Examples:

“The first half of Alice Winn’s bestselling In Memoriam is set at Preshute, an English boys’ boarding school in the early twentieth century. It is here, in the idyllic countryside, where the boys discuss poetry and get up to all sorts of high-jinks and japes, and where two students, Gaunt and Ellwood, fall in love. Then the boys are ejected into the horror and abyss of WWI trenches. When they are reunited, mentally and physically scarred, Preshute is but a dream and their adolescent love, a halcyon place that can only be returned to in memory.” — Madeleine Dunnigan, LitHub.com, 16 Jan. 2026

Halcyon has drifted along contentedly in English for centuries, but it hatched from a tumultuous story. According to Greek mythology, Alkyone, the daughter of the god of the winds, became so distraught over her husband Ceyx’s death at sea that she threw herself into the ocean to join him. The gods were moved by the couple’s love, and took pity on them by turning them into halcyon birds, a bird identified with the kingfisher. (Kingfishers are known for plunging into water after prey.) According to the legend, the birds built their nests on the sea, which so charmed Alkyone’s father that he created a period of unusual calm that lasted until the birds’ eggs hatched. Our word halcyon reflects the story in multiple ways. When halcyon was first used in English in the 14th century it was as a noun referring to the mythical bird, and later to actual kingfishers as well. Adjective use developed in the 16th century and now most often evokes those calm waters: the word typically describes an idyllic time in the past.

Examples:

“These days, she can be found gallivanting around the Upper West Side, catching the latest Broadway shows and occasionally hopping onstage to belt show tunes with the waitstaff at her beloved Times Square restaurant, where she remains hands-on with the business.” — McKenzie Beard, The New York Post, 18 Feb. 2026





Did you know?

Back in the 14th century, gallant, a noun borrowed from the French word galant, referred to a fashionable young man. By the middle of the next century, it was being used more specifically to refer to such a man who was attentive to, and had a fondness for, the company of women. In the late 17th century, this “ladies’ man” sense gave rise to the verb gallant to describe the process a suitor used to win a lady’s heart, and “gallanting” became synonymous with “courting.” It’s this verb gallant that is the likely source of gallivant, which originally meant “to act as a gallant” or “to go about usually ostentatiously or indiscreetly with members of the opposite sex.” Today, however, gallivant is more likely to describe pleasurable wandering than romancing.

wistful • \WIST-ful\ • adjective

To be wistful is to have sad thoughts and feelings about something that you want to have or do, and especially about something that made you happy in the past. Wistful can also describe something, such as a smile or sigh, that shows or communicates such feelings.

Examples:

"Postcards have always been an object of fascination for me. I remember flipping through photo albums as a young girl and coming across those sent to my parents, from people I had never met. When I asked who these people were, I would hear wistful stories." — Minoli Wijetunga, The Guardian (London), 10 Jan. 2026





Did you know?

We see you there, dear reader, gazing silently up at the moon, heart aching to know the history of wistful, as if it could be divined on the lunar surface. And we'd like to ease your melancholy by telling you that the knowledge you seek—nay, pine for—is closer at hand. The word wistful comes from wistly, a now-obsolete word meaning "intently," and the similar-sounding wishful. Wistly, in turn, likely comes from whist, an old term meaning "silent." What's more certain is that our modern wistful is a great word to describe someone full of pensive yearning, or something inspiring such yearning.

dudgeon • \DUJ-un\ • noun

Examples:

“She was in high dudgeon because her expensive lunch was punctuated by noise from a child ‘a real menace’ whose parents, she said, appeared oblivious to the noise while staff … played with and entertained the tot. If the parents could afford the bill for a place like that, they could afford a babysitter, she snipped.” — Rachel Moore, The Eastern Daily Press (Norwich, England), 6 Feb. 2026





Did you know?

Dudgeon is today most often used in the phrase “in high dudgeon” to describe someone in a fit of pique, or more colloquially, in a snit: they are angry and offended because of something they perceive as unfair or wrong. The word has been a part of the English language since at least the late 1500s, but its origins are a mystery. Conjectures connecting dudgeon to a Welsh word, dygen, meaning “malice,” have no basis. Also, there does not appear to be any connection to an even older dudgeon—a term once used for a dagger or a kind of wood out of which dagger handles were made.

Examples:

“[Helen] McCrory’s flamboyant and perfectly drawn portrayal of Polly was the show’s real treasure, a steel-willed matriarch unusually attuned to the mysticism of the Shelby family’s Romani roots who also served as a ruthlessly pragmatic consigliere. ... McCrory’s Polly was so electric that the show remained totally riveting any time she was onscreen.” — Jack Hamilton, Slate, 20 Mar. 2026





Did you know?

Associate the word flamboyant with bananas flambé and the word’s fiery etymology will be seared in your mind. Flamboyant, which was borrowed into English from French in the 19th century, can be traced back to the Old French word flambe, meaning “flame.” In its earliest uses flamboyant referred to an ornate style of Gothic architecture popular in France and Spain, which featured waving curves suggestive of flames. Eventually, the word developed a more general second sense for anything eye-catching or showy. And of course, flambe is also the origin of the English adjective flambé, which describes food flamboyantly dressed or served with flaming liquor.
