pantheon

Merriam-Webster's Word of the Day for June 24, 2026 is: pantheon • \PAN-thee-ahn\  • noun Pantheon usually refers to a group of famous or notable people or things. It also refers to the officially recognized gods of a particular people, as well as to the Roman Pantheon, the domed temple begun in 27 B.C. and rebuilt circa 118-128 A.D. // With her induction into the Rock and Roll Hall of Fame, the distinguished bassist and songwriter joined a pantheon of musical legends. // His research is primarily dedicated to the Greek and Roman pantheons. See the entry > [https://www.merriam-webster.com/dictionary/pantheon] Examples: "From cheeky shots of celebrities like Jane Fonda and Arnold Schwarzenegger to extravagant, sensual portfolios of America's Olympic squads, the magazine's pantheon of photographers have helped to define the genre of sports portraiture." — Kahina Sekkaï, Vanity Fair, 14 May 2026 Did you know? Some of the earliest uses of pantheon in the English language refer to the most famous Pantheon [https://www.britannica.com/topic/Pantheon-building-Rome-Italy], the circular domed temple built in Rome more than 19 centuries ago (and still standing). We can easily identify the origins of the temple's name, which the Romans borrowed from the Greek word for a temple honoring all their gods. That Greek word, pantheion, combines pan- ("all") and theos ("god"). In today's English, pantheon often refers to all the gods of a particular people (as in "the Egyptian pantheon"), a sense that arose in the 16th century but was rarely used until the 19th century. More often, though, pantheon bears a meaning developed later to refer to the eminent company of the highly venerated, be they human or not. A pantheon of this type includes no deities; it is a group of famous or notable people or things, as in "a book joining the pantheon of great world literature."

quail

Merriam-Webster's Word of the Day for June 23, 2026 is: quail • \KWAIL\  • verb To quail is to feel afraid and often to show your fear in a way that can be clearly seen. // Although giving a 5-minute speech was a requirement for passing the class, a few students quailed at the thought of public speaking, seeming to shrink behind their desks. See the entry > [https://www.merriam-webster.com/dictionary/quail#dictionary-entry-2] Examples: “Several came to protest but didn’t want their own voices cited. A woman holding a sign reading ‘I’M A 77 YEAR OLD GRANNY FOR FREEDOM’ quailed at the prospect of having her photo in the newspaper.” — Neil Steinberg, The Chicago Sun-Times, 19 Oct. 2025 Did you know? Turning to the noun quail [https://www.merriam-webster.com/dictionary/quail], referring to any of a number of chicken-related game birds, for information about the verb quail is of little help. The two are etymologically unrelated, and there’s nothing specific in the behavior of quails to suggest the verb’s meaning. But never fear—the next time you hear quail, think quiver [https://www.merriam-webster.com/dictionary/quiver#h2] instead. Although quail and quiver are also unrelated, they both start with a distinctive qu and have meanings involving a physical reaction to fear. When you quiver (as in response to, say, hearing things that go bump in the night), you shake or move with a slight trembling motion. Quailing often goes a bit beyond trembling; quail implies shrinking or cowering in fear, as perhaps when the things that go bump in the night suddenly start approaching.

cavalcade

Merriam-Webster's Word of the Day for June 22, 2026 is: cavalcade • \kav-ul-KAYD\  • noun Cavalcade most often refers to a series of related things. An older meaning, still in use, is “a procession of riders or carriages”; vehicles or ships in a procession can be referred to as a cavalcade too. // Since the high-powered console’s debut late last year, video game companies have steadily unveiled a cavalcade of new games that showcase its groundbreaking graphics. See the entry > [https://www.merriam-webster.com/dictionary/cavalcade] Examples: “The event opened with a cavalcade of musicians, dancers and local children, followed by a horse-drawn carriage carrying the Watercress King and Queen ... who threw bags of freshly harvested watercress into the crowd as they paraded up and down Broad Street.” — Paul Coates, The Haslemere (England) Herald, 18 May 2026 Did you know? Cavalcade is a word with deep equestrian [https://www.merriam-webster.com/dictionary/equestrian] roots: it comes (via French and probably Italian [https://www.merriam-webster.com/dictionary/cavalcade#word-history]) ultimately from the Latin word caballus, meaning “work horse” or “gelding [https://www.merriam-webster.com/dictionary/gelding].” (Spanish speakers may recognize the influence of caballus in the word caballo, meaning “horse.”) In the 17th century, cavalcade was used specifically to refer to a procession of horseback riders or carriages, especially as part of a special occasion, whether joyous or funereal. Over time, that meaning was extended to processions of other modes of travel, including ships, vehicles, or even paraders on foot or float (as invoked by the late singer-songwriter Elliott Smith in his song “Rose Parade” with the lyric “a wink and a wave from the cavalcade”). As a cavalcade of words before and since have done, cavalcade also took on a figurative sense to refer to a series of related things, whether or not they happen to be marching (or trotting) down the road.

assiduous

Merriam-Webster's Word of the Day for June 21, 2026 is: assiduous • \uh-SIJ-uh-wus\  • adjective Assiduous is a formal word that means “showing great care, attention, and effort.” // Thanks to the assiduous efforts of the local land trust over many years, a substantial amount of whip-poor-will [https://www.merriam-webster.com/dictionary/whip-poor-will] habitat is now protected from development. See the entry > [https://www.merriam-webster.com/dictionary/assiduous] Examples: “My mom was also assiduous about what we would today call food safety, avoiding anything that could possibly cause illness, especially raw meat: ‘Well done’ was the norm for everything, and anything that could possibly go bad was kept in the fridge.” — James Martin, Work in Progress: Confessions of a Busboy, Dishwasher, Caddy, Usher, Factory Worker, Bank Teller, Corporate Tool, and Priest, 2026 Did you know? While assiduous means “showing great care, attention, and effort,” and in some situations may be an appropriate substitute for careful [https://www.merriam-webster.com/dictionary/careful], it’s got a bit more oomph than careful in that it suggests a dogged or tireless persistence. If you are assiduous in your efforts (or work, research, analysis, training, preparations, etc.) for example, it’s implied that you’re in it for the long haul, or that you have the ability to “sit with” a task or challenge for a considerable amount of time. This idea is fitting given that assiduous comes from the Latin verb assidēre, meaning “to sit beside.”

longueur

Merriam-Webster's Word of the Day for June 20, 2026 is: longueur • \lawn-GUR\  • noun Longueur refers to a boring part of something (such as a book or play). It is usually used in the plural form. // Though not without its longueurs, the opera came to life in the last act. See the entry > [https://www.merriam-webster.com/dictionary/longueur] Examples: “Game 3 of the World Series was a stone-cold thriller, with peaks of high drama and longueurs of exquisitely tense tedium ...” — Steve Rushin, The Atlantic, 2 Nov. 2025 Did you know? You’ve probably come across long, tedious sections of books, plays, or musical works before, but perhaps you didn’t know there was a word for them. The French borrowing longueur has been doing the job for us since the late 18th century. As in English, French longueurs are tedious passages, with longueur itself literally meaning “length.” An early example of longueur used in an English text is from 18th-century writer Horace Walpole [https://www.britannica.com/biography/Horace-Walpole], who wrote in a letter, “Boswell’s book is gossiping; ... but there are woeful longueurs, both about his hero and himself.”
