Merriam-Webster's Word of the Day

Examples:

"My tendency to throw remote historical observations into a conversation exasperates my wife and often results in chuckles and eye rolls from friends." — Angus Scott, The Niagara Falls (Ontario) Review, 28 Mar. 2026





Did you know?

Exasperate is frequently confused with exacerbate, and with good reason. Not only do these words resemble one another in spelling and pronunciation, they also at one time held exceedingly similar meanings. Exasperate is today most commonly used as a synonym of annoy, but for several hundred years it also had the meanings "to make more grievous" and "to make harsh or harsher." Exacerbate is now the more common choice when one seeks to indicate that something is becoming increasingly bitter, violent, or unpleasant. It comes in part from the Latin word acer, meaning "sharp," whereas exasperate is from asper, the Latin word for "rough." The latter is also the source of the English asperity, which can refer to the roughness of a surface or the roughness of someone's temper.

Merriam-Webster's Word of the Day for May 1, 2026 is:





Beltane • \BEL-tayn\ • noun

Beltane refers to the Celtic May Day festival.

// Beltane falls each year approximately halfway between the spring equinox and the summer solstice.

See the entry >





Examples:

“On May 1, we celebrate what began as the ancient Celtic holiday of Beltane. ... It started at sundown April 30, when, according to Celtic lore, the evil spirits that had wreaked havoc on humans since Halloween had a last fling before the dawning of May 1 cast them into their annual six-month exile. The night of April 30 is still celebrated, especially abroad, with bonfires and revelry.” — Deane Morrison, The Owatonna (Minnesota) People’s Press, 26 Mar. 2026





Did you know?

To the ancient Celts, May Day marked the start of summer, and a critical time when the boundaries between the human and supernatural worlds were removed, requiring that people take special measures to protect themselves against enchantments. The Beltane fire festival originated in a summer ritual in which cattle were herded between two huge bonfires to protect them from evil and disease. The word Beltane has been used in English since the 15th century, but the earliest known instance of the word in print—as well as the description of that summer ritual—appears in an Irish glossary commonly attributed to Cormac, a king and bishop who lived in the south of Ireland near the end of the first millennium.

Merriam-Webster's Word of the Day for April 30, 2026 is:





interlocutor • \in-ter-LAH-kyuh-ter\ • noun

Interlocutor is a formal word that means “one who takes part in dialogue or conversation.”

// It is crucial in our age of email scams to verify the validity of one’s online interlocutors before sharing sensitive information.

Examples:

“I remember sitting alone on the train platform, and then on the train, with no interlocutor but the poem. I read it once. I read it again. And in the blank spaces between the verses, I started to translate.” — Hannah Kauders, LitHub.com, 3 Dec. 2025





Did you know?

It may not necessarily be grandiloquence to use the word interlocutor in casual speech, but if your interlocutors—that is, the people with whom you are speaking—are using it, your conversation is likely a formal one. Interlocutor is one of many English words that comes from the Latin verb loqui, “to speak,” including loquacious (“talkative”), eloquent (“capable of fluent or vivid speech”), and grandiloquence (“extravagant or pompous speech”). In interlocutor, loqui was joined to inter- forming a Latin word meaning “to speak between” or “to issue an interlocutory decree.” An interlocutory decree is a judicial decision that isn’t final, or that deals with a point other than the principal subject matter of the dispute.

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.

See the entry >





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.
