Merriam-Webster's Word of the Day

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

Examples:

“... conducting requires more than merely gesturing with a baton—some pieces of music are tantamount to 80 minutes of hard cardio ...” — Mark Shanahan, The Boston Globe, 15 Mar. 2026





Did you know?

Although tantamount (from the Anglo-French phrase tant amunter, meaning “to amount to as much”) was used three different ways in the early 17th century—as a noun, verb, and adjective—the adjective form has since proven paramount to English users: it’s still in use while the noun and verb are obsolete. This is not to say that the adjective hasn’t experienced change over the years. While it was once acceptable to use tantamount in a variety of different sentence structures, nowadays it is almost always followed by the word to. And to use it before a noun, as in “the two old friends exchanged tantamount greetings,” would now be considered, er, tantamount to riding a penny-farthing or boneshaker onto the expressway.

Examples:

“Ormin, a medieval monk, sought to bring order to English orthography by addinng morre letterrs to worrds. August Thibaudin, a London professor, tried 9dding n3mbers. Our ideas for simplifying spelling have ranged from the rashonal to the redikulus to the döunnryt ubsërrd, and with each whimsical solution we seem to get further away from cognitive stability.” — Gabe Henry, Enough is Enuf: Our Failed Attempts to Make English Eezier to Spell, 2025





Did you know?

The concept of orthography (a term that comes from the Greek words orthos, meaning “right or true,” and graphein, meaning “to write”) was not something that really concerned English speakers until the introduction of the printing press in England during the 15th century. From that point on, English spelling became progressively more uniform. Our orthography has been relatively stable since the 1755 publication of Samuel Johnson’s A Dictionary of the English Language, with the notable exception of certain spelling reforms, such as the change of musick to music. Incidentally, many of these reforms were championed by Merriam-Webster’s own Noah Webster.

Merriam-Webster's Word of the Day for April 20, 2026 is:





indoctrinate • \in-DAHK-truh-nayt\ • verb

To indoctrinate someone is to teach them to fully accept the ideas, opinions, and beliefs of a particular group while categorically rejecting other ideas, opinions, and beliefs.

// The video series attempts to indoctrinate younger audiences with ahistorical and unscientific ideas.

Examples:

"They worry about being 'cut off' from poetry, particularly by the jobs that they need to sustain their daily lives and that they fear may quietly indoctrinate them into a contrary value system." — Katy Waldman, The New Yorker, 2 Feb. 2026





Did you know?

Indoctrinate means "brainwash" in most contexts today, but its meaning wasn't always so negative. When the verb first appeared in English in the 17th century, it simply meant "to teach"—a meaning linked closely to its source, the Latin verb docēre, which also means "to teach." (Other offspring of docēre include docile, doctor, document, and, of course, doctrine). By the 19th century, indoctrinate was being used in the sense of teaching someone to fully accept only the ideas, opinions, and beliefs of a particular group.

Merriam-Webster's Word of the Day for April 19, 2026 is:





nugatory • \NOO-guh-tor-ee\ • adjective

Something described as nugatory is of little or no consequence. In law, nugatory describes something (such as a statute or agreement) without operative legal effect.

// Most of the criticism of the film in the weeks since its release has been nugatory nonsense.

// This new contract renders the previous agreement nugatory.

Examples:

“Public outrage, fanned by the press, did not engage with the work but focused instead on taxpayers’ money having been squandered on a worthless ‘pile of bricks.’ In fact, the purchase price of [pounds sterling] 2,297 was nugatory, but the issue was never really about price but about rejecting the new and the challenging in art.” — Art Monthly, 1 Dec. 2025





Did you know?

Just because nugatory isn’t the most common word in the English language doesn’t mean it’s trifling. Rather, nugatory is literally trifling because the two words are synonymous, as in “comments too nugatory to merit attention.” Nugatory first appeared in English in the 17th century; it comes from the Latin adjective nugatorius, which can mean not only “trifling” or “frivolous” but also “futile.” This sense carried over into English as well, and so in some contexts nugatory means “ineffective” or “having no force,” as when Pulitzer Prize-winning novelist Marilynne Robinson invoked “the nugatory value of the contemporary penny.” Nugatory may mean little to some, but we think it’s worth a pretty penny.

Merriam-Webster's Word of the Day for April 18, 2026 is:





hiatus • \hye-AY-tus\ • noun

In general contexts, hiatus usually refers to a period of time when something, such as an activity or program, is suspended. In biology, hiatus describes a gap or passage in an anatomical part or organ, and in linguistics, it refers to the occurrence of two vowel sounds without pause or intervening consonantal sound.

// The actor, who’s been on hiatus for several years, will be starring in a new film.

Examples:

“Following its return in 2025 after a nearly three-year hiatus, the 52nd American Music Awards are heading back to Las Vegas to be broadcast live from a new venue, the MGM Grand Garden Arena.” — Steven J. Horowitz, Variety, 10 Mar. 2026





Did you know?

This brief hiatus in your day is brought to you by, well, hiatus. While the word now most often refers to a temporary pause, hiatus originally referred to a physical opening in something, such as the mouth of a cave, or, as the 18th century British novelist Laurence Sterne would have it, a sartorial gap: in the wildly experimental novel Tristram Shandy, Sterne wrote of “the hiatus in Phutatorius’s breeches.” Hiatus comes from the Latin verb hiare, meaning “to yawn,” which makes it a distant relation of both yawn and chasm. And that’s all we have for now—you may resume your regular activities.
