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

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.

puissant • \PWISS-unt\ • adjective

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.

Merriam-Webster's Word of the Day for October 22, 2026 is:





vocation • \voh-KAY-shun\ • noun

Vocation can refer simply to an occupation, or it can refer to a strong calling to pursue a particular kind of work or course of action.

// Since he was a teenager, he knew that he would find his vocation in marine biology.

Examples:

“Through her education and her father’s encouragement, she had nurtured a vocation for literature and was determined to make a career for herself in the bundan, Japan’s literary elite …” — Bryan Karetnyk, introduction to Troubled Waters by Higuchi Ichiyō, 2026





Did you know?

When vocation was first used in English in the 15th century it referred specifically to a summons from God to perform a particular task or function in life, especially a religious one. This meaning is no surprise given the word’s source: it comes from the Latin vocation-, vocacio, meaning “summons,” which in turn comes from vocāre, meaning “to call.” Vocation also has a non-religious function in the English language as a word for the strong desire to do a certain kind of work, or as a word for the work itself, making vocation a synonym of the words calling and occupation.

Examples:

“The set suggests Miss Havisham’s room in her estate, which was famously frozen in time from the moment her fiancé jilted her in the Dickens novel, but that’s simply the frame for a behind-the-scenes view into all of the elements ... that go into an actor’s effort to bring a character to life on stage.” — Terry Byrne, The Boston Globe, 20 May 2026

What’s in a name? Often, something not very nice, through no fault and much to the chagrin of those bearing that name. Just ask Ralph or Karen. The same is (possibly) true of Gillot, an old pet form of Gillian that is thought to have led to the noun jillet, which originally referred to an unfaithful wife, and later became jilt, used in the late 17th century for a person (especially a woman) who capriciously casts a lover aside. The verb jilt followed for the actions of such a person. These days, though jilt usually implies the sudden ending of a romantic relationship, it can also be used beyond that context with the broader meaning “to sever close relations with.”
