Merriam-Webster's Word of the Day

Merriam-Webster's Word of the Day for April 29, 2026 is:





speculate • \SPEK-yuh-layt\ • verb

In general contexts, speculate means "to form ideas or theories about something usually when there are many things not known about it." In contexts relating to business or finance, it means "to invest money in ways that could produce a large profit but that also involve a lot of risk."

// Scientists speculate that the newly discovered exoplanet could host liquid water.

// Their research explores the implications of so many people speculating on the stock market in the years leading up to the Great Depression.

Examples:

"Bad Bunny wore an all-cream ensemble consisting of a collared shirt and tie, chinos and a sport-inspired jersey bearing the name "Ocasio"—his surname—and the number 64. The significance of the number was not confirmed, but fans were quick to speculate that it referenced his mother's birth year." — Lara Owen, The Independent (United Kingdom), 9 Feb. 2026





Did you know?

It might be said that what separates our species from others is our tendency "to meditate on or ponder a subject." That's the original 16th century meaning of speculate. It's a use not too distant from today's most common sense, which also involves the mind and thinking: when someone speculates about something, they think and make guesses about it, often forming unsubstantiated ideas or theories. But the origins of speculate lie not in thinking but in looking—the word comes from Latin specere, meaning "to look," or "to look at." We don't have to look far to find other specere descendants, and we'll point them out here with some italics: a cursory inspection reveals spectacle, spectrum, specimen, and perspective. Less conspicuous are despise, prospect, and species.

Merriam-Webster's Word of the Day for April 28, 2026 is:





evanescent • \ev-uh-NESS-unt\ • adjective

Evanescent is a formal and literary word that describes something that only lasts a very short time.

// Our acting coach always reminded us that fame is evanescent, and that we should pursue a life in the theater purely for the love of the art.

Examples:

"Franklin once sternly confiscated a customer's espresso and refunded his money because he took too long sipping it and thus allowed the evanescent flavors to dissipate." — Kirkus Reviews, 8 Jan. 2026





Did you know?

Evanescent didn't appear in the English language out of thin air; it comes from a form of the Latin verb evanescere, which means "to fade away" or "to disappear." (Evanescere is also the ultimate source of vanish.) Given the similarity in spelling and meaning between the two words, you might expect evaporate to trace back to evanescere as well, but its source is another steamy Latin root, evaporare. While today evanescent is used to describe things that last only a short time, the word could formerly also describe the incalculably small. That use is now archaic, meaning it has almost blown away on the breeze.

Merriam-Webster's Word of the Day for April 27, 2026 is:





boondoggle • \BOON-dah-gul\ • noun

A boondoggle is an expensive and wasteful project usually paid for with public money. Boondoggle is also a word for a braided cord worn by Boy Scouts as a neckerchief slide, hatband, or ornament.

// Critics say the dam is a complete boondoggle—over budget, behind schedule, and unnecessary.

Examples:

"A controversial proposal to construct a new bridge from Bridgeport to Long Island is either a bold, visionary step into the future or an unaffordable boondoggle that could cost more than $50 billion." — Christopher Keating, The Hartford (Connecticut) Courant, 8 Mar. 2026





Did you know?

When boondoggle popped up in the early 1900s, lots of people tried to explain where the word came from. One theory traced it to an Ozarkian word for "gadget," while another related it to the Tagalog word that gave us boondocks. Another hypothesis suggested that boondoggle came from the name of leather toys Daniel Boone supposedly made for his dog. But the only theory that is supported by evidence is much simpler. In the 1920s, Robert Link, a scoutmaster for the Boy Scouts of America, apparently coined the word to name the braided leather cords made and worn by scouts. The word came to prominence when such a boondoggle was presented to the Prince of Wales at the 1929 World Jamboree, and it's been with us ever since. Over time, it developed the additional sense describing a wasteful or impractical project.

Merriam-Webster's Word of the Day for April 26, 2026 is:





onerous • \AH-nuh-rus\ • adjective

Onerous means "involving, imposing, or constituting a burden." It typically describes something that is difficult and unpleasant to do or deal with.

// They were assigned the onerous task of post-show cleanup.

// The government imposed onerous taxes on imports.

Examples:

"Morton professed joy at relinquishing politics and announced his intention to retire to his country estate, where he would henceforth be occupied with nothing more onerous than straightening out the pathways in his beautiful gardens." — Gareth Russell, The Six Loves of James I, 2025





Did you know?

The story behind onerous is at once straightforward and, dare we say, poetic. But perhaps that's putting the cart before the horse. Onerous rolled into the English language during the 14th century, via Middle French, from the Latin adjective onerosus, "burdensome." That word, in turn, was hitched to the noun onus, meaning "burden" (source too of our word onus, which usually refers to a burden or responsibility). Onus shares an ancient root with the Sanskrit word anas, meaning "cart." So although onerous stresses a sense of laboriousness and often figurative heaviness (especially because something is distasteful, e.g. "the onerous task of cleaning up the mess"), it has a deep connection with a literal weight borne by a person, horse, or other beast of burden.

Merriam-Webster's Word of the Day for April 25, 2026 is:





juxtapose • \JUK-stuh-pohz\ • verb

To juxtapose things is to place them together in order to create an interesting effect or to show how they are the same or different.

// The local museum’s new exhibit juxtaposes modern art with classical art.

See the entry >





Examples:

“... on ‘Murder Most Foul’ [Bob] Dylan thwarts readymade nostalgia, an easy revisiting of the storybook sixties and his golden ‘spokesman’ moment. Instead, mixing and juxtaposing voices, lingos, and tones, he traces the decline of America over the trajectory of his own lifetime ...” — Robert Polito, After the Flood: Inside Bob Dylan’s Memory Palace, 2026





Did you know?

Although it doesn’t feature the word juxtapose, a classic segment from a 1969 episode of Sesame Street perfectly illustrates the essence of the verb. In it, the character Bob (as played by actor Bob McGrath) sings the catchy song “One of These Things (Is Not Like the Others)” in front of a display that juxtaposes—that is, places near one another for comparison—four items: an apple, an ice cream cone, a hamburger, and a mitten. The song asks its audience to consider their similarities and differences before deciding which is the most different (spoiler alert: it’s the mitten). The word juxtapose is likely a back-formation of the noun juxtaposition, which appropriately enough combines the Latin adjective juxta meaning “near” with the English word position. The use of juxtapose isn’t limited to tangible objects, however—images, ideas, concepts, and more are frequently juxtaposed.
