Examples:

“‘Hombre al Agua’ starts out playful and grows more overtly comic, particularly once politics is thrown into the mix. At one point, a character compares the film’s milieu, the world of the rich, to old sci-fi movies where astronauts land on a planet that looks a lot like earth but turns out to be completely different.” — Steve Pond, The Wrap, 6 Sept. 2026





Did you know?

It’s not difficult to locate another word within the milieu of milieu, whose final four letters spell lieu. Lieu is an archaic word meaning “place,” today used almost exclusively in “in lieu of” (= in the place of), as in “in lieu of cash a credit card is acceptable.” English users borrowed this lieu from Anglo-French—the French language used in medieval England—in the 13th century. It wasn’t until many centuries later, in the mid-1880s, that English adopted milieu from the French spoken in France. (In Old French, milieu meant “midst,” from mi, meaning “middle,” + lieu.) Both milieu and lieu have an ancestor in the Latin word for place, locus, as does many an English word, including locate.

Examples:

"Some of the spacious galleries feature a single artist ... one is devoted to murals, another to architecture, but many are organized by themes rather than genre, period, place or, and this is important, prestige. Thematic grouping of disparate work has become a popular, though not uncontroversial, trend." — Mary McNamara, The Los Angeles Times, 3 Sept. 2026





Did you know?

If you enjoy sorting different objects into separate categories, you're well prepared to understand the origins of disparate. The word, which first appeared in English in the 16th century, comes from the Latin verb disparāre, meaning "to divide, separate off, make different." Disparāre, in turn, comes from parāre, a verb meaning "to supply, provide, make ready or prepare." Other descendants of parāre in English include both separate and prepare, as well as repair, apparatus, and even the pugnacious vituperate ("to criticize harshly and usually publicly").

Examples:

“Brian [Jones] had enjoyed being in control of the band. He’d arranged their gigs, negotiated their deals, served as their spokesman; he was their emissary with the press, making regular visits to Record Mirror and Melody Maker.” — Bob Spitz, The Rolling Stones: The Biography, 2026





Did you know?

If you’re a big cheese or big kahuna, you may often find yourself too crunched for time to meet face-to-face with your fellow bigwigs, let alone the hoi polloi. In such cases, a good solution is to send out an emissary, someone to act as your representative and shake the necessary hands, grease the necessary palms, etc. The operative phrase here is “send out”; emissary comes from Latin emittere, meaning “to send out.” When emissary was first adopted in the early 17th century, it typically emitted bad vibes (emit also hails from emittere), carrying the implication that the business of an emissary was dishonest or corrupt. But today, that connotation has faded completely, and emissaries are those simply sent to act on someone's behalf.

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





puissant • \PWISS-unt\ • adjective

Puissant is a synonym of powerful used to describe something with puissance—that is, strength or power.

// The creatures in her fantasy novel are wielders of puissant magic, able to strike down enemies by harnessing the power of weather phenomena like lightning and tornadoes.

Examples:

“The show is light on tech, but the accompanying images … pour through as addendums to Felder's puissant passion of Liszt's Liebesträume or Beethoven's Für Elise and land with great effect.” — David John Chávez, The Mercury News (San Jose, California), 1 Feb. 2026





Did you know?

Puissant has some powerful ties to some more commonplace English words. Although puissant has a considerably fancier feel than power and potent, all three words share the same Latin ancestor: posse, a verb meaning “to be able.” Potent came from potent-, potens, a form of posse. Power came to us by way of Anglo-French poer, which itself comes from an alteration of posse. From poer also came the Anglo-French adjective pussant, meaning “able” or “powerful,” and English speakers borrowed that to form puissant in the 15th century.

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





asunder • \uh-SUN-der\ • adverb or adjective

Asunder is most often used as an adverb—often with a verb such as tear or rip—to mean "apart" or "into pieces." It is more rarely used as an adjective meaning "apart from each other," as in "standing with legs wide asunder."

// The park was torn asunder by yesterday's microburst, and many of its trails have been blocked by fallen trees.

Examples:

"We cannot see erosion but we know it happens. [Artist Harrison] Bowe's work is filled with hints of vastness, but he's also pointing to how water might carve a mountain asunder." — Andrew Harper, Hobart Mercury (Australia), 6 Dec. 2025





Did you know?

To get to the root of today’s word, it helps to take it apart and focus on the sunder. You see, asunder comes from the verb sunder, which means "to break apart" or "to become parted, disunited, or severed." Both words come from the Old English word sundor, meaning "apart." The adverbial "into parts" sense of asunder is often used in the phrase "tear asunder," which can be used both literally (as in "fabric torn asunder") and, more often, figuratively (as in "a community torn asunder by the dispute"). The adjectival "apart from each other" sense can be found in the phrase "poles asunder," used to describe two things that are as vastly far apart as the poles of the Earth.
