thrillingly theatrical recitations of poems by Bontemps, Hughes, Cullen, and McKay." — Richard Brody, The New Yorker, 23 Sept. 2025

Did you know?

When English philosopher Thomas Hobbes penned his 1654 treatise Of Libertie and Necessitie he included the following: "all voluntary actions … are called also spontaneous, and said to be done by a man's own accord." Hobbes was writing in English, but he knew Latin perfectly well too, including the source of spontaneous; the word comes (via Late Latin spontāneus, meaning "voluntary, unconstrained") from the Latin sponte, meaning "of one's free will, voluntarily." In modern use, the word spontaneous is frequently heard in more mundane settings, where it often describes what is done or said without a lot of thought or planning.

Merriam-Webster's Word of the Day for November 3, 2025 is:

fidelity • \fuh-DELL-uh-tee\  • noun

Fidelity is the quality or state of being faithful to a person, such as a partner or spouse, or a thing, such as one's country. Fidelity can also refer to accuracy or exactness in details, or the degree to which an electronic device (such as a television) accurately reproduces its effect (such as sound or picture).

// After almost three decades on the job, no one can doubt their fidelity to the company.

// The movie's director insisted on total fidelity to the book.

See the entry >

Examples:

“The origins of the role [of ring bearer] actually have their roots in ancient Egypt, where a young boy would be enlisted to carry rings to a couple as a symbol of love, fidelity, and fertility.” — Shelby Wax, Vogue, 10 July 2025

Did you know?

Fidelity came to English by way of Middle French in the 15th century, and can ultimately be traced back to the Latin adjective fidēlis, meaning “faithful, loyal, trustworthy.” While fidelity was originally exclusively about loyalty, it has for centuries also been used to refer to accuracy, as in “questions about the fidelity of the translation.” Nowadays fidelity is often used in reference to recording and broadcast devices, conveying the idea that a broadcast or recording is “faithful” to the live sound or picture that it reproduces.

Merriam-Webster's Word of the Day for November 2, 2025 is:

arbitrary • \AHR-buh-trair-ee\  • adjective

Arbitrary describes something that is not planned or chosen for a particular reason, is not based on reason or evidence, or is done without concern for what is fair or right.

// Because the committee wasn't transparent about the selection process, the results of the process appeared to be wholly arbitrary.

// An arbitrary number will be assigned to each participant.

See the entry >

Examples:

“The authority of the crown, contemporaries believed, was instituted by God to rule the kingdom and its people. England's sovereign was required to be both a warrior and a judge, to protect the realm from external attack and internal anarchy. To depose the king, therefore, was to risk everything—worldly security and immortal soul—by challenging the order of God's creation. Such devastatingly radical action could never be justified unless kingship became tyranny: rule by arbitrary will rather than law, threatening the interests of kingdom and people instead of defending them.” — Helen Castor, The Eagle and the Hart: The Tragedy of Richard II and Henry IV, 2024

Did you know?

Donning black robes and a powdered wig to learn about arbitrary might seem to be an arbitrary—that is, random or capricious—choice, but it would in fact jibe with the word's etymology. Arbitrary comes from the Latin noun arbiter, which means “judge” and is the source of the English word arbiter, also meaning “judge.” In English, arbitrary first meant “depending upon choice or discretion” and was specifically used to indicate the sort of decision (as for punishment) left up to the expert determination of a judge rather than defined by law. Today, it can also be used for anything determined by or as if by chance or whim.

Merriam-Webster's Word of the Day for November 1, 2025 is:

ostracize • \AH-struh-syze\  • verb

To ostracize someone is to exclude them from a group by the agreement of the group's members.

// She was ostracized by her community after refusing to sign the petition.

See the entry >

Examples:

"Telling stories with affection and noodging, [comedian Sarah] Silverman has always been encouraged by her family, who embraced rather than ostracized her for revealing family secrets on the way to reaping howls of laughter." — Thelma Adams, The Boston Globe, 19 May 2025

Did you know?

In ancient Greece, citizens whose power or influence threatened the stability of the state could be exiled by a practice involving voters writing that person's name down on a potsherd—a fragment of earthenware or pottery. Those receiving enough votes would then be subject to temporary exile from the state. Ostracize comes from the Greek verb ostrakízein (itself from the noun óstrakon meaning "potsherd"), used in 5th century Athens for the action of banishing someone by way of such a vote. Someone ostracized today is not exiled, but instead is excluded from a group by the agreement of the group's members.
